Section 1: General Information
1.0 Introduction
This section provides the general information for the Teledyne Paradise Datacom High Power
Outdoor (H-Series) Solid State Power Amplifier (SSPA). This includes a description of the unit
and safety precautions.
1.1 Description
The H-Series high power outdoor SSPA contains an internal microprocessor which allows full
monitoring and control via a remote serial (RS-232 or RS-485) and Ethernet connector. The
microprocessor monitors various voltages, currents and temperatures within the unit for a full
fault analysis. The user also has the ability to select additional faults related to the RF
output level, an optional reflected RF power level and operating temperature.
An internal attenuator allows up to 20.0 dB of attenuation to be applied to the RF signal.
Temperature compensation limits the amplifier’s output response from varying significantly
over the operating temperature. Also, the system contains an output sample port.
1.2 Specifications
Refer to the specification sheet in Appendix C for complete specifications.
1.3 Equipment Supplied
The following equipment is supplied with each unit:
•

1.5 Shipment
To protect the High Power Outdoor SSPA during shipment, use high quality commercial
packing methods. When possible, use the original shipping container and its materials. Reliable commercial packing and shipping companies have facilities and materials to adequately
repack the instrument.
1.6 Safety Considerations
Potential safety hazards exist unless proper precautions are observed when working with this
unit. To ensure safe operation, the user must follow the information, cautions and warnings
provided in this manual as well as the warning labels placed on the unit itself.
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:
•
•
•
•
•
10
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.
211670 REV C
Operations Manual, High Power Outdoor SSPA
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 non-essential 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.

2.2 Installation of Unit
When installing the H-Series High Power Outdoor SSPA, consider the following:
•
•
•
•
•
There should be at least 8” clearance between the intake fans and any surface,
and 8” clearance from the SSPA’s exhaust fans.
The SSPA should never be enclosed in such a manner that restricts airflow.
Regular inspection and cleaning of the fans and heatsink is required.
Normal operating range of the SSPA is -40 to +60 °C.
The unit will start up in a muted state. To unmute the amplifier, pins V and B of Port
J4 need to be shorted.
A series of mounting holes are located along the sides of the unit that include the lifting handles, and on the sides of the unit that include the intake and exhaust fans. If utilizing the
mounting holes on the sides that include the fans, ensure the mounting brackets do not interfere with the air circulation into and out of the unit.
Warning! The SSPA should never be mounted in such a way that the intake fans face up. Doing so will void the warranty.
The H-Series High Power Outdoor SSPA weighs between 100 and 140 lbs. (45.5 - 63.6 kg),
depending on the power level of the unit. If mounting the unit to a boom or king post, ensure
the mounting brackets and surface are capable of supporting the weight of the unit. At least
two persons are required to lift the unit into position for mounting purposes.
See Appendix A for instructions on assembling a mounting frame for a redundant system
installation.

2.3.11 RF Input Sample Port (optional) [Type N (F)]
This is a Type N (F) connector which provides a coupled sample of the RF Input. A calibration label is affixed to the enclosure next to this connector.
2.4 Physical Features
In addition to the I/O connectors, the H-Series High Power Outdoor SSPA features include a
summary alarm indicator and removable fan trays.
2.4.1 Summary Alarm Indicator
A summary alarm indicator LED is located on the input side of the amplifier. When the SSPA
is operating, this indicator illuminates GREEN. When in a fault condition, it illuminates RED.
When an external mute signal is detected, the indicator will blink GREEN if operating, or RED
if the amplifier is in a fault condition.
2.4.2 Airflow and Removable Fan Trays
The H-Series High Power Outdoor amplifier’s cooling system represents a landmark in microwave telecommunication amplifiers. It features a unique system of heatsinks that have been
computer optimized to provide extremely efficient cooling of all of the system’s functional
blocks. The cooling system is based on a forced convection technique in which a series of
fans provide the air intake and exhaust.
A minimum clearance of 8 inches (203 mm) should be maintained between each fan tray and
any mounting surface. This will ensure that there is no forced re-circulation of airflow from
exhaust to intake.
The fans should be examined periodically and any obstruction or debris should be cleared.
Inadequate air flow can cause the amplifier to overheat and cause a temperature fault. See
Section 7 for instructions on how to clean the fan trays and heatsink.
In system configurations, ensure that each unit in the system has sufficient ambient airflow,
and adequate space to maintain the fans for each unit.
Spare fan assemblies are available from Teledyne Paradise Datacom. The intake fan assembly is part number L213271-1. The exhaust fan assembly is part number L213272-1, and
there are two of these per amplifier.
2.4.3 Waveguide Pressure Window (option)
Ku-Band units may be ordered with an optional waveguide pressure window at the RF Output
(J2). This option is necessary for installations where the amplifier is connected to a pressurized transmission line (up to 15 PSI).
All systems, regardless of operational band, include a pressure window at the system output
bulkhead.

