12
202660 REV AB
High Power Outdoor SSPA Operations Manual
1.6.1 High Voltage Hazards
High Voltage, for the purpose of this section, is any voltage in excess of 30V. Voltages
above this value can be hazardous and even lethal under certain circumstances. Care
should be taken when working with devices that operate at high voltage.
•
•
•
•
•
All probes and tools that contact the equipment
should be properly insulated to prevent the operator
from coming in contact with the voltage.
The work area should be secure and free from nonessential items.
Operators should never work alone on high voltage
devices. There should always be another person present in the same work area to assist in the event of
an emergency.
Operators should be familiar with procedures to employ in the event of an
emergency, i.e., remove all power, CPR, etc.
An AC powered unit will have 230 VAC entering through the AC power
connector. Caution is required when working near this connector, the AC
circuit breaker, or the internal power supply.
1.6.2 High Current Hazards
Many high power devices are capable of producing large
surges of current. This is true at all voltages, but needs to
be emphasized for low voltage devices. Low voltage
devices provide security from high voltage hazards, but also
require higher current to provide the same power. High
current can cause severe injury from burns and explosion.
The following precautions should be taken on devices
capable of discharging high current:
•
•
•
•
•
Remove all conductive personal items (rings, watches, medals, etc.)
The work area should be secure and free of non-essential items.
Wear safety glasses and protective clothing.
Operators should never work alone on high risk devices. There should
always be another person present in the same area to assist in the event
of an emergency.
Operators should be familiar with procedures to employ in the event of an
emergency, i.e., remove all power, CPR, etc.
Large DC currents are generated to operate the RF Module inside of the enclosure.
Extreme caution is required when the enclosure is open and the amplifier is operating.
Do not touch any of the connections on the RF modules when the amplifier is operating. Currents in excess of 60 Amperes may exist on any one connector.

1.6.3 RF Transmission Hazards
RF transmissions at high power levels may cause eyesight damage and skin burns.
Prolonged exposure to high levels of RF energy has been linked to a variety of health
issues. Please use the following precautions with high levels of RF power.
•
•
•
•
Always terminate the RF input and output
connector prior to applying prime AC input power.
Never look directly into the RF output waveguide
Maintain a suitable distance from the source of the
transmission such that the power density is below
recommended guidelines in ANSI/IEEE C95.1. The
power density specified in ANSI/IEEE C95.1-1992 is
10 mW/cm2. These requirements adhere to OSHA
Standard 1910.97.
When a safe distance is not practical, RF shielding should be used to
achieve the recommended power density levels.
1.6.4 Electrical Discharge Hazards
An electric spark can not only create ESD reliability problems, it can also cause serious
safety hazards. The following precautions should be followed when there is a risk of
electrical discharge:
•
•
•
•
•
•
Follow all ESD guidelines
Remove all flammable material and solvents from the
area.
All probes and tools that contact the equipment
should be properly insulated to prevent electrical discharge.
The work area should be secure and free from nonessential items.
Operators should never work alone on hazardous equipment. There
should always be another person present in the same work area to assist
in the event of an emergency.
Operators should be familiar with procedures to employ in the event of an
emergency, i.e., remove all power, CPR, etc.
1.6.5 High Leakage Current
The equipment may have more than 3.5
mA leakage current. Make sure a connection to earth ground is present before applying prime power, and after removing
prime power.

1.6.6 High Potential for Waveguide Arcing
As with all systems which utilize high power signals within
waveguide, the potential exists for an electric arc to form.
To minimize this risk, Teledyne Paradise Datacom requires all waveguide be pressurized and dehydrated.
1.7 Waveguide Pressurization and Dehydration
When working with high power amplifier systems that operate into waveguide, the inadvertent creation of arcs is always a concern. An arc in waveguide is the air discharge
breakdown due to the ionization of the air molecules by electrons. This breakdown in
waveguide occurs when the rate of electron production becomes greater than the loss
of electrons to diffusion to the surrounding walls.
It is extremely difficult to precisely predict the power levels at which the breakdown occurs. It is dependent on a variety of factors but the primary factors are:
• Waveguide temperature and atmospheric pressure
• Components in the Waveguide Transmission System such as: Flanges,
Bends, Tees, Combiners, Filters, Isolators, etc.
• Load VSWR presented to the amplifier.
When operating such a high power amplifier system it is imperative that the waveguide
transmission system be dehydrated and pressurized. Operation with an automatic air
dehydrator will provide dry pressurized air to ensure that condensation cannot form in
the waveguide. Also the higher the pressure that can be maintained in the waveguide;
the higher the power handling is in the waveguide system. Most commonly available
air dehydrators are capable of providing pressures of 0.5 to 7.0 psig (25-362 mmHg).
At low power levels (uniform field distribution), low pressure can give good results. For
non-uniform conditions, highly localized breakdown can occur. In this case the waveguide system will require much higher pressure. This occurs with bends, waveguide
flange joints. If line currents flow across a small gap introduced by poor tolerances,
flange mismatch, poorly soldered bends, field strengths in excess of that in the main
line can occur in the gap. Pressurization with air or high dielectric gases can increase
the power handling by factors of 10 to 100.
In High Power Amplifier systems an arc will travel from where it is ignited back to the
amplifier. Typical arc travel speed is on the order of 20 ft/sec. Increasing the waveguide pressure can reduce the speed of arc travel. It is difficult to get an accurate calculation of the amount of pressurization needed, but it is a good practice to get as
much pressure as your system can handle. All high power systems that meet the criteria of Table 1-1 are pressure tested at the factory to 1.5 psig. As a guide we recommend using the power levels in Table 1-1 as the threshold levels where special attention be given to dehydration and the overall simplification of waveguide system design.

It is a common misconception to look up the maximum theoretical power handling of a
particular type of waveguide and assume that this is the maximum power handling.
This may be the case for a straight waveguide tube with ideal terminations but these
values must be significantly de-rated in practical systems. Phase combined amplifier
systems can be particularly sensitive to the potential for waveguide arcing. This is due
to the numerous bends, magic tees, multiple waveguide flange joints, and other waveguide components. Table 1-2 shows the power handling capability of some popular
waveguide components normalized to the waveguide power rating. From this table, we
can see how a practical waveguide system’s power handling will de-rate significantly.

Most waveguide systems have many of these components integrated before reaching
the antenna feed. It is not uncommon for a Satcom waveguide network to de-rate to
5% of the straight waveguide power rating.
The load VSWR also has an impact on the breakdown threshold in waveguide networks. Standing waves degrade the power handling of any transmission line network.
The graph of Figure 1-2 shows the rapid degradation of waveguide breakdown vs.
load VSWR. The chart shows that for a 2.0:1 load VSWR, the breakdown potential will
be half of what it would be with a perfectly matched load. This can degrade even more
when high Q elements such as band pass filters are included in the waveguide network.

There are many factors to consider with high power amplifier systems in terms of the
output waveguide network. Especially when using HPA systems with output power
levels of Table 1-1, it is imperative to ensure that the output waveguide network is
pristinely clean and dry. An appropriate dehydrator should be used with capability of
achieving adequate pressure for the system’s output power. Take extra precaution to
make sure that any waveguide flange joints that are not already in place at the factory
are properly cleaned, gasket fitted, and aligned. A properly designed and maintained
waveguide network will ensure that no arcing can be supported and will provide many
years of amplifier service life.

Warning! Always terminate the RF input and output connectors prior to applying prime AC input power!
Leakage current may exceed 3.5 mA. A connection to earth ground must be made prior to connecting AC mains. Likewise, when removing AC mains, keep earth ground
connected.
For the connection to earth ground, use a 12 AWG cable, UL rated for outdoor use.
Connect to the chassis ground stud using the supplied hardware. Tighten all hardware
securely with a wrench.

2.1.3.7.1 Power Cable Construction
Construct a power cable using the supplied MS3106F20-19S mating connector for J7.
Use a three-conductor, 25A, 12 AWG cable, UL rated for outdoor use. When constructing the cable, discard the connector grommet, but keep the plastic ferrule. Connect the
black conductor to terminal A (L1) of the connector, the white conductor to terminal C
(L2/N) of the connector, and the green (protective earth ground) connector to terminal
B (GND) of the connector. Tighten the metal end-bell and fill with potting compound.
Warning! The protective earth pin B must be connected to AC mains
earth for both safety and EMC regulation compliance.
Note: For safety purposes, an isolation switch may be included in the
power cable to serve as a disconnect device in the event of an emergency or for unit servicing. The amplifier itself has no on/off switch. When AC
power is applied to the unit, the unit’s power supplies and microcontroller
are enabled. The internal amplifier module is disabled until the Mute Line
Input (J4, Pin B) is pulled to Ground (J4, Pin V). See Section 2.3.4.
2.1.3.8 +15 VDC Output Port (J8) [MS3112E10-6S]
The 6-pin MS-type female connector at this port is capable of supplying 3 Amps of
current at 15 Volts and can be used to power associated equipment such as Block Up
Converters, Low Noise Amplifiers and Low Noise Block Converters. Table 2-5 shows

PS1(V) — Main power supply 1 output voltage with resolution of 0.1V.
Normal output voltage for GaAs amplifiers is in the range of 11 to 13 V;
The voltage range for GaN amplifiers depends on the frequency band of
the unit. Typical GaN SSPA power supply ranges are:
○ L– and S-Band SSPAs: 40 to 50 VDC;
○ C-Band SSPAs: 24 to 28 VDC;
○ X-Band SSPAs: 20 to 26 VDC;
○ Ku-Band SSPAs: 20 to 28 VDC;
○ Ka-Band SSPAs: 20 to 24 VDC.
PS2(V) — Main power supply 2 output voltage. See above.
Boost1(V) — Booster power supply 1 output voltage with resolution of
0.1V. Normal range 24 to 30 V (typical 28V);
Boost2(V) — Booster power supply 2 output voltage.
DC (A) — Total DC current draw by RF modules from main power supply. Value varies depending on the power level of the HPA. If the HPA is
muted, current normally drops to within the 0 to 5 A range.

Regulator — RF module regulator low voltage fault. Values: “FAULT!” or
“Normal”;
DC Current — Low DC current fault. Values: “FAULT!” or “Normal”;
Temperature — High temperature fault. Values: “FAULT!” or “Normal”.
Temp.(C) — Internal RF module plate temperature in Celsius. In multimodule units, only the hottest module baseplate temperature is displayed.
2.2.1.8 Sys Info Page 8
This page shows individual RF module states in multi-module HPAs.
•
•
Mod# & PreAmp — Mod1 to Mod4 represent the overall state of the relevant RF Power modules. If the amplifier is equipped with a separate preamplifier module, the “PreAmp” value will represent the overall state of
the pre-amplifier. Under normal operation, the value will read “Normal”.
If a unique module does not exist in the HPA configuration, the value
shows “N/A” (not available). Each value represents the summary fault
state of an individual RF module, which includes the Voltage, Current and
Temperature state as well as the quality of data connection with module.
For a module or pre-amp exhibiting a fault condition, the value will read
“FAULT!”.
If the HPA controller card cannot reliably communicate with an SSPA
module, that module will be declared faulted. This type of fault will not affect the overall summary fault state, because the controller card has the
ability to track RF module faults independently. When an existing module
or pre-amp is present in the current HPA configuration, but fails to respond to control board status queries, “ComErr” (Communication Error)
will be displayed.
PSModFlts — For amplifiers utilizing an external N+1 power supply, this
value indicates the number of detected N+1 PS module faults. For units
with an internal power supply, this value reads “000” and should be ignored. Check PS1 and PS2 Voltage readings to assess the state of an
internal power supply.

•
•
•
•
Chssy Temp — Chassis temperature reading measured by the control
board. Since the control board is typically located at rear of the chassis,
this reading correlates with the exhaust air temperature;
RecordHigh — The highest temperature detected over unit lifetime. This
value is updated each time a temperature higher than the current record
is detected. Value could be used for SSPAs problem troubleshooting.
Record data is factory reset only.
BUC PS1(V) — This value represents the power supply voltage used for
biasing an optional BUC unit. Voltage could be used for detecting problems related to BUC operation. The SSPA does not have a specific alarm
threshold for this voltage. Normal reading for this parameter should be in
range of 15V– 16V.
BUC PS2(V) — This value represents secondary BUC power supply voltages. For a unit equipped with a single power supply this value shows “N/

0.0.0.0 or 255.255.255.255 to disable this feature.
Starting with version 6.00, the Lock IP address function has been updated to allow “Binding” and “Masking” functions. Binding" means that the
first datagram retrieved for this socket will bind to the source IP address
and port number. Once binding has been completed, the SSPA will answer to the bound IP source until the unit is restarted or reset. Without
binding, the socket accepts datagrams from all source IP addresses.
Address 0.0.0.0 allows all peers, but provides binding to first detected IP
source; Address 255.255.255.255 accepts all peers, without binding. If
Lock IP is a multicast address, then the amplifier will accept queries sent
from any IP address of multicast group;

2.2.2.6 N+1 Control (Floating Master Mode)
This menu allows the user to set parameters relating to Floating N+1 Master operation.
This feature allows having a single point of control for an N+1 system Master Module.
When enabled, this mode will switch the N+1 Master Module serial and IP address to a
dedicated floating Master IP and serial address.
Without this function, a faulted Master Module in an N+1 system delegates its control
privileges to another unit, which has a different serial and IP address.
With this feature activated, the Master serial and IP address are reassigned to the new
Master Module and the former master unit restores its normal communication parameters.
This mode of operation allows having single M&C connection point bonded to a known
IP and Serial address, regardless which module in the N+1 system assumes the role of
the Master Module. In this mode, the user could maintain a remote connection to a single Master unit. Simultaneous connections to other modules is optional.
If Floating Master mode is disabled, the N+1 Master unit responds to its unique IP and
serial address rather than to a dedicated master address. In this mode, simultaneous
connection to all N+1 unit in the system is the most desirable method of remote control
operation.
Floating Master mode could be used over both RS-485 and IP network. Communication over a RS-485 network requires the assignment of a unique Master serial address.
The module currently assigned as the Master Module will also respond to queries on
its own serial address.
When this mode is used over an IP network, certain factors need to be taken in account:
•
•
•
•
42
The Master IP address must be a unique address, not used anywhere
else on the network;
Since Floating Master mode is assumed, the Master Module will stop responding on its individual IP address and start responding on Master IP
address. When the Master Module assumes slave mode (and another
unit is assigned the Master privileges), the former Master unit responds
to its individual IP address;
The Master address should be selected from same subnet mask and use
the same gateway address as the rest of the N+1 units in the system;
During the switchover process from a unit’s normal IP address and Master address and back, the SSPA unit will execute a “gratuitous ARP” request to a network. The operator needs to make sure that the network
202660 REV AB

•
equipment connected to the system supports dynamic ARP tables which
could be updated by “gratuitous ARP”. Consult your network administrator for details;
Floating Master mode needs to be disabled if network switches utilize
static ARP tables or if dynamic IP changes are forbidden.
Use of a dedicated serial Master address is optional, but desirable.

or simply show an alert on the front panel, the latter case considered a minor alarm.
• 1.Fault — This is the Major Alarm mode. Summary alarm on fault;
• 2.Alert — This is the Minor Alarm mode. No summary alarm on fault;
• 3.Switch Mute — In this mode, when the switch position changes, the
amplifier is momentarily muted during switchover to prevent arcing in the

202660 REV AB
High Power Outdoor SSPA Operations Manual
2.2.4.4 Fault Latch
Determines the alarm reporting condition. A latched alarm will remain indicated on the
front panel until the operator clears the alarm by pressing the Enter key. Unlatched
alarms will allow the summary alarm indicator to stop displaying the alarm condition if
the circumstance creating the alarm has been cleared or corrected.
2.2.4.5 Low RF / Automatic Level Control
Alerts the user when the output power falls below the threshold value, which is
adjustable by the user with 1 dBm steps by selecting the “Set Level” menu item. Fault
handling is adjustable by user, who may choose between Alert Only (Minor Fault),
Fault (Major Fault), and Ignore (No Fault tracking).
In addition, the user may select Automatic Level Control from this menu.
1. Select 3.ALC On and press the Enter key;
2. Select 5.Level;
3. Use the arrow keys to set the desired output level and press the Enter key.
Once activated, the ALC will take control of the amplifier’s attenuation setting to maintain the desired RF output power level and will not allow any attenuation adjustments
via the front panel. The ALC circuit will have the greatest ability to adjust for positive
and negative RF input level changes when the amplifier’s gain level is typically 65 dB.
By following the steps below, the optimum ALC RF input level can be set quickly.
1. Using the front panel menu, make sure the amplifier is not in ALC mode;
2. Set the amplifier attenuation level to 10 dB;
3. Apply a CW RF signal to the amplifier;
4. Use a power meter to measure the output power of the amplifier;
5. Adjust the RF input level until the desired output power level is achieved;
Follow the steps listed above to activate the ALC control. The ALC will take over the
control of the output level and maintain the RF output level set point.
The ALC has the ability to accurately control the RF output power over a 15 dB range
from Psat. The ALC will operate over a 20 dB range, but the accuracy of the last 5 dB
will suffer. For example, if the saturated power from the amplifier is 59 dBm, the lowest
accurate power setting during ALC control is 44 dBm.
If the output power set point is set outside the operational range of the ALC circuit, the
ALC will adjust the output power to the lowest possible level and set a minor fault on
the amplifier’s front panel.
Note: Automatic Level Control is inactive when the system is in N+1 operation.