3.3.1.2 Fault Status Indicators
The Fault Status frame in the lower left side of the Status Window contains a 3x4 grid of
SSPA fault lights. See Figure 3-6.
Figure 3-6: Fault Indicators
Summary Alarm: The Summary Alarm is simply a logical ‘OR’ of any major alarm indicators.
Unit Online: This is a status indicator that illuminates green when the unit is online.
External Mute Alarm: The External Mute line gives an indication that the SSPA has been
externally muted by J4-Pin B. This alarm can be configured to trigger a summary alarm if
desired. Factory default is to signal a External Mute fault but no summary alarm.
Auxiliary & Spare Alarms: The Auxiliary and Spare Alarms are configurable from the
Settings Window. These alarms can be configured to trigger a summary alarm. See Section
3.3.2.
Low DC Current Alarm: The Current Fault is factory preset to alarm if the SSPA module current falls below 60% of its nominal value. This alarm will also trigger a summary alarm.
Low DC Voltage Alarm: The Voltage Alarm is factory preset to alarm if the SSPA module
current falls below 80% of its nominal value. This alarm will also trigger a summary alarm.
High Temperature Alarm: The Temperature Fault indicator is factory preset to alarm at
80°C. The amplifier will continue to operate up to 90°C. Beyond 90°C the DC power will be
interrupted to the SSPA module. This measure will protect the sensitive microwave transistors from catastrophic failure. The fans and monitor and control circuitry will continue to operate normally. This function has approximately a 5°C hysteresis window which will allow the
amplifier to re-enable itself when the ambient temperature is reduced by 5°C. This alarm will
also trigger a summary alarm.
Forward RF Alarm: The Forward RF Fault Alarm indicates when a the RF output of the amplifier falls below the threshold set in the Settings Window.
BUC Alarm: The BUC fault is only active in units that are supplied with an optional L-Band
Block Up Converter module. If the Up Converter’s phase locked local oscillator loses lock, a
BUC alarm is set and the amplifier is muted so that spurious RF cannot be transmitted. This
alarm can be configured to trigger a summary alarm.
Operations Manual, High Power Outdoor SSPA
211670 REV C

EEPROM Alarm: The EEPROM Alarm is primarily used as a Fiber RX Link alarm for amplifier units configured with a fiber-optic interface.
RF Switch Alarms: The RF Switch 1 Alarm is only active if a 1:1 Redundant System has
been configured in the M&C program. The RF Switch 2 Alarm is only active is a 1:2 Redundant System has been configured.
3.3.1.3 Voltage, Current and Temperature Display
On the right side of the Status window is a thermometer display
that reports the present baseplate temperature of the amplifier.
The baseplate temperature typically experiences a 20-30 degree
rise above ambient on the highest power amplifiers and 15-20 degree rise on lower power units.
To the left of the thermometer display are several indicators that
show various operating conditions of the amplifier in real time.
These indicators are helpful for any diagnostic procedures and
consist of:
• Power Supply Voltage monitor
• SSPA DC Current monitor
• Regulator Voltage monitor
• Gate Voltage monitor
The Power Supply voltage indicator displays the primary 25 volt power supply output. SSPA
DC Current is the total current drawn by the microwave transistors. Regulator Voltage is the
DC voltage of the drain circuitry that feeds the GaN transistors. The Gate Voltage indicator
monitors the DC voltage of the gate circuitry of the microwave GaN transistors. These indicators provide direct access to the active device operating characteristics.
3.3.1.4 Gain Adjustment
The Gain Attenuation Control is located above the Fault Condition Indicators and below the
Carrier Enable status. The gain can be adjusted by setting the Attenuation
Control. An Attenuation Control of 0 dB is the maximum gain (75 dB) setting on
the amplifier. By setting the Attenuation Control to 20 dB; the gain is set to 55 dB.
The Attenuation Control can be varied using the control knob or the forward/
reverse buttons to the right of the displayed value.
3.3.1.5 Forward and Reflected RF Power Indicators
The Forward RF Power is displayed in the central part of the Operation
window. This indicator reports the approximate forward output power of
the amplifier. It uses the voltage from the RF Power Detector to determine a corresponding power level in dBm. The accuracy of the power
indicator is ±1 dB at the mid-point of the specified band, with a single CW or QPSK carrier.
Units with the reflected power meter option also display the Reflected RF Power.

Section 4: L Band Operation
4.0 Block Up Converter Overview
The High Power Outdoor 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 four C-Band configurations, two Ku-Band options, and one X-Band
model. See Table 4-1 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 4-1. The example in Figure 4-1 shows a 650W C-Band High
Power Outdoor SSPA with Internal Reference ZBUC. For a full description of this configuration matrix, refer to the High Power Outdoor SSPA specification sheet (211669).