2.2.5.6 Reset
Allows the user to reset the controller hardware to activate certain settings. For example, when the IP Address is modified, the unit must be reset to use the new address.
Firmware version 6.00 allows multiple reset levels for SSPA unit:
•
•
•
•
•
•
50
1.I/O Card — Resets all hardware on the removable M&C card as well as
the embedded cards on all RF modules. The amplifier will be Muted during the reset process. Hence, reset will cause a momentary loss of RF
output. All communication links to remote M&C will be dropped until reset
process is complete. The amplifier will use currently selected communication parameters (IP address, baud rate, etc);
2.I/O Card & RFModule — Resets only embedded chips in all RF modules. I/O card remains operational and maintains communication link to
remote M&C. The RF module will be muted during the reset process.
This function is useful for clearing latched fault conditions in SSPA units
under N+1 system control;
3.Coms only — Resets only communication parameters. If unmuted, the
SSPA maintains an unchanged RF output level during reset. Remote
COM links will be dropped and re-enabled with current parameters;
4.ClrFaults — Clears all latched faults and remaining fault history information. SSPA remains fully operational during the process;
5.MemMode — Allows alternate SSPA settings retention function. Two
choices are allowed:
○ RAM Mode — In this mode SSPA will not backup any settings changes to internal EEPROM. This mode is optional and needs to be set by
the user every time when SSPA endured power cycle or I/O card reset. This mode is beneficial when the SSPA application requires frequent changes to the SSPA state (such as mute/unmute or attenuation changes). Since any EEPROM device has limited write cycles,
RAM mode allows the user to execute unlimited settings changes. If
the SSPA experiences a power or reset cycle in RAM mode, it will use
the last saved settings setup before RAM was engaged;
○ EEPROM mode — Default SSPA mode. Without user intervention,
the SSPA will retain this mode of operation. All changes to settings
setup performed over local or remote interface will be backed up to
EEPROM within 3 seconds time interval. If the SSPA experiences a
power cycle or reset, the last saved set of settings will be applied to
the unit upon each power up or I/O card reset. Any EEPROM device
has a limited ability to endure write cycles. Maximum write cycles for
SSPAs with firmware version prior to 6.00 is 150,000. After exceeding
this limit, the SSPA will operate in RAM mode, utilizing a default set of
settings on each power up. Firmware versions of 6.00 and later allow
3,000,000 minimum write cycles before opting out to RAM mode;

array must be unique and with a contiguous N+1 address. Due to the architecture of
the weatherproof chassis, a single chassis utilizes one or two addressing units
(modules, typically addressed 1 and 2). For a system made up of two multi-module
weatherproof units, the second unit utilizes addresses 3 and 4.
The unit with the lowest N+1 address has the highest priority when the system selects
a new Master unit in the event of the failure of the assigned Master unit. A unit with Address 1 will be the default Master unit. If Unit 1 fails, Unit 2 will take its place as the
Master unit.

2.2.6.6.3 Auto Gain Control
This option allows the user to enable or disable the N+1 Automatic Gain options.
•
•
•
•
1.AutoGain 5dB — When Auto Gain is enabled, the system will automatically back off from maximum linear gain and reserve 5 dB of attenuator
range for gain compensation. When this option is enabled, the N+1 Master unit default System Information page will display: AutoGain(dB):XX.X
2.AutoGain Off — When Auto Gain is disabled, the system can be adjusted as if it was a single SSPA unit, attenuating system gain between 0
and 20 dBm. System gain will not apply automatic gain compensation if
any of the units in the N+1 redundancy array fails. When this option is
disabled, the Master unit default System Information page will display:
SSPAGain(dB):XX.X.
3.Keep Alive — The Keep Alive setting disables the automatic mute
function when a module enters a fault condition. This option may be beneficial in systems where the N+1 option is used only as a convenient single point of control, rather than as a redundancy control measure. Consult the factory on the use of this option.
4.Flex Gain — Flex Gain is a form of automatic gain control for N+1 systems. This control option has the same basic operation principles as the
standard Auto Gain option except that the gain reserves and amount of
gain compensation differ. This setting is designed to serve the special
gain compensation needs of hybrid PowerMAX SSPA systems.
When Flex Gain mode is enabled, the Master unit of the PowerMAX system automatically reserves a predetermined amount of attenuation to
each amplifier in the system and reduces overall system gain. In case of
one or more amplifier unit failures, the system will return a certain amount
of reserved gain in order to compensate system gain degradation from
the failed unit(s).
In the case of hybrid 4- and 2-way modes, the Master unit monitors the
amplifiers placed in standby mode and provides the proper amount of
gain compensation for these system configurations.

2.3 N+1 Operational Basics (single unit)
A single SSPA unit may be operated in N+1 mode in order to take advantage of the
Auto Gain Control features described in Section 2.2.6.6.3. In this case, each SSPA
module within the SSPA chassis is counted as a separate N+1 entity. For example, a
two-module 5RU chassis acts like a two-way N+1 array.
N+1 array indexing also accounts this type of functioning. Each 5RU chassis occupies
a segment of N+1 addressing equal to the number of modules; i.e., 2 modules = 2 addresses.
The remaining N+1 functions remain the same. When one of the internal modules develops a failure, it will be forced to mute by the internal SSPA controller. The unit will
develop a summary alarm, but will remain in N+1 master mode (if it was prior to failure). Multi-module units will delegate a new master mode only when all internal modules develop a failure.
Note: With multi-module RM SSPA chassis configurations, the N+1 system will require fewer chassis to form a N+1 redundancy array.
Examples of 4-way N+1 systems:
Two (2) two-module weatherproof SSPAs;
Four (4) one-module weatherproof SSPAs.
2.4 N+1 Operational Basics (two or more units)
A system which utilizes two or more weatherproof amplifiers in an N+1 configuration
may be operated directly from the front panel as if it was a single very high power
SSPA. Any weatherproof amplifier in the system can serve as the Master Module single point of control.
2.4.1 Selecting the Master Module
The selection of the Master Module is fully automatic and shifts from one SSPA to another based on the priority ranking assigned to the modules comprising each SSPA
unit. A lower priority index number (referred hereafter as the N+1 Address) means a
higher rank in the N+1 hierarchy. The fault-free unit with the lowest N+1 address is selected as the N+1 Master Module. The remainder of the units become N+1 Slave units.
Slave unit settings are under full control of the Master unit. Any system-related setting
change made on the Master Module automatically propagates to the Slave units to
keep all units under N+1 control in sync.
High Power Outdoor SSPA Operations Manual
202660 REV AB
55
If the Master Module develops any kind of major fault condition, it delegates its Master
privileges to the unit which is next in N+1 ranking and becomes a slave unit. This type
of control architecture eliminates a single point of failure and achieves true N+1 system
redundancy.
The Master Module is designated with a lit Online indicator and VFD display showing
the overall system state. See Figure 2-13.
Figure 2-13: Front Panel Display, Master Unit (Online indicator illuminated)
The Online indicators of the Slave units are always turned off and the VFD displays the
message shown in Figure 2-14.
Figure 2-14: Front Panel Display, Slave Unit (Online indicator dark)
Any unit that develops a major fault condition will be automatically muted to avoid any
side effects of the faulted unit on overall system performance.
The Master Module offers two extra informative menu screens for displaying system
level information such as: System forward and reflected power levels, system wide
gain or attenuation, amount of faulted SSPA chassis in the system, etc.
To avoid control conflicts, slave units are forbidden to gather system-wide information,
therefore these system wide information screens always hidden on N+1 Slave units.
2.4.2 Controlling System Operation
The N+1 system is under the control of the Master Module at all times. Any systemwide settings changes (local or remote) need to be performed on the Master Module. If
a setting is adjusted on a Slave unit, the Master Module will erase and override it with
the current system setting.
Some settings are not controlled by the Master Module because they are used for unit
identification or required for local adjustment during maintenance. Settings such as the
SSPA Network Address, N+1 Address, and IP Address are not enforced by the Master
Module and need to be set individually at every SSPA chassis.
The setting for enabling/disabling/sizing the N+1 system is also not controlled by the
Master Module. This setting allows the user to virtually remove individual SSPA units
from the N+1 control array for maintenance and troubleshooting.
56
202660 REV AB
High Power Outdoor SSPA Operations Manual
2.4.3 N+1 Addressing
During initial system installation, an appropriate N+1 address has to be selected for
each unit in the system. Each unit should be assigned a unique N+1 address. The valid addressing range is 1 to 16 for any type of system configuration. Address 0 is reserved for factory debugging and should not be used. Assigning an address higher
than the total number of SSPA chassis in the system (i.e., address 10 for a system
comprising four 5RU SSPA units) makes the unit thus assigned invisible to the Master
Module. The unit will continue to receive commands from the Master Module.
To set the N+1 address of a particular SSPA unit, press the Main Menu key; select
6.Redundancy and press the Enter key; select 6.N+1 and press the Enter key; select
2.N+1 Addressing and press the Enter key. Enter the desired address by using the
Left Arrow [◄] and Right Arrow [►] keys to increment the ones place and the Up Arrow [▲] and Down Arrow [▼] keys to increment the tens place.
The N+1 address order is not important for system operation. Assign the lowest address to the unit located most conveniently to the user. Subsequent addresses should
be assigned while keeping in mind the accessibility of the front panel controls.
See Section 3.2 for directions on changing the N+1 hierarchy of SSPAs in an active
system.
2.4.4 Adjust System Gain
Nominal system gain with Auto Gain enabled is 65 dB; nominal system gain with Auto
Gain disabled is 70 dB.
To adjust the gain of the system, press the Main Menu key; select 3.Operation and
press the Enter key; select 5.Attenuation and press the Enter key. Alternately, from
any of the System Information menus described in Section 2.3.1, press either the Left
Arrow [◄] or Right Arrow [►] key. Enter a value between 0 and 20.0 dB. If Auto Gain
is enabled, the system will reserve 5 dB of attenuator range for gain compensation and
attenuation is limited to a value between 0 and 15.0 dB.
2.4.5 N+1 Automatic Gain Control Option
Any modular hitless SSPA system may exhibit natural gain drift when one or more individual SSPA chassis is removed from the system or malfunctions. The automatic gain
control option allows the system to maintain a constant gain level during such events.
This feature is user selectable and can be activated from the SSPA front panel or a remote interface.
To toggle the Automatic Gain Control option, press the Main Menu key and select
6.Redundancy and press the Enter key; select 6.N+1 and press the Enter key; select
High Power Outdoor SSPA Operations Manual
202660 REV AB
57
3.Gain Control and press the Enter key. Select either Auto Gain On or Auto Gain Off.
When this option is activated, the SSPA will automatically reserve 5 dB of attenuator
range for future gain compensation. This will reduce the maximum SSPA gain by 5 dB.
The attenuator range will also be reduced to 15 dB.
Five dB of reserved attenuator range allows the system to fully auto compensate gain
when one SSPA module in a single 5RU SSPA unit enters a fault condition.
2.4.6 N+1 RF Power Measurements
The N+1 system may be equipped with a dedicated RF power measurement unit. The
RF Power Detector provides RMS measurement of Forward and Reflected RF power
directly at the output waveguide and this reading is acquired by the N+1 Master unit.
Besides N+1 system level power detection, each individual SSPA unit may be
equipped with its own RF power detector. This reading can be viewed at each SSPA
unit and may be used for troubleshooting individual SSPA units.
To view the RF power detector reading on the front panel, press the Main Menu key,
select 1.SysInfo and press the Enter key; press the Down Arrow [▼] key to get to
Sys Info Page 1.
2.4.7 N+1 Fault Detection
The N+1 system carries comprehensive fault detection logic. Each SSPA chassis processes its internal fault conditions as if it was a standalone unit. All N+1 Slave units report any fault state to the Master Module, which is responsible for system wide fault
state handling. Failure of any single SSPA unit leads to a minor N+1 alarm on the Master Module. This type of fault condition will not produce a summary system alarm.
The user may view the number of faults in a system from the front panel by pressing
the Main Menu key of the Master Module; press the Up Arrow [▲] key to get to N+1
Master Info Page 2. Any detected SSPA unit alarms present in the system will be displayed at the “N+1 Alarms” screen.
If the Master unit detects two or more failed units, it will report a system-wide Summary
alarm (Summary alarm LED on the Master unit will illuminate). The cause of the alarm
will not be evaluated by the Master Module. To find cause of the failure, the operator
will need to evaluate the local fault conditions of the failed SSPA unit.
58
202660 REV AB
High Power Outdoor SSPA Operations Manual
2.5 Reflected Power Option
When this option is installed, the user may measure the amount of reflected RF power
present at the amplifier’s output flange, with a dynamic range of 12 dB starting at the
maximum RF output.
For example, an amplifier with 50 dBm (100W) of maximum forward RF would be capable of reading reflected power levels from 38 dBm (6W) to 50 dBm (100W). The
amount of reflected power can be viewed on the Front Panel Display screen:
1. Press the Main Menu key on the front panel;
2. Select 1.SysInfo and press the Enter key.
Note: All Teledyne Paradise Datacom SSPAs are protected from shortterm 100% reflected power conditions. Teledyne Paradise Datacom does
not recommend operating the amplifier under a sustained condition of
100% reflected power. The addition of the reflected power sensor option
allows the operator to monitor the amount of reflected power on the amplifier for the purposes of identifying issues with the transmission signal.
The user may set up a Major Alarm trigger for High Reflected Power conditions in the Teledyne Paradise Datacom Universal M&C software. This
alarm only indicates the presence of the high reflected power condition,
and will not alter the amplifier settings to compensate for the condition.
2.5.1 Reflected Power Alarm
Because the reflected power circuitry is not a true VSWR measurement, but simply a
measure of absolute reflected power, it is possible to set an alarm level. In units with
the reflected power monitor option, the alarm level is factory pre-set as a major alarm
at 80 percent of the amplifier’s rated power.
For example, an amplifier with 50 dBm (100W) of output power would have an alarm
level set to 49 dBm (80W).
Note: Teledyne Paradise Datacom does not recommend changing this
setting from the factory pre-set due to possible frequent false alarms that
may be generated if set at a much lower level. However, it is possible to
adjust the setting in the Universal M&C software.
High Power Outdoor SSPA Operations Manual
202660 REV AB

2.5.2 Reflected Power in S-Band Units
In S-Band units outfitted with this option, the reflected power monitor measures
amount of reflected power seen by the HPA and is not a VSWR monitor. The HPA
begin to display reflected power when it reaches a level of 47dBm. In the event
reflected power measures > 51dBm the HPA will show a summary alarm to alert
user about the reflected power issue.
the
will
the
the
If the reflected power reaches 52dBm, the HPA will begin to fold-back the forward RF
power. This will prevent any damage to the HPA that a high reflected power could
cause when the HPA is being operated at high forward RF levels.
The term “fold-back” refers to the amplifier being power limited in its ability to generate
more output power once the reflected power reaches a level that is potentially damaging. The amplifier is not muted during fold-back. See Figure 2-15.
Figure 2-15: Power Limiting at High VSWR Levels
The reflected power can be monitored using the Universal M&C software, as well as
via the local display on the HPA.

Section 3: Troubleshooting and Maintenance
3.0 Troubleshooting Faults
The High Power Outdoor SSPA has five fault condition LEDs on left
side of the local control panel (located inside the hinged front cover)
which reflect a summary fault, and fault states for voltage, temperature,
current and the amplifier’s power supply. Additional fault reporting is
available via the local control panel LCD readout or via the Teledyne
Paradise Datacom Universal M&C Software. Figure 3-1 shows a
representation of the fault condition indicators.
The following sections describe steps the user should take to determine
the cause of a fault state in a stand-alone amplifier.
Figure 3-1:
Fault
display
3.0.1 Fan Fault
In the case of a fan fault, follow the tips below:
• Inspect the fans.
• The user should check the booster board voltages on the local control
panel. This can be found under the system information portion of the
main menu. The voltage should read approximately 28VDC for each of
the fans in the SSPA.
• If necessary, replace the fan (See Section 3.1.1).
3.0.2 Summary Fault
Any of the following faults also results in a summary fault state.
3.0.3 Voltage Fault
The user should check the voltages displayed on page 6 of the system information
menu of the local control panel display. If the voltages are outside of the normal output
ranges as described in Section 2.2.1.6, consult the factory.
3.0.4 Temperature Fault
If you are experiencing a temperature fault, follow the steps below:
• Check the ambient air temperature of the room where the SSPA is installed. Check the environmental specifications on the specification sheet
for your SSPA. If the ambient temperature is beyond these limits the amplifier may experience a temperature fault. If this is the case, the ambient
temperature will need to be brought into the specified range.
• If the ambient temperature is within the specified range and the amplifier

•
•
still experiences a temperature fault, the user should first perform a visual
inspection of the fans to make sure they all appear to be operating.
The user should check the front panel read-out out for a fan fault. This
can be found under the system information portion of the main menu on
the front panel. If a fan fault is present, the user may need to replace the
fan that is not functioning.
The operator should check the booster board voltages on the front panel
display. This reading can be found under the system information portion
of the main menu on the front panel. The voltage should read approximately 28 VDC for each of the fans in the SSPA. If the booster voltage is
lower than 25 VDC, the operator should check for a power supply fault
and follow the procedures to handle this problem.
3.0.5 Current Fault
In the case of a current fault, follow the tips below:
• The user should check the current displayed on page 6 of the system information menu of the front panel display. If the amplifier is in the mute
state, current drops within a range of 0 to 5 A.
3.0.6 Power Supply Fault
In the case of a power supply fault, follow the steps below:
• When using an external power supply with the amplifier, verify that all
power supply modules are operating normally. Replacement power supply modules are available through technical support.
• Check the power supply readings on the SSPA front panel. Observe any
fluctuations and record the level.
• Mute the amplifier. Check the power supply readings on the SSPA front
panel. Sometimes muting the amplifier corrects the power supply fault.
• Check the DSUB (alarm) cable that connects between the SSPA and the
external power supply. If this cable is pulled or making poor contact, this
may cause a false power supply alarm.
• Note that the amplifier M&C logic is designed to mute the amplifier is
more than one power supply module faults. If the DSUB power supply
alarm cable is removed, the amplifier will continue to operate but will
show a persistent power supply fault.
3.0.7 Low RF Fault
In the case of a Low RF alarm, follow the steps below.
• Check the forward RF level on the local control panel readout under the
system information menu. If the user has access to a power meter or
spectrum analyzer, this power level can be verified by means of the output sample port on the front panel.
• Compare this value to the forward RF alarm threshold level in the Fault
62
202660 REV AB
High Power Outdoor SSPA Operations Manual
•
•
Set-up menu. If the Threshold level is higher than the actual RF output
level, this will produce a low RF alarm, providing that the low RF alarm
option is enabled.
Be sure that the forward RF alarm threshold level is set to a value corresponding to the desired output level for the SSPA in question. The factory
pre-set for this value is always 10 dBm below the specified P1db compression point of the SSPA. You may wish to set this level closer to the desired output level in order to catch any minor fluctuations below the set
level. If the level is set too high, the low RF alarm may be displayed when
there are no legitimate problems. If the RF input signal is lowered, this
will also lower the output of the SSPA and may cause a low RF alarm.
If the user is certain that the amplifier is in an alarmed state due to problems other than the ones stated above, the user should verify that no other fault conditions are present. If a power supply fault, current fault, or
voltage fault is present, this may also cause the low RF alarm to show. If
any of these is the case, the user should refer to the sections corresponding to that specific fault.
3.1 Modular SSPA Architecture

To remove this card assembly, loosen the two restraining thumbscrews at the top left
and bottom right of the assembly. See Figure 3-6. Slide the assembly forward out of
the cavity. This exposes the SSPA module programming connectors. See Figure 3-7.
The DigiCore5 controller card is equipped with a configuration DIP switch block, S1.
This switch allows the adjustment of certain configuration parameters.
• S1.1 - S1.6 — Factory use only; Preset position is ON-ON-ON-OFFOFFOFF;
• S1.7 - S1.8 — These settings allow Enable/Disable galvanic isolation of
the Main serial port (J4). Factory preset for these ports is OFF – OFF.
This configuration disconnects the Serial Main Ground pin from the chassis ground. If, for any reason, the galvanic ground isolation is not desired,
this feature could be disabled by changing the position of switches S1.7 –
S1.8 to ON – ON.
Warning! Disabling galvanic ground isolation increases the risk of
serial port electrical damage during a lightning strike, or under other ground potential difference issues. If galvanic isolation is disabled, Teledyne Paradise Datacom suggests connecting or disconnecting the wire harnesses to this port only when the equipment is
powered down.

3.2 Periodic Maintenance
While the Teledyne Paradise Datacom High Power Outdoor SSPA has been designed
to operate in the most adverse conditions, regular maintenance is still required. The
fans and heatsink must be cleaned periodically. Failure to keep the fans and heatsink
free of debris will void your warranty.
3.2.1 Intake and Exhaust Fans
Make sure the intake and exhaust fans of the amplifier are kept clear of debris so that
air can flow unimpeded into the enclosure. Periodically clean the screens covering the
intake fans at the bottom of the amplifier by using compressed air to clear away any
obstructions.
See Sections 3.1.1 and 3.1.2 for instructions on accessing the fans.
Should a fan need to be replaced, contact Teledyne Paradise Datacom for a fan
replacement kit. Order L203152-1 for the Intake Fan Kit or L203152-2 for the Exhaust
Fan Kit.
3.2.2 Heatsink
Dust and debris may become lodged in between the fins of the heat sink during normal
operation. Over time, this debris may accumulate and reduce the ability of the heatsink
to transfer heat away from the internal module. Therefore, it is important to periodically
inspect the heatsink fins and clear away any debris.
Access the heat sink by removing the intake fans at the bottom of the amplifier, as
described in Section 3.1.1. Using compressed air, blow through the SSPA heat sink to
remove any foreign object accumulation that may be obstructing airflow over the fins.
Replace the intake fans and fan screen.
3.2.3 Access Door Gasket and Locking Mechanism
The High Power Outdoor SSPA features a hinged door with two locking latches that
seal the local control panel other sensitive electronics from the environment. The door
is sealed against the environment with the use of a heavy rubber gasket. Inspect this
gasket periodically for tears or signs of leakage, and replace if necessary.
Make sure that there is even pressure around the door gasket when the door is closed
and fully latched. The tension on the door latches can be adjusted by loosening or
tightening the adjustment nut on each locking latch, as shown in Figure 3-15.
High Power Outdoor SSPA Operations Manual
202660 REV AB

3.2.4 Connector Weatherproofing
As a precaution, all cable connections should be wrapped with weather-resistant
electrical tape, provided with the unit. Make sure each connector is clean and dry
before applying the electrical tape.
Apply electrical tape to all circular MIL type connectors, N-type connectors and any
joins in the semi-rigid coaxial cables. Starting at the cable end, wrap the weatherresistant electrical tape around the connector, overlapping each turn by half the width
of the tape. Continue wrapping until the connection mating point is enveloped. Wrap an
extra turn around the base of the connector. Press and smooth the tape with your fingers to form a good seal. The tape surface should be uniform in appearance with no
visible gaps or protrusions.
The Ethernet Port (J9) on the High Power Outdoor amplifier is shipped with a mating
cap and a mating connector to be used with a Cat5 Cable for applications utilizing
communication via Ethernet. The mating cap of the connector fastens securely to the
Ethernet Port by means of a bayonet lock. Failure to ensure a tight connection may
result in water leakage through the connector.

High Power Outdoor SSPA Operations Manual
3.3 Changing N+1 Hierarchy
Normally, the hierarchical structure of the N+1 array must be set during initial system
setup. However, the operator may change the N+1 addressing hierarchy at any time.
To ensure uninterruptible system operation during such system maintenance, certain
procedural steps must be followed.
3.3.1 Changing Hierarchical Order of Slave Units
To change the hierarchical order of N+1 slave units without interrupting the system
operation:
Important! The Master unit will lose sight of one of the slave units for the
duration of this procedure. If the system is in Auto Gain mode, this condition will cause gain overshoot. Temporarily turn off the Auto Gain feature.
1. Turn off Auto Gain setting if needed.
2. For the first slave unit, temporarily select an N+1 address setting outside the
maximum address for the current N+1 array. For example, in a system of
4 units, select address 5 or above; for a system of 8 units, select address
9 or above; etc.
3. For the second slave unit, change its N+1 address to match the previous
N+1 address of the first unit.
4. Change the N+1 address of the first slave unit to match the previous N+1
address of the second unit.
5. System addressing hierarchy is now exchanged between first and second
unit. Turn on Auto Gain option if required.
3.3.2 Exchange N+1 Privileges Between Master and Slave Units
To delegate master privileges to a slave unit without interrupting system operation:
1. On the slave unit intended to be set as new Master unit, set the N+1 address
value to “0”. Assuming the unit is free from internal faults, the unit will
instantly change its mode to Master.
2. On the former Master unit, select its N+1 address to match the address of
the former slave unit.
3. On the new Master unit, change the N+1 address value from “0” to the
address value of the former Master unit.
3.3.3 Add SSPA Unit to the System
If one of the SSPA units was removed from the system or it down for maintenance,
adding it back to system array may cause an unexpected change to a system state. To
provide uninterruptible system operation, follow the procedure below.
High Power Outdoor SSPA Operations Manual
202660 REV AB
73
1. Locate the current Master unit and change its N+1 address value to “0”;
2. If the new unit has an unknown N+1 address or has not been configured for
N+1 operation, turn off the Auto Gain option;
3. If the new unit has a known N+1 address in conflict with one of the current
SSPA slave units, resolve it by changing address of the current Slave unit.
4. Add new unit to system. Make sure newly added unit assumed N+1 slave
mode. Make sure current Master unit doesn’t detect any N+1 faults.
5. Change Master unit N+1 address from value “0” to it’s previous value.
6. Follow Scenario 1 and 2 if hierarchical order change is required.
3.4 System Gain and Power vs. Number of Modules in System
With parallel system architectures the amplifier output power capability and gain will
change as the number of active modules varies. The High Power Outdoor SSPA is
designed so that the overall system gain will remain constant in the event of a single
module failure. This is achieved when the system is operated in “Auto-Gain Control”
mode (See Section 2.4.5).
Figure 3-16 shows the system gain and maximum output power for a 6RU SSPA
chassis with a failure in one, two, and three SSPA modules within a single chassis.

High Power Outdoor SSPA Operations Manual
Section 4: Redundant System Operation
4.0 1:1 Redundant Systems
This section describes how to configure and control a 1:1 redundant system, which
consists of two Teledyne Paradise Datacom High Power Outdoor SSPAs and a waveguide/coaxial switch.
Two SSPA units can be connected in a 1:1 redundant configuration, which can automatically switch to an operating amplifier if the on-line SSPA develops a system fault.
In order to work in redundant mode, both SSPAs must be properly configured and interconnected. Because both SSPAs have a microprocessor unit, an additional controller is not required.
Two amplifiers can be connected to each other and to a waveguide/coaxial switch.
One of the amplifiers is designated as “on-line”; the other is designated as “standby”.
The on-line SSPA receives the input RF signal and transmits an amplified RF signal to
the RF load. The output of the standby SSPA is terminated at the dummy load. Figure
4-1 shows a block diagram of a typical 1:1 Redundant System.
Figure 4-1: Block Diagram, 1:1 Redundant System
Two modes are available for the standby SSPA: “Hot” or “Cold” standby. An SSPA in
“Hot” standby mode remains fully operational (the preferred method). An SSPA in
“Cold” standby mode remains muted when off-line. This mode is only used where
prime power conservation is critical. The normal factory default for redundant systems
is “Hot” standby mode.
When the system is in “Auto” mode, if a summary fault develops in the on-line amplifier, its state will be sensed by the standby SSPA through the link cable. If the standby
SSPA is in a non-faulted state, it will force the waveguide switch to reposition and put
itself into the online state. The process typically takes no more than 200 ms.

High Power Outdoor SSPA Operations Manual
Both SSPAs constantly monitor the waveguide switch position. The proper position for
the online SSPA is determined by the “Unit Status” setting. If the selected SSPA is
configured as “HPA1,” it will drive the RF switch to Position 1 to set itself to the on-line
state. Selecting unit status to “HPA2” will configure that SSPA to drive the switch to
Position 2 for the on-line state. In “Auto” mode, the online SSPA will make two
attempts to force the switch to take proper position, before accepting its new state.
4.1 Hardware
Two High Power Outdoor SSPA units are used for a 1:1 redundant configuration. The
units are connected to each other through a link cable, which allows the exchange of
online/standby status between SSPAs.
Both SSPA units are connected to the waveguide switch through a Y-cable. This
allows either amplifier to drive the switch to its proper position. Each unit must be
configured with a unique identity. If one SSPA is configured as “HPA1”, the other
should be configured as “HPA2”. Both SSPAs must be set to 1:1 Redundancy mode.
Figure 4-2 shows an outline drawing of a 1:1 Redundant System.
4.1.1 Switch Power Supply
Each SSPA may contain up to two 28V (depending on the power level of the SSPA)
power supplies, to supply power to the waveguide switch. The state of the 28V power
supplies (referred as “Boost1” and “Boost2”) can be monitored from the SSPA control
panel LCD and through remote serial protocol. Power supplies are fully protected from
over-current and over-voltage conditions and can reliably output up to 3 A of DC
current.
4.1.2 RF Switch
The SSPA redundant system controls a -28V waveguide/coaxial switch using the 6-pin
rear panel connector J3. The switches are controlled by applying +28V to the common
of the switch and pulsing either position to the ground. The system then verifies the
position of the switch.
4.1.3 Switch Connector
The 6-pin connector J6, MS Connector P/N MS3112E10-65, can be located on the
SSPA connector panel. This connector is used to interface with the RF switch.
Teledyne Paradise Datacom recommends the use of following parts to build a mating
pair to this connector: MS3116F10-6P.
Table 4-1 shows the proper wiring to the MS3116F10-6S RF switch connector,
commonly used on waveguide switches. Figure 4-3 shows an outline drawing of a
typical switch connector cable.