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
High Power Outdoor unit.
The schematic of Figure 4-2 shows the electrical position of the block up converter. It is
powered from a +15 VDC supply available on the Fan Boost Converter board assembly. The
Block Up Converter is simply cascaded with the SSPA at the input of the amplifier.
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.

4.2 ZBUC Converter Theory of Operation
The ZBUC converter is a low gain block up converter with a typical P1dB of 0 dBm. 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 4-2.

Band selectivity is accomplished using the most aggressive filtering possible while maintaining specified power and spurious performance.
4.3 Smart Reference Technology
Teledyne Paradise Datacom’s new ZBUC converter comes standard with smart reference
technology. Smart reference technology allows the system operator to change the 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.
Note: 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 an external reference applied.
Note: The internal reference option allows for operation with either an internal or
external reference.

4.4 ZBUC FSK Monitor and Control
FSK Monitor and control comes standard with the ZBUC converter. 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 Teledyne Paradise Datacom Q-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 M&C functionality is explained
in detail in Section 8.
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:

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 4-3 gives the approximate attenuation vs. frequency for a variety of
cable types.

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 unit’s input is wrapped with a weather sealing tape to prevent water intrusion into the coaxial cable.

Section 5: Redundant System Operation
5.0 Redundant System Concepts
The High Power Outdoor Amplifier is capable of operating in a variety of redundant system
configurations. These include 1:1 and 1:2 as well as 1:1 with L-Band Block Up Converters.
The High Power Outdoor Amplifier has a built-in 1:1 redundancy controller, allowing it to be
used in 1:1 redundant systems without a separate external controller. When used in a 1:2 redundant system a separate controller, RCP2-1200, is required. The three most common
forms of 1:1 redundant system are shown in Figures 5-1 through Figure 5-3.
Figure 5-1 shows a standard 1:1 system in which the RF input is transmitted through a transfer switch along with the output. Using this configuration the standby amplifier carries no traffic and simply is terminated by a 50 ohm resistive load at its input and by a waveguide termination at its output.
Figure 5-1: Standard 1:1 Redundant System with input (coaxial) switch
and output (waveguide) switch
With the system configured as in Figure 5-2, the RF input is passed through a microwave
splitter. This keeps ‘live’ traffic on the standby amplifier and is useful for observing the traffic
via the RF sample port on the standby amplifier.
Figure 5-2: 1:1 Redundant System with input splitter substituted for input switch
Operations Manual, High Power Outdoor SSPA
211670 REV C
45
The system shown in Figure 5-3 uses the same concept of the power splitter on the RF input.
In this case the High Power Outdoor amplifiers are equipped with L-Band block up converters.
L-Band input amplifiers use phase locked oscillators as the local oscillator to the up converter.
Such systems must use a splitter at the input instead of a switch so that the reference input is
always available to the standby amplifier. If the reference signal is lost the standby amplifier
would report a BUC (Block Up Converter) fault.
Figure 5-3: 1:1 Redundant System with L Band input
Care must be taken when selecting the splitter for an L-Band input system. The splitter must
be a wide band design capable of passing the 10 MHz or 50 MHz reference signal along with
the 950 MHz to 1525 MHz traffic input. The reference frequency power level must be at least
-10 dBm into each amplifier.

5.1 High Power Outdoor Amplifier in 1:1 Redundancy
The High Power Outdoor Amplifier is ideally suited for a self-contained and cost effective 1:1
redundant system. Each amplifier has a built-in 1:1 redundant controller. The controller is
activated via computer command from the Teledyne Paradise Datacom Universal M&C
application. The High Power Outdoor Amplifier may be purchased as a redundant system or
upgraded in the field from a single thread amplifier to a 1:1 redundant system.
A redundancy kit may be purchased separately which includes the following components:
• Mounting Frame
• Waveguide Switch / Mounting Bracket
• Input Splitter
• Waveguide bends from amplifier to switch
• High Power Waveguide Termination
• Coaxial cables from splitter to Amplifier input
• Link Cable
• Switch Cable

5.1.1 Hardware Setup
The hardware setup for a High Power Outdoor 1:1 Redundant System is very simple and
involves the addition of (2) cables along with a redundancy switch. A schematic diagram of
the redundancy setup is shown in Figure 5-5.
Figure 5-5: Schematic, 1:1 Redundant High Power Outdoor System
The Link Cable is a simple (3) conductor crossover cable that allows the system to pass command and control between amplifiers. With the redundancy kit, this cable is supplied in a 26
inch (660 mm) length.
The Switch Cable is a “Tee” configuration and connects between each amplifier and the redundancy switch. The Redundancy Switch is a -28 VDC type. Therefore the controller in each
High Power Outdoor Amplifier is capable of supplying +28 VDC to the common voltage input.
Either controller may then provide a (sink) return to engage either position 1 or position 2 of
the redundancy switch.
Care must be observed when connecting this cable to the amplifiers. The cable end labeled
“A1” must be connected to the amplifier whose output is connected to