4.2 Installation and SSPA configuration
Two High Power Outdoor SSPA units are designed to be installed on a uni-strut rack
provided by Teledyne Paradise Datacom. See the High Power Outdoor 1:1 Redundant
System Mounting Kit manual (document number 203187) and the system drawing
package for details on proper mounting procedures.
4.2.1 Configuring Amplifiers to work in 1:1 redundant mode
Proceed with the following steps to configure the system to work in 1:1 redundant
mode.
4.2.1.1 Setting SSPA1 to work in 1:1 mode [1:1/1:2 Redundant or Single Thread]
1. From the control panel of SSPA1, press the “Main Menu” key;
2. Select item “3. Operation” and press “Enter” key;
3. Select item “5. Sys.Mode” and press “Enter” key;
4. Select item “2. 1:1 Mode” and press “Enter” key;
4.2.1.2 Setting SSPA1 switching mode [Automatic or Manual]
1. From the control panel of SSPA1, press the “Main Menu” key;
2. Select item “6. Redund.” and press “Enter” key;
3. Select item “1. Switching” and press “Enter” key;
4. Select desired SSPA switching method and press “Enter” key.
Note: The second SSPA must utilize the same switching method as
the first.
4.2.1.3 Setting SSPA1 unit status [HPA1 or HPA2 designation]
1. From SSPA control panel press the “Main Menu” key;
2. Select item “6. Redund.” and press “Enter” key;
3. Select item “4. Status” and press “Enter” key;
4. Select item “1. HPA” and press “Enter” key.
Note: SSPA2 unit status must be set to HPA2.
4.2.1.4 Setting SSPA1 standby status [“Hot” or “Cold” Standby]
1. From SSPA control panel press the “Main Menu” key;
2. Select item “6. Redund.” and press “Enter” key;
3. Select item “3. Standby Mode” and press “Enter” key;
4. Select item “1. Hot Standby” and press “Enter” key.
Repeat steps 4.2.1.1 through 4.2.1.4 for SSPA2.

4.2.2 Online / Standby Amplifier Selection
To instantly determine the on-line state of a particular SSPA, the “Unit 1” button on the
control panel keypad (See Figure 4-5) should be illuminated. To put the SSPA in
standby mode, press the “Unit 1” key and the light should go off. If the system is in
“Auto” mode, the second SSPA will accept the on-line state only if there is no summary
alarm.
Figure 4-5: “Unit 1” Indicator from Control Panel
The “Unit1” LED on the second SSPA will illuminate, indicting it is on-line and rotate
the waveguide switch to the correct position. If the second SSPA does not accept the
on-line state, the first SSPA will revert to the on-line state after 1 second.
Note: Only the on-line SSPA can be switched to standby. The reverse process,
switching the standby SSPA to the on-line state, will not work.
In manual mode, the standby SSPA will always accept the on-line state regardless of
its own fault status. The user can verify the state of the waveguide switch by browsing
to informative screen [3] on the control panel LCD. Item RFSW1 will indicate the state
of the waveguide switch, as detected by the SSPA. If the switch position can not be
detected; “Fault” will be displayed.
4.2.3 Auto versus Manual Switching Mode
Normal operation mode for a High Power Outdoor SSPA in 1:1 redundant
configuration is “Auto”. This mode provides automatic detection of an SSPA fault and
switchover to the operational SSPA. The system is also protected from operator errors;
selecting a faulted SSPA is not allowed. In situations when system maintenance must
be performed, “Manual” mode should be used. In “Manual” mode, the operator can
select the on-line and standby SSPA by pressing the “Unit1” key. The system will not
provide automatic switchover to a faulted SSPA, but rather will keep the selected
SSPA online, regardless of its state.
Note: In order to function normally, both SSPAs must utilize same switch mode.
4.2.4 Physically Rotating Transfer Switch
It is possible to physically rotate the shaft on the transfer switch to change the online
and standby amplifiers positions. This can be done either in manual or automatic
mode. When the switch is physically rotated in automatic mode the online SSPA will
attempt to return the switch to its previous position. The SSPA will make two attempts
to return the switch before accepting the new position.

High Power Outdoor SSPA Operations Manual
4.2.5 Switchover Muting [TX Disable Before Switch Mode]
In certain RF systems, it is desirable to disable the RF before activating a redundant
switch. This can eliminate potential RF arcing in the transmission system. RF arcing is
generally only problematic in waveguide systems with output power levels greater than
1 kW or with certain coaxial switches where switch contacts may be sensitive to arcing.
The normal factory default disables the switchover mute mode. This mode relies on the
switch position information. This means that any failure to the switch position detection
circuitry, wiring harness, etc., will cause the RF output power to mute. Therefore the
switchover muting mode is only recommended in those RF systems that absolutely
require RF disabling.
To enable switchover muting from the SSPA Front Panel:
1. Press the Main Menu Key;
2. Select item “4.Flt.Setup” and press the “Enter” Key;
3. Select item “3.RF Switch” and press the “Enter” Key;
4. Select item “4.MutedSwitch” and press the “Enter” Key

4.3 1:2 Redundant Systems
This section describes how to configure and control a 1:2 redundant system, which
consists of three High Power Outdoor SSPAs and a waveguide/coaxial switch
assembly.
Three SSPA units can be connected in a 1:2 redundant configuration. The standard
1:2 configuration has HPA1 online in the polarization 1 path, HPA3 online in the
polarization 2 path, and HPA2 acting as spare backup for ether HPA1 or HPA3. Figure
4-6 shows a block diagram of a 1:2 system.
Figure 4-6: Block Diagram, 1:2 Redundant SSPA System
A 1:2 redundancy system normally requires a separate redundancy controller (RCP).
The RCP is used to constantly check the state of the controlled HPAs and, in case of
malfunction, rotate the waveguide switches according to an internal logic table.
Operation of a 1:2 system with controller is more fully discussed in the Redundant
Systems Controller Operations Manual, document number 205933.
High Power Outdoor SSPA Operations Manual
202660 REV AB
83
4.3.1 1:2 Redundant Systems with L Band Input
A 1:2 Redundant System with L-Band Input can be configured with internal Block Up
Converters that contain internal 10 MHz reference oscillators or configured for use with
an external 10 MHz reference source. Systems configured with internal 10 MHz
reference are straightforward extensions of the basic 1:2 architecture. Because the 10
MHz reference is integral to the converter there is no possibility of an interruption of the
10 MHz during switchover. Furthermore the standby amplifier always has 10 MHz
reference and will not be faulted. Such a system is shown in Figure 4-7.
Figure 4-7: 1:2 Redundant System with L-Band Input and internally referenced
Block Up Converters (BUCs)
The Block Up Converters used in Satcom equipment typically use some form of phase
locked local oscillator in the converter architecture. The Block Up Converter will signal
an alarm condition whenever the oscillator looses phase lock. The amplifier will go into
a mute state so that no spurious (off frequency) emissions can be transmitted to the
satellite. The alarms from the BUCs and SSPAs are sent to the RCP2-1200 system
controller which determines the proper switch conditions for the system.
A special case of the 1:2 Redundant System exists when an external reference is
required of the system. With an external 10 MHz reference input on each polarity input
to the system, the standby amplifier will not receive a reference signal and therefore
would be in a faulted condition. In this state, the redundant controller will not allow the
standby amplifier to come on-line if a failure occurs with HPA 1 or HPA 3. See Figure
4-8.
84
202660 REV AB
High Power Outdoor SSPA Operations Manual
Figure 4-8: 1:2 Redundant System with external reference, showing
lack of 10 MHz reference to Standby BUC
At first it may be thought that a 10 MHz signal could be injected into the normally
terminated port of the input switches. While in a normal operating state with all three
BUCs operational this would work fine. However in the event of a failure of one of the
on-line units, the 10 MHz would also be interrupted to the standby unit, as shown in
Figure 4-9. Due to the quick determination of a unit fault, the controller will interpret a
fault on the standby amplifier and reliable switchover can not be guaranteed.
Figure 4-9: 1:2 System with (3) 10 MHz inputs through the input switches.
The reference to the standby unit is interrupted during switchover.
High Power Outdoor SSPA Operations Manual
202660 REV AB
85
To overcome the problems that result from interruption of the 10 MHz reference, it is
imperative that the reference be injected in the system after the waveguide switches.
One technique could be to install a multiplexer on the input of each amplifier that would
allow the injection of the 10MHz reference. In this case a separate 10 MHz line would
have to be run to the system and a three-way splitter could distribute the reference to
each amplifier.
The standard Teledyne Paradise Datacom configuration overcomes this issue by using
a Reference Combiner assembly. See Figure 4-10.
Figure 4-10: 1:2 Redundant System with External 10 MHz Reference using
a Reference Combiner Assembly
The Reference Combiner assembly couples a sample of the 10 MHz reference from
each of the two polarity inputs. It will then supply the standby amplifier with the
reference from either of the two inputs. The reference combiner arbitrates which
10 MHz signal to supply to the standby amplifier. It will not supply both 10 MHz
sources to the standby amplifier. This allows all three amplifiers to be in a normal
operating (non faulted) condition and the RCP2-1200 controller can operate the
system in normal 1:2 redundancy. This eliminates the need for a separate 10 MHz line
going to the system as the 10 MHz reference normally exists on each L-Band cable.
Amp 2 is meant to be the standard stand-by amplifier in this configuration. Should Amp
1 or Amp 3 fault, the RCP2-1200 will automatically switch to Amp 2. However, when
this occurs, this interrupts the 10 MHz reference to the faulted Amp/BUC, which results
in a constant BUC fault on that thread. In order to return Amp 2 to the stand-by state,
the user will need to clear the fault, switch to manual mode on the RCP2-1200 and
then select Amp 2 as stand-by. Table 4-4 gives a step-by-step guide to returning Amp
2 to stand-by status.

Three High Power Outdoor SSPA units are used for a 1:2 redundant configuration. The
units are connected to each other through a link cable, which allows the exchange of
online/standby status between SSPAs.
Each SSPA unit is connected to the waveguide switches through a E-cable. This
allows either amplifier to drive the switch to its proper position. Each unit must be
configured with a unique identity. If one SSPA is configured as “HPA1”, the others
should be configured as “HPA2” and “HPA3”. Each SSPA must be set to 1:2
Redundancy mode. Figure 4-11 shows an outline drawing of a 1:2 Redundant System.

4.4.1 1:2 Redundant System Switching
A RCP2-1200 Redundant Control Panel is required in any 1:2 redundant system. The
controller monitors the condition of each SSPA and controls the position of the waveguide switches based on the internal logic table pre-configured for the system.
Communication throughout the system is handled via a series of cables, one set from
the RCP unit; another set from the SSPAs and the switches.
4.4.1.1 RCP2 to Switch Plate Cable (L201061)
This cable is the primary switch control cable, and connects at P1 to port J3 of the
RCP2-1200 and at P2 to the system interface panel, where it connects to the Switch

4.6 1:2 Operation with Internal Redundancy Control
A 1:2 redundancy system normally requires a separate redundancy controller (RCP).
Teledyne Paradise Datacom also offers an internal 1:2 redundancy system, where the
extra controller is not required and the state of the system is negotiated between all
three HPAs over the redundancy link and switch cables. In this system, the link cable is
used to pass information regarding the standby/online state between the HPAs. The
switch cable is used to drive waveguide switches and determine their current position.
The system current state is determined by the position of the two waveguide switches.
Each HPA constantly monitors the state and assumes an online or standby state from
the switch position. All three HPAs need to be configured to “HPA1”, “HPA2” and
“HPA3” status according to their relative position to the waveguide switches. These
settings need to be provided to each HPA by the operator through the HPA front panel
menus or through a remote control interface.
The system is capable of operating in two modes: “Auto” and “Manual”. Normally, the
system needs to be configured in “Auto” mode. In this mode, when an HPA develops a
summary alarm, the system will automatically switch to the backup HPA. “Manual”
mode should be used only for maintenance purposes. During this mode, automatic
switchover will be performed if a malfunctioned HPA’s controller card is completely
dead. If an HPA has a summary fault, but the controller card is still alive then HPA will
remain in online state.
Both modes allow the user to switch HPAs from online to standby state by pressing
“Unit1” button on the front panel or through command on remote interface. Typical
switchover time is 200mS or less. Switchover also can be performed by physical
rotation of one or both waveguide switches. Unlike internal 1:1 redundancy mode, the
SSPA will not prevent the operator from turning the switch.
4.6.1 Required Hardware
•
•
Three SSPAs with controller card firmware revision better than 2.50 and
I/O card version better than 1. Internal 1:2 redundancy mode for earlier
hardware/firmware revisions is not available. If you purchased your SSPA
as a standalone unit or as part of a 1:1 system, consult with the factory to
determine if the revision of digital controller is 1:2 enabled. 1:2 redundancy Mode, unit HPA status and polarization priority need to be selected on
all connected HPAs.
1:2 Link Cable. The link cable allows redundancy state information to
pass between the HPAs and should be connected to the Link Port, J8.
Important! Cable ends are not symmetrical! When connecting HPAs with
the link cable make sure that connected units HPA status (HPA1, HPA2 or
HPA3) match the labels on the link cable ends!

The 10-pin male connector J4 Link Port, MS3112E12-10S, is used to link an HPA with
the two other redundant units in order to pass online/standby status information
between them. The link cable is an asymmetrical crossover cable. Take care to match
the labels on each cable with the HPA status of the units (i.e., plug cable end with label
“HPA1” into the SSPA with selected “HPA1” status, etc).
Warning! Do not remove this cable while the system is in operation! The system
will not operate properly.

Section 5: Phase Combined Systems
5.0 Phase Combining Overview
Phase combining amplifiers has long been a popular means of increasing the output
power of an amplifier system. Under high power microwave conditions it is common to
utilize some form of waveguide hybrid coupler to combine the output power of two
amplifiers. This coupler is generally a waveguide tee such as a four port magic tee. On
the input side, common coaxial power splitters can be utilized to divide the power due
to the lower power levels at the input of the system.
Figure 5-1 shows a typical block diagram of a phase combined amplifier pair. As long
as the electrical delay, phase and amplitude of the two paths are kept within close
tolerance of each other, the output power of the system will be twice the output power
(+3dB) of a single amplifier.
Figure 5-1: Phase Combined Amplifier System
The main drawback of this approach is that in the event of an amplifier failure, the total
output power decreases by 6 dB, or a factor of 4. This does not offer the system much
in the way of redundant capability with such a large decrease in output power capability. The power decrease is due to the fact that with only one amplifier active, the output
combiner acts as a power divider. The output power from the remaining amplifier is divided between the output of the system and the terminated port of the hybrid combiner.
Thus only half of the power from one amplifier reaches the output port which is 6 dB
less than the combined output power from both amplifiers.
A high power system requiring a degree of redundancy needs some means of bypassing the combiner in the event of an amplifier failure. This would allow the full output
power capacity of the remaining amplifier to reach the output.
High Power Outdoor SSPA Operations Manual
202660 REV AB
97
In this case the total RF output power would only decrease by 3 dB from the phase
combined output power. A 3 dB reduction in output power is generally more tolerable
to a system’s link budget thereby giving the system a degree of redundancy.
A technique has been developed which accomplishes phase combining and provides
redundancy with two waveguide transfer switches. A block diagram of such a system is
shown in .
Figure 5-2: 1:1 Fixed Phase Combined System with FPRC-1100 controller
This type of system is sometimes referred to as a “Fixed Phase” combined system to
differentiate it from the Variable Phase Combiner (VPC) systems commonly used with
Traveling-Wave Tube Amplifiers. In the 1:1 Fixed Phase Combined system, the waveguide switches allow the amplifier outputs to either be directed into the combiner or bypass the combiner and connect directly to the RF output.
Teledyne Paradise Datacom has developed a series of controllers that greatly
enhances the operation of the phase combined system. The FPRC-1100 Phase
Combined System Controller is designed specifically to control 1-for-1 Fixed Phase
Combined redundant amplifier systems. The FPRC-1200 Phase Combined System
Controller allows remote control of 1-for-2 Fixed Phase Combined redundant amplifier
systems.
98
202660 REV AB
High Power Outdoor SSPA Operations Manual
Each controller can be used in either manual or automatic mode to monitor the system
amplifiers for faults and operate the transfer switches. The controller has a very user
friendly interface that allows the operator to monitor the composite output power of the
system and adjust the gain of the amplifiers in 0.1 dB increments over a 20 dB range.
The controller adjusts each amplifier in the system and keeps the amplitude of each
balanced for optimal power combining. To the operator, the system appears as a
single amplifier. The operator can choose between using the system as a phase
combined system or a traditional redundant system.
5.1 1:1 Fixed Phase Combined System Components
A 1:1 Fixed Phase Combined Amplifier system consists of:
(1) Amplifier Base Assembly, which comprises:
(1) Mounting Frame Assembly
(2) High Power Outdoor SSPAs
(1) Waveguide Switch Assembly
(1) Signal Box Assembly
(2) Cable Assemblies between SSPAs and Signal Box
(1) FPRC-1100 1:1 Phase Combined Redundant Controller
(2) Cable Assemblies between Signal Box and FPRC-1100
(2) AC line cables
(1) Quick Start RS-232 Cable for test / debug
The Mounting Frame Assembly is typically shipped unassembled. Assembly directions
are detailed in the 1:1 FPC High Power Outdoor Mounting Kit Manual (#203187). Once
assembled, verify that the hardware is securely tightened for each High Power Outdoor
amplifier and make sure to observe the amplifier’s position indicator. If facing the
amplifier access doors, HPA 1 should be on the left hand side and HPA 2 should be on
the right hand side.
Verify that the connections of the Waveguide Switch Assembly mate with the proper
SSPA.
5.1.1 Signal Box Assembly
The Signal Box Assembly contains the RF input isolator and splitter that routes the RF
to each amplifier. It also routes the monitor and control signals from each amplifier
back to the FPRC-1100 system controller.
The signal box also contains a phase shifter. This phase shifter is in cascade with the
RF input to HPA 1. This allows the system to achieve optimum power combining and
is factory set for optimum combining across the full bandwidth of the amplifier. It should
not normally require adjustment in the field unless and amplifier has been replaced.
High Power Outdoor SSPA Operations Manual
202660 REV AB
99
5.2 1:1 Fixed Phase Combined System Operation with the FPRC-1100
Under normal system operation, both HPA 1 and HPA 2 are on-line. Their output power is combined at the magic-tee waveguide combiner. The waveguide combiner has
an integral RF sampler that provides a sample of the RF output sample at -40 dBc.
This port feeds an RF attenuator/diode detector combination. The detector’s output
voltage is sent back to the Signal box via a coaxial cable and linked to the FPRC-1100
Redundant Controller.
The FPRC-1100 is a 1RU indoor controller that can remotely monitor and control the
1:1 Fixed Phase Combined system. The controller has a very user friendly interface
that allows the operator to monitor the composite output power of the system and
adjust the gain of the amplifiers in 0.1 dB steps over a 20 dB range. The controller
adjusts each amplifier in the system and keeps the amplitude of each balanced for
optimal power combining.
The FPRC-1100 can be used in automatic or manual mode. In manual mode if a fault
occurs in one of the amplifiers, a fault will be indicated on the front panel but no waveguide switch change will occur. In automatic mode the controller will determine the appropriate waveguide switch positions and switch the remaining two amplifiers on line.
This will ensure that the system is operating at full output power capability.
Figure 5-3: FPRC-1100 Phase Combined System Controller
The FPRC-1100 front panel is shown in Figure 5-3. In most cases the user will place
the controller in Auto mode so that the controller can determine the proper switch position in the event of an amplifier failure. The mimic display shows the position of each
waveguide switch by lighting an LED in the waveguide switch path.
Detailed information on the installation and operation of the FPRC-1100 can be found
in the unit’s operations manual, Paradise Datacom drawing #205933.

High Power Outdoor SSPA Operations Manual
5.3 1:1 Fixed Phase Combined System with L-Band Input
The basic 1:1 Fixed Phase Combined system topology, shown in Figure 5-4, is very
similar to a 1:1 redundant system. When in Automatic mode, the waveguide switches
(S1& S2) either direct each amplifier output to the waveguide phase combiner or, if
lower output power is required, bypass the combiner and send a single amplifier output
to the system output. The system shown in Figure 5-4 utilizes a chain redundancy in
which the faults for BUC1 and HPA1 are linked, as are BUC2 and HPA2 faults.
Out
Figure 5-4: 1:1 Phase Combined System with HPA control of BUC redundancy
If a fault were to occur with either component in the chain, both components would be
treated as faulted, and would cause a switchover to the operational chain. If the system is operating in phase combined mode and a BUC or amplifier enters a fault condition, the system will switch to the operational thread. This provides a soft fail mode and
results in a power decrease of 3 dB to the system output power.
The BUC switch (SW3) is part of the converter assembly and is not controlled by the
FPRC. This switch is driven by the amplifiers when a fault is detected and will be
directed to place the operational BUC online without user intervention.
The system utilizes a chain redundancy architecture for fault handling. If a fault occurs
in a BUC or SSPA, the system will switch to the operational chain. This offers
redundancy in the L-Band portion as well as the SSPA portion of the system.
This system may also be operated via manual mode. This mode of operation may offer
some benefits over automatic operation. When in manual mode, the amplifiers will not
switch out of Phase Combined Mode or switch to the operational amplifier without user
intervention if an HPA fault occurs.
However, if a BUC fault occurs, the HPAs will direct Switch 3 to place the operational
BUC online. The fault indication will still be present on the front panel of the FPRC, but
the system output would be unaffected by the fault, thus indicating to the user that the
failure is with the BUC and not the HPA.

5.3.2 Signal Box Assembly
The Signal Box Assembly contains the Redundant BUC Assembly including the coaxial switch, the RF input isolator and splitter that routes the RF to each amplifier. It also
routes the monitor and control signals from each amplifier back to the FPRC-1100.
The signal box also contains a phase shifter. This phase shifter is in cascade with the
RF input to HPA 1. This allows the system to achieve optimum power combining and
is factory set for optimum combining across the full bandwidth of the amplifier. It should
not normally require adjustment in the field unless and amplifier has been replaced.
5.3.3 Redundant BUC Operation
The 1:1 Fixed Phase Combined System with L-Band Input is built utilizing a chain
redundancy architecture. This means if a Block Up Converter which is connected in
series with an SSPA fails, the SSPA will also fault. This will disable the system’s ability
to phase combine until the fault with the BUC is corrected.
Note: With the addition of a RCP2-1100 controller, the BUCs can function as an independent, fully redundant 1:1 system that is unaffected by the 1:1 phase combined
SSPA’s status.
5.3.4 Identifying a BUC Fault vs. SSPA Fault
In the event an SSPA or BUC would cause a fault, the FPRC-1100 will show this as a
summary alarm on the front panel. The BUC fault is recognized by the SSPA via the
Auxiliary Alarm input to the SSPA. The SSPA will recognize this fault as a Major Fault,
and will switch the BUC offline, along with itself.
102
202660 REV AB
High Power Outdoor SSPA Operations Manual
In order to identify which device is faulted, access the system information screen on
the FPRC-1100. Scroll down until the screen displays the EXT FAULT: AUX FAULT
section. If BUC 1 is faulted, the Auxiliary Fault will display AUX11101. If BUC 2 is faulted, the Auxiliary Fault will display AUX11110. If the Auxiliary Fault displays AUX11100
then no BUC fault is present and the fault is with the SSPA. The faulted SSPA is identified by the red LED on the front panel of the FPRC-1100.
5.3.5 Adjusting the 1:1 Phase Combining
The system is phase adjusted for optimum performance across the frequency band at
the factory, and no adjustments are typically needed except in the event that a SSPA
has been replaced.
The SSPAs are manufactured to a delay specification, but an adjustment may be
necessary to achieve the best operation in the system. After the new SSPA has been
placed in the system, apply power to the system and enable both amplifiers. Apply a
CW signal source to the input of the system and monitor the output power on the
FPRC-1100 LCD screen.
Measure the power out of the system with a single CW carrier (mid-band) applied to
the input. Remove the cover from the Signal Box and loosen the locking nut on the
phase adjuster (7/16”) and slowly rotate the knob clockwise. Continue to rotate the
knob until the output power is peaked.
For optimum performance across the entire frequency range of the SSPA system,
choose another frequency near each band edge and repeat the steps above. It may be
necessary to find the best compromise in output power for broadband use.
The BUCs are outside the phase combined loop. Therefore, replacing a BUC will not
impact the phase combining of the system, and no adjustment of the phase shifter is
necessary.
Securely fasten the cover back on to the Signal Box.

5.4 1:2 Fixed Phase Combined Systems
The 1:2 Fixed Phase Combined Redundant System is a popular system architecture
that enables Solid State Power Amplifiers to achieve higher output power levels while
building in full-power redundancy. The basic system topology is similar to a 1:2 redundant system and is shown in Figure 5-5.
Figure 5-5: Block Diagram, 1:2 Fixed Phase Combined System
In this system, HPA 1 and HPA 3 are normally online. The outputs of HPA 1 and HPA
3 are directed by the waveguide switches into a fixed phase combiner such as a waveguide “magic tee” style combiner. In the event of a failure of either on line amplifier, the
standby amplifier, HPA 2, can be switched in place of either HPA 1 or HPA 3 and the
system maintains full output power.
The 1:2 Fixed Phase Combined Amplifier System can be configured with any of the
High Power Outdoor Amplifiers listed in Appendix F. The output power of the system is
two-times the output power of the single SSPA.
System designers find that the 1:2 Fixed Phase Combined Amplifier System topology
is a very cost effective solution to realizing higher power amplifier systems. For example, it is less expensive to configure a 1 kW C-Band redundant system using (3) 500W
High Power Outdoor Amplifiers in a 1:2 Fixed Phase Combined redundant system than
it is to use (2) 1 kW amplifiers in a traditional 1:1 Redundant System.

(1) Quick Start RS-232 Cable for test / debug
The Mounting Frame Assembly is typically shipped unassembled. Assembly directions
are detailed in the 1:2 FPC High Power Outdoor Mounting Kit Manual (#208250). Once
assembled, verify that the hardware is securely tightened for each High Power Outdoor
amplifier and make sure to observe the amplifier’s position indicator. If facing the
access doors of the amplifiers, HPA 1 should be on the left hand side, HPA 2 should
be in the center, and HPA 3 should be on the right hand side as shown in Figure 5-6.
Verify that the connections of the Waveguide Switch Assembly mate with the proper
SSPA.
The FPRC-1200 controller is a 1 RU external controller specifically designed to handle
such an amplifier system. It not only handles all traditional fault monitoring and switching duties, but also provides an overall system monitor and control facility.
5.4.2 Signal Box Assembly
The Signal Box Assembly contains the RF input isolator, a three way splitter that
routes the RF signal to each amplifier, and two optional Block Up Converters. Monitor
and control signals from each amplifier pass through the signal box back to the FPRC1200 system controller.
The Signal Box also contains two phase shifters. These phase shifters are in cascade
with the RF input to HPA 1 and HPA 3. These allow the system to achieve optimum
power combining and are factory set for optimum combining across the full bandwidth
of the amplifier. They should not normally require adjustment in the field unless and
amplifier has been replaced. See Section 5.5.1 for directions on phase adjustment.

5.5 1:2 Fixed Phase Combined System Operation with FPRC-1200
Under normal system operation, HPA 1 and HPA 3 are on-line. Their output power
is combined at the magic-tee waveguide combiner. The waveguide combiner has an
integral RF sampler that provides a sample of the RF output sample at -40 dBc. This
port feeds an RF attenuator / diode detector combination. The detector’s output
voltage is sent back to the Signal box via a coaxial cable and fed to the FPRC-1200
Redundant Controller.
The 1:2 Fixed Phase Combined System is controlled by an FPRC-1200 1:2 external
Redundancy Controller. Detailed information on the installation and operation of the
FPRC-1200 can be found in the unit’s operations manual, Paradise Datacom drawing
#205933.
The FPRC-1200 can be used in automatic or manual mode. In manual mode if a fault
occurs in one of the amplifiers, a fault will be indicated on the front panel but no waveguide switch change will occur. In automatic mode the controller will determine the appropriate waveguide switch positions and switch the remaining two amplifiers on line.
This will ensure that the system is operating at full output power capability.
The FPRC-1200 front panel is shown in Figure 5-7. In most cases the user will place
the controller in Auto mode so that the controller can determine the proper switch position in the event of an amplifier failure. The mimic display shows the position of each
waveguide switch by lighting an LED in the waveguide switch path.
Figure 5-7: FPRC-1200 1:2 Phase Combined Redundant Controller
In normal operation, HPA 2 should be selected as the standby amplifier. HPA 2 is the
middle amplifier on the amplifier frame. This allows HPA 1 and HPA 3 to be combined
by the waveguide combiner. If HPA 1 or HPA 3 were to ever fail, HPA 2 can be
switched in place of either HPA 1 or HPA 3 and the system will still maintain full output
power capability over the full operating bandwidth of the amplifier. Figure 5-8 shows
the FPRC-1200 with HPA 2 selected as the standby amplifier.

5.5.1 Adjusting the 1:2 Phase Combining
Each 1:2 Fixed Phase Combined SSPA System has been factory set for optimal Phase
Combining before shipment and should not need adjustment during installation and
operation. In the event that an amplifier is replaced, it may then be necessary to make
additional phase adjustment.
The two phase adjusters are located inside the Signal Box and are labeled PA1 and
PA2. To make adjustments, open the cover to the Signal Box and loosen the 7/16”
locking nut at the bottom of each phase adjuster. Connect a power meter or spectrum
analyzer (if available) to the crossguide coupler at the output of the system after
removing the detector and attenuator. If a power meter or spectrum analyzer is not
available, you can access the detected voltage test points inside the signal box with a
voltmeter. See Figure 5-9.
Phase Adjusters PA2, PA1
Voltage Test Points
Figure 5-9: Signal Box showing voltage test points and phase adjusters
When possible, use a CW unmodulated signal to set the phase combining of the
system. This will allow you to reference the calibrated voltage vs. power chart on the
inside of the signal box cover to verify proper phase combining. See Figure 5-10. If a
CW unmodulated carrier is not available, adjust the phase combining until a peak
voltage is achieved (as voltage increases, power increases as well).
Figure 5-10: Measured voltages of combined HPAs listed inside signal box cover

High Power Outdoor SSPA Operations Manual
1. To adjust the phase combining, unmute all amplifiers and, using the FPRC1200, set HPA 1 as the standby amplifier so that HPA 2 and HPA 3 are
phase combined. See Figure 5-11. With a CW signal applied to the input of
the system, vary phase adjuster PA2 to maximize the power reading on the
power meter or spectrum analyzer or the FPRC-1200 controller’s output
power display. If using a voltmeter, maximize the measured voltage.
Figure 5-11:
With HPA 1 set as
standby, use PA2
to adjust phase
combining of
HPA 2 and HPA 3
2. Next, select HPA 3 as the standby amplifier. This combines the output power
of HPA 1 and HPA 2. See Figure 5-12. Use phase adjuster PA1 to optimize
power for this combination as done in Step 1.
Figure 5-12:
With HPA 3 set as
standby, use PA1
to adjust phase
combining of
HPA 1 and HPA 2
3. Select HPA 2 as the standby. This places the combined output power of
HPA 1 and HPA 3 online. See Figure 5-13. Either PA1 or PA2 can be used
to adjust the output power; the phase adjuster associated with the amplifier
pair with the greatest power should be used as a starting point. For example,
if the combined power of HPA 1 and HPA 2 is greater than that of HPA 2 and
HPA 3, use PA1. Otherwise use PA2.

With HPA 2 set as
standby, use
either PA1 or PA2

combining of

It may be necessary to repeat the steps above to verify the power with all HPA
combinations. Choose the best compromise in power for all combinations so that if a
switch over on fault does occur there is no noticeable increase or decrease in output
power.
After phase combining is complete use the locking nut on each phase adjuster to
secure the adjustment knob so no accidental changes to the combining occur.
Before placing the system back in operation, replace the cover to the Signal Box.

Section 6: L Band Operation
6.0 Block Up Converter Overview
The Teledyne Paradise Datacom SSPA is available with various L-Band up converter
options. The primary up converter option is the Zero dBm Block Up Converter, ZBUC.
The ZBUC® converter is offered in C-Band, X-Band, and Ku-Band configurations. See
Table 6-1 for specifications for the respective models. The ZBUC converter offers ultra
low phase noise for applications where phase noise is an overriding factor.
The type of BUC housed within your High Power Outdoor SSPA is indicated by its
model number, as shown in Figure 6-1. The example in Figure 6-1 shows a 250W KuBand High Power Outdoor SSPA with Internal Reference ZBUC. For a full description
of this model number structure, refer to the specification sheet (202589).

The block up converters are high performance frequency translation devices which
provide excellent phase noise and spurious performance. The ZBUC converter also
supports FSK communications for remote M&C capability. The FSK is a 650 KHz
signal that is multiplexed onto the L-Band input of the unit.
The ZBUC converter utilizes Teledyne Paradise Datacom’s proprietary “Smart
Reference Technology”. Smart Reference Technology allows the system user to
change reference frequency and power level or choose internal or external reference
without requiring any system configuration. An internal BUC adds about 1.7 pounds to
the overall weight of the SSPA.
It is important to remember the requirement of a 10 MHz reference oscillator when
operating an SSPA with BUC (SSPB). If the 10 MHz reference is not present, the M&C
will report a BUC alarm and the SSPA module will mute. This ensures that no spurious
or ‘off frequency’ transmission could originate from the amplifier.

6.2 ZBUC Theory of Operation
The ZBUC converter is a low gain block up converter with a P1dB of 0dBm. This topology allows the system to be integrated with little impact on the general electrical specifications of the SSPA module.
The ZBUC converter utilizes single up conversion from L-Band to the desired RF band.
The local oscillator circuits are designed to maintain the lowest possible output phase
noise. The frequency synthesizer utilizes industry leading technology which allows for
phase noise performance previously unattainable in PLL design. Typical phase noise
specifications are outlined in Table 6-2.

Band selectivity is accomplished using the most aggressive filtering possible while
maintaining specified power and spurious performance.
6.3 Smart Reference Technology
Teledyne Paradise Datacom’s ZBUC converter comes standard with smart reference
technology. Smart reference technology allows the system operator to change external
system reference frequency without any system configuration required. The ZBUC
converter will automatically sense and lock to a 10 MHz or 50 MHz system reference
frequency. With the internal reference option installed the ZBUC converter will operate
with no external reference applied. In the event the system operator wishes to operate
on external reference, the ZBUC converter will automatically sense the presence of an
external reference and switch to external reference mode. With the internal reference
option installed, the internal reference also becomes a backup reference which will become active in the event that external system reference is lost.
External reference is applied to the ZBUC converter via the L-Band input IFL and is
routed to the frequency synthesizer using the built-in demux circuitry.
High Power Outdoor SSPA Operations Manual
202660 REV AB
113
Notes:
The external reference option requires the system operator to provide
system reference to the ZBUC/SSPB. The system will not lock and will
have no output without external reference applied.
Internal reference option allows for either internal or external reference
operation.

6.4 ZBUC FSK Monitor and Control
With the ZBUC, FSK Monitor and control comes standard. This allows the High Power
Outdoor SSPB to be fully and remotely monitored and controlled through the system’s
IFL. An embedded controller enables remote communication and fault detection via the
IF input between the SSPA and a Paradise Datacom Evolution Series L-Band modem.
This signal consists of a 650 KHz Frequency Shift Keyed carrier that is multiplexed onto the L-Band input IFL along with the 10 MHz reference signal.
The ZBUC is capable of auto-sensing both the High Power Outdoor Serial Protocol, as
outlined in Section 7, and the VSAT BUC Protocol, detailed in drawing number
201410.
The FSK input has a center frequency of 650 KHz with a ± 5% tolerance. The FSK
deviation is ±60 KHz, with +60 KHz being a “mark” and -60 KHz being a “space”. The
FSK input will work over an input power range of -5 to -15 dBm. The FSK characteristics are summarized below:

6.6 IFL Cable Considerations
Consideration should be given to using a high quality IFL between the indoor
equipment and High Power Outdoor SSPB. The system designer must always
consider the total cable loss for a given length and also the implications of the slope of
attenuation across the 950 to 1450 MHz bandwidth. Table 6-3 gives the approximate
attenuation vs. frequency for a variety of cable types.

It is recommended to use a quality grade of 50 ohm cable such as Belden 9913, 9914,
or 7733. Check the manufacturer’s technical data to make sure that the insulation is
sufficient for the particular installation including the cable’s temperature range. Also
make sure the coaxial connector from the IFL cable to the High Power Outdoor input is
wrapped with a weather sealing tape to prevent water intrusion into the coaxial cable.

Section 7: Remote Control Interface
7.0 Overview
A system which includes an SSPA can be managed from a remote computer over a
variety of remote control interfaces (see Figure 7-1).
Figure 7-1: SSPA Remote Control Interface Stack
The parallel port on SSPA unit provides a simple form of remote control. There are 10
“dry” Form-C relay contacts for remote monitoring and six (6) galvanic isolated inputs
for remote control commands. Parallel interface is always enabled, and does not require any special settings to operate.
Serial interface supports both RS232 and RS485 standards. The control protocol supports two formats: Normal serial protocol (as detailed in Section 7.2) and ASCII based
protocol suitable for HyperTerminal applications (see Section 7.5). Serial interface is
equipped with overvoltage and overcurrent protection and benefits from full galvanic
isolation from the chassis ground for extra protection.
The Ethernet interface supports multiple communication standards which can be used
exclusively or simultaneously depending on the selected setting:
•
•
•
IPNet - UDP encapsulated Normal serial protocol (Section 7.6.10);
SNMP V1 with support of SNMP traps (Section 7.6.2);
HTTP web interface (Section 7.6.1.3);
High Power Outdoor SSPA Operations Manual
202660 REV AB
117
Serial protocol format for both RS232 and RS485 interfaces is set at no parity, 8 bit, 1
stop bit, no handshaking.
If using a Terminal mode protocol, the SSPA provides remote menu access through a
HyperTerminal program or through an actual hardware terminal.
The Ethernet interface is fixed to the 10Base-T standard. Normally, straight-through
CAT5 cable is used to connect the SSPA to a network hub, and crossover CAT5 is
used to connect directly to a computer’s Ethernet port.
J4 connector for RS232 utilizes standard DCE 9 pin pin-out (straight through cable requires for connecting to remote PC RS232 port). For this interface maximum cable run
of 100 feet can be achieved for 9600 Baud and lower speed rates with quality ground
shield cable.
RS485 interface pin out is compatible with most 9 pin RS485 adapters. Interface always works in half-duplex mode and suitable for either 4 or 2 wire RS485 configuration. Maximum achievable node length for this interface is 1500 feet. Proper termination and use of shielded twisted pair cable is required to achieve long cable runs.
Ethernet interface is auto selectable between 10 and 100 Mbit/s speeds. Maximum
node length is 100 feet. Use of CAT5E or CAT6 cables are preferred. CAT5 cable can
be used for 10Base-T standard or short runs of 100Base-T.
Digicor5 digital platform controller allows simulations support of multiple remote control
interfaces.

7.1 Remote Control - Parallel
7.1.1 Control Outputs
The hardware behind the form C relay is a single pole, double throw relay. Under
normal operation (no alarms) the relays are in an energized state. When a fault occurs
or the controller is powered off, the relays are in a de-energized state. The relay contacts are capable of handling a maximum of 30 VDC @ 1A . The form C relay is shown
schematically in Figure 7-2. The form C relay contact outputs are listed in Table 2-2.

7.1.2 Control Inputs
All parallel control inputs feature galvanic isolation from the chassis ground. Pull up resistors are provided on each input. To trigger a remote input command, the input
should be pulled to port signal ground. All inputs except the Auxiliary fault input are
pulse activated. Pulse relevant pin to signal ground (J7 pin 19) for at least 20mS for
function activation.
For example: To change the current mute state of the SSPA to opposite, provide momentary connection for at least 20 mS between pin 17 (Mute Input) of 37-pin connector
J7 to pin 19 (Signal Ground). Subsequent pulses will be ignored until Mute state is
changed to opposite. Typical time for command propagation depends on type of SSPA
and can vary from 100 to 500 mS. Current Mute state can be monitored by dry Form-C
relay contacts 4-23-5.
Auxiliary input is level activated. Auxiliary input function and logic is user selectable
through the front panel or over remote interface.
Mute input is set up to be pulse activated by default. However, by special request it
could be changed to level activated (Mute on Low or High logic levels). Contact Teledyne Paradise Datacom if you need Mute activation logic different than the default.

7.2.1.1 Frame Sync Word
The Frame Sync word is a two byte field that marks the beginning of a packet. This value is always 0xAA55. This field provides a means of designating a specific amplifier
packet from others that may exist on the same network. It also provides a mechanism
for a node to synchronize to a known point of transmission.
7.2.1.2 Destination Address
The destination address field specifies the node for which the packet is intended. It
may be an individual or broadcast address. The broadcast address is 0xFF. This is
used when a packet of information is intended for several nodes on the network. The
broadcast address can be used in a single device connection when the host needs to
determine the address of the amplifier. The amplifier will reply with its unique address.
7.2.1.3 Source Address
The source address specifies the address of the node that is sending the packet. All
unique addresses, except the broadcast address, are equal and can be assigned to
individual units. The host computer must also have a unique network address.

Settings can be modified at any time. Some of the settings may require hardware reset of the remote SSPA.
This tag allows access to the critical unit thresholds. Host
access status: Full Read/Write access. New thresholds
are in effect immediately after change.
This tag allows access to the unit’s internal conditions
flags, such as fault status or current system status. Host
access status: Read only. This type of the data can not
be set or modified remotely.
This tag allows access to the unit’s internal Analog to Digital converter. Host access status: Read only. This type of
the data cannot be set or modified remotely.
This tag is reserved.
7.2.2.5 Error Status / Data Address
This byte is a tag extension byte and specifies the first data element of the tagged data. If the Data Length is more than 1 byte, then all subsequent data fields must be accessed starting from the specified address. For example, if the requester wants to access the amplifier’s unique network address, it should set data tag 0 (Systems settings
tag) and data address 8 (see Systems Settings Details table). If the following Data
Length field is more than one (1), then all subsequent Settings will be accessed after
the Unique Network Address. When the Response Frame Data Address is omitted, this
byte position is replaced with the Error Status fields. The various error codes are given
in Table 7-4. Note that the Request and Response frames are different.

7.2.2.6 Data Length
This byte contains different information for Request and Response frames. In a
Request frame, it specifies the number of data bytes that are to be accessed starting
from the first byte of the value specified in the Data Address byte. That byte must not
exceed the maximum data bytes from a particular tag. The maximum data length for
the Settings tag is 26 bytes. The maximum data length for the System Threshold tag is
six (6) bytes.
7.2.2.7 Data Field
The actual data contained in the packet must be placed in this field. The “Get Request”
type of command must not contain any Data Field. Any “Get Request” will be rejected if
any data is present in the Data Field. Generally, the Bad Checksum error code will be
added to the response from the amplifier if the word size of the information is 16-bits or
2-bytes. Each data word is placed in the frame with its least significant byte first. All data with length of 2 bytes must be represented as integer type with maximum value
range from 32767 to (-32767).
7.2.3 Trailer Packet
The trailer component contains only one (1) byte called the Frame Check Sequence,
shown in Figure 7-6.

7.2.3.1 Frame Check
This field provides a checksum during packet transmission. This value is computed as
a function of the content of the destination address, source address and all Command
Data Substructure bytes. In general, the sender formats a message frame, calculates
the check sequence, appends it to the frame, then transmits the packet. Upon receipt,
the destination node recalculates the check sequence and compares it to the check
sequence embedded in the frame. If the check sequences are the same, the data was
transmitted without error.
Otherwise an error has occurred and some form of recovery should take place. In this
case, the amplifier will return a packet with the “Bad Checksum” error code set. CheckHigh Power Outdoor SSPA Operations Manual
202660 REV AB
123
sums are generated by summing the value of each byte in the packet while ignoring
any carry bits. A simple algorithm is given as:
Chksum=0
FOR byte_index=0 TO byte_index=packet_len-1
Chksum=(chksum+BYTE[byte_index]) MOD 256
NEXT byte_index
7.3 Timing issues
There is no maximum specification on the inter-character spacing in messages. Bytes
in messages to amplifier units may be spaced as far apart as you wish. The amplifier
will respond as soon as it has collected enough bytes to determine the message. Generally, there will be no spacing between characters in replies generated by unites. The
maximum length of the packet sent to the amplifier node should not exceed 64 bytes,
including checksum and frame sync bytes. Inter-message spacing must be provided
for good data transmission. The minimum spacing should be 100 ms. This time is required for the controller to detect a “Line Cleared” condition with half duplex communications. Maximum controller respond time is 200 ms.

7.6 Terminal Mode Serial Protocol for Paradise Datacom SSPA
The Teledyne Paradise Datacom High Power Outdoor SSPA utilizes Terminal Mode
Serial Protocol (TMSP) as a secondary serial protocol for Management and Control
through a Remote Serial Interface.
TMSP allows the user to access internal SSPA functions via a remote ASCII Terminal
or its equivalent (such as HyperTerminal for Windows). TMSP is accomplished through
either the RS-232 or RS-485, half duplex, serial communication link. US ASCII encoded character strings are used to represent commands and data massages.
A remote terminal or controller initiates a communication session and the SSPA Terminal takes action and returns a report of requested status. The SSPA terminal will not
initiate communication and will transmit data only when commanded to do so. Prior to
establishing the session with the SSPA Terminal, this mode must be enabled through
the SSPA front panel menu.
The remote terminal must be configured with serial settings that match the SSPA’s serial port settings. For example, if the SSPA is set at 9600 Baud, the remote terminal
must be also configured as ASCII terminal at 9600 Baud, no parity, 8 bit data with 1
stop bit serial connection. The SSPA will not echo back any incoming characters, so
local echo must be enabled on the remote terminal.
To establish a remote control session with the SSPA terminal, the user must type:
UNIT#XXX
in the terminal window (all letters must be in upper case), where XXX is the RM SSPA
unique network address or the global call address (255). Press the "Enter" key on Remote Terminal keyboard.
The SSPA should answer with words "Unit#XXX OnLine" with the first menu screen on
the following lines. After a remote session is successfully established, the unit will stay
connected as long as needed. The session interface mimics the SSPA's front panel
menu. To help the user navigate through the menu, the help string with the list of active keys always follows the menu strings. For example:
"Active Keys:(U)p+Enter;(D)own+Enter;(C)lrearFlt; (M)enu+Enter; (E)nd+Enter"
will be the last transmission string on all informative menu screens.
Note: all letters must be in upper case!
To refresh current screen on the Remote Terminal simply press "Enter" key. To end a
session with RM SSPA, press "E" and then "Enter" keys.

Important! If multiple SSPA units are networked on the same serial link. DO NOT
ESTABLISH A SESSION WITH MORE THAN ONE SSPA AT THE SAME TIME. If
you do so you will not get any valid answer from the SSPA!

7.7 Ethernet Interface
The rack mount SSPA Ethernet Port (J9) supports several IP network protocols to
provide a full featured remote M&C interface over an Ethernet LAN.
•
•
IPNet protocol – redirection of standard Paradise Datacom LLC serial
protocol over UDP transport layer protocol. This protocol is fully supported in Paradise Datacom LLC’s Universal M&C software.
SNMPv1 protocol - protocol intended for integration into large corporate
NMS architectures.
In order to utilize either of the protocols listed above, the relevant interface option has
to be turned on. Refer to Section 7.7.1.2 and Section 7.7.2.4 for details.
Of course, standard IP level functions such as ICMP Ping and ARP are supported as
well. There is currently no support for dynamic IP settings, all IP parameters.
7.7.1 IPNet Interface
7.7.1.1 General Concept
Satcom system integrators are recognizing the benefits of an Ethernet IP interface.
These benefits include:
•
•
•
•
Unsurpassed system integration capabilities;
Widely available and inexpensive set of support equipment (network cable; network hubs);
Ability to control equipment over Internet;
Ease of use
Implementation of the raw Ethernet interface is not practical due to the limitations it
places on M&C capabilities by the range of a particular LAN. It is more practical to use
an Ethernet interface in conjunction with the standard OSI (Open System Interconnect)
model to carry a stack of other protocols. In an OSI layered stack, an Ethernet interface can be represented as a Data Link layer. All upper layers are resolved through a
set of IP protocols. In order to keep data bandwidth as low as possible (which is important when M&C functions are provided through a low-bandwidth service channel)
the IP/UDP protocol set is used as the Network/Transport layer protocol on Paradise
Datacom SSPAs.
UDP (User Datagram Protocol) was chosen over TCP (Transmission Control Protocol)
because it is connectionless; that is, no end-to-end connection is made between the
SSPA unit and controlling workstation when datagrams (packets) are exchanged.
High Power Outdoor SSPA Operations Manual
202660 REV AB
135
Paradise Datacom provides a WindowsTM-based control application to establish UDPbased Ethernet communication with SSPAs. The control application manages the exchange of datagrams to ensure error-free communication. An attractive benefit of UDP
is that it requires low overhead resulting in minimal impact to network performance.
The control application sends a UDP request to SSPA unit and waits for response. The
length of time the control application waits depends on how it is configured. If the
timeout is reached and the control application has not heard back from the agent, it assumes the packet was lost and retransmits the request. The number of the retransmissions is user configurable.
The Paradise Datacom SSPA Ethernet IP interface can use UDP ports from 0 to 65553
for sending and receiving. The receiving port needs to be specified through the front
panel menu. For sending, it will use the port from which the UDP request originated. Of
course, it is up to the user to select an appropriate pair of ports that are not conflicting
with standard IP services. Paradise Datacom recommends usage of ports 1038 and
1039. These ports are still not assigned to any known application.
As an application layer protocol (which actually carries meaningful data), the standard
Paradise Datacom SSPA serial protocol was selected. This protocol proves to be extremely flexible and efficient. It is also media independent and can be easily wrapped
into another protocol data frame. An example of the UDP frame with encapsulated Paradise Datacom protocol frame is shown on Figure 7-8.

7.7.1.2 Setting IPNet Interface
Before enabling the Ethernet IP interface, the following IP parameters need to be set:
IP Port address, Default Gateway, Subnet Mask, Receive IP Port and Lock IP address.
All IP related menu items consolidate under the Communication Setup menu. Press
the Main Menu key, select 2.Com.Setup and press the Enter key, select 5.IP Setup
and press the Enter key.
The Lock IP address is a security measure. Setting this parameter either to
255.255.255.255 or 0.0.0.0 will allow any host to control the SSPA. Setting the parameter to the specific address of the remote host will lock SSPA access to this host.
Packets received from other hosts will be ignored.
For other parameters (IP address, Gateway, Subnet, IP port) contact your network system administrator for assistance.
Important! If the SSPA RM will be accessible over the Internet, exercise
appropriate security measures. Teledyne Paradise Datacom strongly recommends placing amplifiers behind a protective Firewall or setting up a
VPN link for remote access.
After selecting the IP parameters, turn on IP interfaces through front panel: Press the
Main Menu key, select 2.Com.Setup, press the Enter key; select 4.Interface, press
the Enter key; select 3.IPNet and press the Enter key.
Ethernet Interface is now the primary remote control interface and the RS232/485 Main
port is disabled. The user may adjust any IP settings when the IPNet interface is turned
on, as needed, without losing IP link. New settings become effective only after a hardware reset (press the Main Menu key; select 5.Options and press the Enter key; select 6.Reset and press the Enter key; select 3.Coms Only and press the Enter key; or
cycle power to the unit).
To disable the Ethernet port and enable the RS-232/RS-485 Serial Main port, press
the Main Menu key and select 2.Com.Setup, press the Enter key; select 4.Interface,
press the Enter key; select either 1.RS232 or 2.RS485, and press the Enter key.
Important! At present, the SSPA controller supports only one remote
control protocol selection through its Ethernet interface port. This protocol
is referred to as “Normal” on the front panel display (See Section 3.1
through Section 3.6). If the protocol selection is set differently (Terminal),
the controller will force its protocol selection to “Normal”.
The High Power SSPA Ethernet port can be connected to a network hub through
straight through network cable or directly to a work station NIC card through a nullmodem or cross-over cable (Rx and Tx lines are crossed). As soon as an Ethernet
High Power Outdoor SSPA Operations Manual
202660 REV AB
137
interface has been selected as the primary interface, you should be able to verify the
network connection to the unit by using the Ping command from your host workstation.
To do so on a Windows based PC, open a Command Prompt window and type PING
and the dot delimited IP address of the SSPA, then press the Enter key. If the unit is
successfully found on the network, the request statistic will be displayed.
If the unit does not answer on the ping command, check all hardware connections and
verify that the IP settings on your host workstation and the RM SSPA match your network parameters. On a Windows based PC you may also check ARP table entries.
The new IP address of the SSPA may be set to another PC or network equipment with
a different MAC address.
Open a Command Prompt window and type "ARP -a”, the press Enter. The current table will be displayed. If you see the SSPA IP address entry in the table, delete it by issuing the command "ARP -d XXX.XXX.XXX.XXX” and press Enter, where
XXX.XXX.XXX.XXX is the IP address of the SSPA unit. Try the PING command again.
More information about how to set up a network connection with the SSPA can be
found in Appendix B.
7.7.1.3 Using the Web Interface
Starting with firmware version 6.00, the rack mount web interface no longer needs to
have a pre-installed Java application to operate. The web interfaces uses a standard
hypertext transfer protocol on port 80. The web interface is compatible with most modern web browsers, such as Firefox, Chrome or Internet Explorer, which support asynchronous JavaScript XML transactions (aka AJAX).
To connect to SSPA internal web page, the user must make sure Web/IPNet interface
is enabled on the device (See Section 7.6.1.2) and that an IP address has been assigned to the unit. Connect the unit to an Ethernet network or directly to a PC 10/100
Base-T adapter and then open a web browser.
Enter IP address of the unit into the address bar of the browser. A security login window will appear. In the User Name field, enter admin, the default User Name. See
Figure 7-9. The User Name is fixed and cannot be changed by the operator.

7.7.2 SNMP interface
7.7.2.1 Introduction
SNMP-based management was initially targeted for TCP/IP routers and hosts. However, the SNMP-based management approach is inherently generic so that it can be
used to manage many types of systems. This approach has become increasingly popular for remote management and control solutions for various SSPA systems.
Teledyne Paradise Datacom devices with Ethernet interface support the most popular
SNMPv1 format (SMIv1, RFC1155), SNMP Get, SNMP GetNext and SNMP Set commands. SNMP Traps are currently unsupported.
In order to utilize SNMP protocol, the operator has to enable this feature through the
front panel or by remote serial protocol. SNMP uses the UDP fixed port 161.
The definition of managed objects described in the Management Information Base
(MIB) file. The MIB file is available for download from the Downloads section of the
Teledyne Paradise Datacom web site, http://www.paradisedata.com.
7.7.2.2 Interface
The Teledyne Paradise Datacom MIB is a table-based MIB, and is the same for all devices. The MIB table is designed to follow the same pattern as the tables for serial protocol. For additional information about OID values, refer to Tables 7-11 through 7-13.
The text values in the tables help automatic value parsing within NMS or make the values readable through an MIB browser. All text value OIDs follow the same pattern:
1. For settings or parameters with discreet values:
SettingName’ValueName1=xxx, ….,ValueNamex=xxx
Example: ControlMode’Local=0,Remote=1
2. For settings or parameters with continuous values:
SettingName’LowLimit..HighLimit
Example: NetworkAddress'0..255
As with the serial protocol, the MIB allows access to a remote SSPA (default state) as
well as to the RCP unit itself. To switch between those devices’ MIBs, the proper Device Type has to be selected (OID -1.3.6.1.4.1.20712.1.4).
7.7.2.3 SNMP V3 issues in Teledyne Paradise Datacom SSPAs
Simple Network Management Protocol (SNMP) is an interoperable standards-based
protocol that allows for external monitoring of the Content Engine through an SNMP
agent.
140
202660 REV AB
High Power Outdoor SSPA Operations Manual
A SNMP-managed network consists of three primary components: managed devices,
agents, and management systems. A managed device is a network node that contains
a SNMP agent and resides on a managed network. Managed devices collect and store
management information and use SNMP to make this information available to management systems that use SNMP. Managed devices include routers, servers, switches,
bridges hubs, computer hosts, and printers.
An agent is a software module that has local knowledge of management information
and translates that information into a form compatible with SNMP: the Management
Information Base (MIB). The agent can send traps, or notification of certain events, to
the manager. Essentially, a Teledyne Paradise Datacom SSPA is considered a “SNMP
agent”.
A manager is a software module that listens to the SNMP notifications sent by SNMP
agents. The manager can also send requests to an agent to collect remote information
from the Management Information Base (MIB).
The communication between the agent and the manager uses the SNMP protocol,
which is an application of the ASN.1 BER (Abstract Syntax Notation 1 with Basic Encoding Rules), typically over UDP (for IP networks).
• Version 1 (SNMPv1, described in RFC 1157) is the initial implementation
of SNMP.
• Version 2 (SNMPv2c, described in RFC 1902) is the second release of
SNMP. It provides additions to data types, counter size, and protocol operations.
• Version 3 (SNMPv3, described in RFC 2271 through RFC 2275) is the
most recent version of SNMP.
SNMP V1
SNMP version 1 (SNMPv1) is the initial implementation of the SNMP protocol.
SNMPv1 operates over protocols such as User Datagram Protocol (UDP), Internet
Protocol (IP), OSI Connectionless Network Service (CLNS), AppleTalk DatagramDelivery Protocol (DDP), and Novell Internet Packet Exchange (IPX). SNMPv1 is widely used and is the de-facto network-management protocol in the Internet community.
The Teledyne Paradise Datacom SSPA family of products utilizes the most popular implementation, SNMP V1 over UDP transport layer.
SNMP V2
SNMPv2 (RFC 1441–RFC 1452) revises version 1 and includes some improvements
in the areas of performance, security, confidentiality, and manager-to-manager communications. It introduced GetBulkRequest, an alternative to iterative GetNextRequests for retrieving large amounts of management data in a single request.
High Power Outdoor SSPA Operations Manual
202660 REV AB
141
However, the new party-based security system in SNMPv2, viewed by many as overly
complex, was not widely accepted.
The format of the trap message was also changed in SNMPv2. To avoid these compatibility issues, the trap mechanism was not implemented in the Teledyne Paradise Datacom SSPA MIB.
SNMP V3
Although SNMPv3 makes no changes to the protocol aside from the addition of cryptographic security, it looks much different due to new textual conventions, concepts, and
terminology. SNMPv3 primarily added security and remote configuration enhancements to SNMP.
Many embedded controllers and microprocessors that are used in electronic components such as amplifier modules do not have support for SNMP V2 or V3. This is due
to the extensive memory resources required by the computation intensive cryptographic security of SNMP V3.
For this reason V3 has not gained widespread support amongst embedded MCU
platform manufacturers. Existing port implementations are limited to very powerful
ARM5 or above cores, running under full-scale OS systems (Linux, Android, etc.). At
large, these configurations require external bulk RAM/FLASH to operate. This requirement ultimately affects the minimum device startup time (tens of seconds, due to the
large boot BIOS) and working temperature range (mostly indoor).
As noted in Cisco’s release notes about SNMP V3:
SNMP notifications can be sent as traps or inform requests. Traps are unreliable because the receiver does not send acknowledgments when this device receives traps. The sender cannot determine if the traps were received.
However, an SNMP entity that receives an inform request acknowledges
the message with an SNMP response protocol data unit (PDU). If the sender never receives the response, the inform request can be sent again.
Therefore, informs are more likely to reach their intended destination.
However, informs consume more resources in the agent and in the network.
Unlike a trap, which is discarded as soon as it is sent, an inform request
must be held in memory until a response is received, or the request times
out. Traps are sent only once, while an inform can be retried several times.
The retries increase traffic and contribute to a higher overhead on the network.

Appendix B: Proper 10/100 Base-T
Ethernet Cable Wiring
This section briefly describes the basic theory related to the physical layer of 10/100
Base-T networking, as well as proper wiring techniques.
There are several classifications of cable used for twisted-pair networks. Recommended cable for all new installations is Category 5 (or CAT 5). CAT 5 cable has four twisted pairs of wire for a total of eight individually insulated wires. Each pair is color coded
with one wire having a solid color (blue, orange, green, or brown) twisted around a
second wire with a white background and a stripe of the same color. The solid colors
may have a white stripe in some cables. Cable colors are commonly
described using the background color followed by the color of the stripe; e.g., white-orange is a cable with a white background and an orange stripe.
The straight through and crossover patch cables are terminated with CAT 5 RJ-45
modular plugs. RJ-45 plugs are similar to those you'll see on the end of your
telephone cable except they have eight versus four or six contacts on the end of the plug
and they are about twice as big. Make sure they are rated for CAT 5 wiring. (RJ
means "Registered Jack"). A special Modular Plug Crimping Tool (such as that shown
in Figure B-1) is needed for proper wiring.
Figure B-1: Modular Plug Crimping Tool
The 10BASE-T and 100BASE-TX Ethernets consist of two transmission lines. Each
transmission line is a pair of twisted wires. One pair receives data signals and the other pair transmits data signals. A balanced line driver or transmitter is at one end of one
of these lines and a line receiver is at the other end. A simplified schematic for one of
these lines and its transmitter and receiver is shown in Figure B-2.
Figure B-2: Transmission Line
High Power Outdoor SSPA Operations Manual

The main concern is the transient magnetic fields which surrounds the wires and the
magnetic fields generated externally by the other transmission lines in the cable, other
network cables, electric motors, fluorescent lights, telephone and electric lines, lightning, etc. This is known as noise. Magnetic fields induce their own pulses in a transmission line, which may literally bury the Ethernet pulses.
The twisted-pair Ethernet employs two principle means for combating noise. The first is
the use of balanced transmitters and receivers. A signal pulse actually consists of two
simultaneous pulses relative to ground: a negative pulse on one line and a positive
pulse on the other. The receiver detects the total difference between these two pulses.
Since a pulse of noise (shown in red in the diagram) usually produces pulses of the
same polarity on both lines one pulse is essentially canceled by out the other at the
receiver. In addition, the magnetic field surrounding one wire from a signal pulse is a
mirror of the one on the other wire. At a very short distance from the two wires, the
magnetic fields are opposite and have a tendency to cancel the effect of each other.
This reduces the line's impact on the other pair of wires and the rest of the world.
The second and the primary means of reducing cross-talk between the pairs in the
cable, is the double helix configuration produced by twisting the wires together. This
configuration produces symmetrical (identical) noise signals in each wire. Ideally, their
difference, as detected at the receiver, is zero. In actuality, it is much reduced.
Pin-out diagrams of the two types of UTP Ethernet cables are shown in Figure B-3.
Figure B-3: Ethernet Cable Pin-Outs
Note that the TX (transmitter) pins are connected to corresponding RX (receiver) pins,
plus to plus and minus to minus. Use a crossover cable to connect units with identical
interfaces. If you use a straight-through cable, one of the two units must, in effect,
perform the crossover function.
Two wire color-code standards apply: EIA/TIA 568A and EIA/TIA 568B. The codes are
commonly depicted with RJ-45 jacks as shown in Figure B-4. If we apply the 568A color code and show all eight wires, our pin-out looks like Figure B-5.
Note that pins 4, 5, 7, and 8 and the blue and brown pairs are not used in either
standard. Quite contrary to what you may read elsewhere, these pins and wires are
not used or required to implement 100BASE-TX duplexing.

Again, the wires with colored backgrounds may have white stripes and may be
denoted that way in diagrams found elsewhere. For example, the green wire may be
labeled Green-White. The background color is always specified first.
Now, all you need to remember, to properly configure the cables, are the diagrams for
the two cable ends and the following rules:
•
•
A straight-thru cable has identical ends.
A crossover cable has different ends.
It makes no functional difference which standard you use for a straight-thru cable.
You can start a crossover cable with either standard as long as the other end is the
other standard. It makes no functional difference which end is which. 568A patch
cable will work in a network with 568B wiring and 568B patch cable will work in a 568A
network
Here are some essential cabling rules:
1. Try to avoid running cables parallel to power cables.
2. Do not bend cables to less than four times the diameter of the cable.
3. If you bundle a group of cables together with cable ties (zip ties), do not over
-cinch them. It's okay to snug them together firmly; but don't tighten them so
much that you deform the cables.
4. Keep cables away from devices which can introduce noise into them. Here's
a short list: copy machines, electric heaters, speakers, printers, TV sets, fluorescent lights, copiers, welding machines, microwave ovens, telephones,
fans, elevators, motors, electric ovens, dryers, washing machines, and shop
equipment.
5. Avoid stretching UTP cables (tension when pulling cables should not exceed
25 LBS).
6. Do not run UTP cable outside of a building. It presents a very dangerous
lightning hazard!
7. Do not use a stapler to secure UTP cables. Use telephone wire/RG-6 coaxial wire hangers, which are available at most hardware stores.

Control with Paradise Datacom Universal M&C
C.1 Adding a New High Power Outdoor SSPA to the Universal M&C
To add a new unit, choose “Action->Add Unit” from the Main Menu. Then choose
“Rackmount SSPA” (The High Power Outdoor SSPAs use the same configuration as
the Rackmount SSPAs in the Universal M&C software). When a unit type is chosen a
“New Rackmount SSPA” dialog will appear for the particular unit you are adding, as
shown in Figure C-1.
Figure C-1: New Rack Mount SSPA Dialog Window
To add a single SSPA to the M&C Utility, fill in the appropriate boxes in the “New Rackmount SSPA” dialog window.
Entering a Unit ID is not required, although it is recommended. If a Unit ID is not entered, the Universal M&C Utility will assign a Unit ID.
To add a unit connected to a serial port, supply a Communication Port and Baud Rate.
To add a unit connected via Internet Connection, supply an IP Address.
Specify the Unit’s Unique Address in the Amplifier Address box. If the address of the
unit is unknown, press the [Search for Unit] button. This search feature is only useful
when only one unit is connected to the PC.

Choose a log file location by clicking the Browse... button. The default is the "My Documents" folder. The log file name will be the UnitID and the extension ".log" appended
to it. i.e. "Unit1.log".
D.2 SSPA overview for the Universal M&C
Each SSPA in the M&C has five screens. The first screen is the “Status” tab, shown in
Figure C-2. The Status tab shows the current conditions (or state) of the connected
Rack Mount SSPA. In addition, the Status tab allows the operator to change the Mute
state of the carrier and allows adjustment of the on-board attenuator for gain control.
Figure C-2: SSPA Status Window
The second screen is the “Faults” tab, shown in Figure C-3. It shows the user the status of all faults on-board the SSPA. Each RF Module in the SSPA is monitored for
faults in addition to the SSPA itself. If the SSPA does not include a module, then it will
show up as N/A in the Module Status box.
Figure C-3: SSPA Faults Window

High Power Outdoor SSPA Operations Manual
The third screen is the “Settings” tab, shown in Figure C-4. It shows the user all available settings on the SSPA. All user-adjustable settings are allowed to be modified to suit
the specific needs of the customer. However, it should be noted that the SSPA is configured for the customer at the factory. If modification of any settings is necessary
please refer to the SSPA Manual.
Figure C-4: SSPA Settings Window
The fourth screen is the “IP Setup” screen, shown in Figure C-5. It shows the user all
of the TCP/IP settings on the SSPA.
When the IP Address is modified, the SSPA must be reset for it to use the new IP Address. Until the SSPA is reset, it will use the old IP Address. The Local Port is the port
that the SSPA listens to for UDP requests. The SSPA also answers requests using the
same port. If the Local Port is changed, the SSPA must be reset.
Figure C-5: IP Setup Window

The Gateway Address and Subnet Mask are standard settings for TCP/IP communications. If either of these settings is changed, the SSPA must be reset for the new settings to take effect.
The IP Lock Address is used for security. If it is set to something besides 0.0.0.0 or
255.255.255.255 it will only answer the address it is set to. For example, if the IP Lock
Address is 192.168.0.50, then a request from 192.168.0.100 will not be accepted. The
IP Lock Address may be changed without resetting the SSPA.
Figure C-6: N+1 Settings and Conditions Window
The fifth window is the N+1 Settings and Conditions tab, as shown in Figure C-6. This
screen is used for setting N + 1 system parameters, and monitoring N+1 system conditions. Note that only the master module in an N+1 system will show the N+1 Master
Settings.

Appendix D: Automatic Level Control
D.1 Activating Automatic Level Control
Automatic Level Control can be activated via the front panel by following the steps
listed below:
1.Select the [Main Menu] button;
2.Select [4] Fault setup;
3.Select [5] Low RF/ALC;
4.Select [3] ALC On;
5.Select [5] Level;
6.Use the arrow keys to set the desired output level.
Once activated, the ALC will take control of the amplifier’s attenuation setting to
maintain the desired RF output power level and will not allow any attenuation
adjustments via the front panel. The ALC circuit will have the greatest ability to adjust
for positive and negative RF input level changes when the amplifier’s gain level is
typically 65 dB. By following the steps below, the optimum ALC RF input level can be
set quickly.
1.Using the front panel menu, make sure the amplifier is not in ALC mode;
2.Set the amplifier attenuation level to 10 dB;
3.Apply a CW RF signal to the amplifier;
4.Use a power meter to measure the output power of the amplifier;
5.Adjust the RF input level until the desired output power level is achieved;
6.Follow the steps listed above to activate the ALC control. The ALC will take
over the control of the output level and maintain the RF output level set
point.
The ALC has the ability to accurately control the RF output power over a 15 dB range
from Psat. The ALC will operate over a 20 dB range, but the accuracy of the last 5 dB
will suffer. For example, if the saturated power from the amplifier is 59 dBm, the lowest
accurate power setting during ALC control is 44 dBm.
If the output power set point is set outside the operational range of the ALC circuit, the
ALC will adjust the output power to the lowest possible level and set a minor fault on
the amplifier’s front panel.
D.2 Timing Issues with ALC
The ALC circuit is designed to compensate slow and steady drift of input signal and
can’t compensate sudden signal level changes. Overall adjustment speed depends on
the type of required adjustment.
High Power Outdoor SSPA Operations Manual
202660 REV AB
165
For changes that require more than 5 dBm of level adjustments, ALC performs coarse
adjustment first (output signal will be adjusted within ±2 dBm range) and then perform
fine adjustment to get the output signal to within a ±0.3 dBm range from the set value.
For changes less than 5 dBm, the ALC circuit will not use coarse adjustment at all.
Overall time lag will be cumulative from the coarse and fine adjustment procedures.
Coarse adjustment speed is approximately 5 dBm/sec. Fine adjustment speed is
approximately 0.5 dBm/sec.

The following instructions describe the assembly of the uni-strut mounting kit, and the
installation of the High Power Outdoor SSPA. It is intended to be free standing and
entirely self-supported once properly mounted.
It is important to give consideration to the following:
1. 1. Structural integrity of the mounting deck.
2. 2. Accessibility to all local user interfaces. (Ensure the SSPA enclosure door
is free to open to the latched position.)
3. 3. Adequate cooling air; an 8.00” minimum clearance must be maintained
between air intake and any surface that will inhibit air flow.
4. 4. The High Power Outdoor SSPA should never be enclosed in such a manner that airflow is restricted. Normal operating range is -40 to +60°C.
5. 5. Proper weatherized sealing of all connectors.
Note: The High Power Outdoor SSPA should not be positioned in such a
way that allows falling precipitation to enter the fans at the bottom of the
amplifier. Doing so will void your warranty.

Figure E-2: Mounting hardware configurations
Reference the ‘B’ Configuration of Figure E-2 for the required hardware for
this step. At the intersections of the vertical and cross struts, install 3 spring
loaded, self-holding nuts (Item 6) into the channel of each vertical strut. Secure the vertical struts to the cross struts using a 1/2-13x2.75” hex head bolt
(Item 10), flat washer (Item 7), and square channel washer (Item 9) at each
position.
Check against the dimensions in Figure E-1 to ensure the spacing is correct
and tighten all hardware at the junctures labeled ‘B’ in Figure E-1.
2. Locate two (2) 5-hole angle brackets (Item 4). At the bottom of each vertical
strut install a pair of spring loaded self holding nuts (Item 6). Reference Figure E-1 and the ‘C’ Configuration of Figure E-2 for the required hardware.
Using 1/2-13x1.25” hex head bolts (Item 8) and flat washers (Item 7), attach
the short side of the 5-hole angle bracket to the vertical strut such that the
long side of the angle bracket is in line with the bottom edge of the vertical
strut. Repeat for the other two vertical struts. Tighten all bolts.
3. The framework consisting of the vertical strut sections (Item 2) and the cross
strut sections (Item 3) should be checked dimensionally against Figure E-1,
and for square-ness. Verify that all hardware is secured as stated in the
above steps before proceeding to Step 4.
4. Locate the two (2) base struts (Item 1) and arrange them channel side up,
spaced as shown in Figure E-1. Slide a pair of spring loaded, self-holding
nuts (Item 6) into the channels of each base strut. These will be used to secure the bolts through the long side of each 5-hole angle bracket from Step
2. Raise the frame to the upright position and set the vertical struts (Item 2)
directly on each base strut so that the back of each vertical strut is 7.5” from
the back edge of the base struts. Align the self-holding nuts in the base strut
channels with the holes in the long side of the 5-hole angle brackets. Secure
as shown in Figure E-2, ‘C’ Configuration.
High Power Outdoor SSPA Operations Manual
202660 REV AB

5. With the vertical strut framework mounted to the base struts, install one
spring loaded self holding nut (Item 6) in each vertical strut and one toward
the rear of each base strut. Position a corner brace (Item 5) as shown in Figure E-2 and align the corresponding self holding nuts to the hole locations of
the corner brace. Reference Figure E-2, ‘C’ Configuration for the required
hardware. Attach each corner brace with a 1/2-13x1.25” hex head bolt (Item
8) and flat washer (Item 7). Tighten all bolts.
6. Slide a self holding nut (Item 6) in each of the base strut (Item 1) channels
approximately 6 3/4” from the front of each base strut. Referencing the ‘B’
Configuration of Figure E-2, mount the remaining cross strut (Item 3) to the
base struts (Item 1) using two (2) 1/2-13x2.75” hex head bolts (Item 10),
and square channel washers (Item 9). Tighten all bolts.
7. Reference the ‘A’ Configuration of hardware in Figure E-2. Install spring
loaded self holding nuts (Item 6) at each of the positions labeled ‘A’ shown in
Figure E-1. Install the 1/2-13x1.25” hex head bolt (Item 8) and flat washer
(Item 7) into the self holding nuts on the bottom cross strut only. These will
be used to help support the HPA as you attach it to the frame.
8. With the mounting frame assembly fully erected, verify all framework is
square and cross strut (Item 3) locations correspond to the dimensions provided in Figure E-1.
9. Ensure all hardware is tightened as detailed in the above steps before
proceeding to Step 9.
Warning: Because the HPA unit is designed for operation in environmental extremes, all mechanical packaging is robust and substantial in size and weight. Each unit weights 145 lbs (66 kg). Caution is advised during the mounting of the HPA to the framework assembly.
Mechanical support/lift is suggested for mounting of the HPAs. If
mounting is to be done without the benefit of mechanical assistance, no fewer than three (3) individuals should attempt installation. Two individuals capable of
supporting the HPA must participate in positioning the HPA on the framework assembly while a
third individual must be capable of installing the associated mounting hardware. Review all steps before proceeding.
At this time, anchor the mounting frame either to the prepared concrete decking, or to any suitable alternative installation. Make sure
the frame is secure before attempting to attach the HPA to the
frame. Failure to do so may result in injury or damage to the equipment.

Figure E-3: Mounting the HPA to the Frame
10. Reference Figure E-3. Position the HPA so that the slotted mounting slots in
the HPA chassis align with the mounting bolts on the bottom cross strut
(labeled 1st in Figure E-3). Slide the HPA onto these mounting bolts, making
sure the washer and bolt head can secure the HPA chassis to the frame. Do
not allow the full weight of the HPA to rest on just these two mounting
bolts.
11. Position the mounting holes of the HPA to align with the self holding nuts
(Item 6) on the top and middle cross struts (labeled 2nd and 3rd in Figure E3). Attach with the four (4) remaining sets of 1/2-13x1.25” hex head bolts
(Item 8) and flat washers (Item 7). Tighten bolts to snug, but allow some
freedom to slide the HPA if necessary, to allow adjustment for the attachment of the waveguide.
12. Connect the waveguide to the RF Output flange. Securely tighten the
mounting hardware designated ‘A’ in Figure E-1. Connect all cables, making
sure all connectors are oriented correctly and that the pins align. Do not attempt to force the connector into its receptacle.
13. As a precaution, all connections should be wrapped with weather-resistant
electrical tape, provided. Make sure each connector is clean and dry before
applying the electrical tape.
a. Apply electrical tape to all MS connectors, N-type connectors and any
joins in the semi-rigid coaxial cables.
b. Starting at the cable end, wrap the weather-resistant electrical tape
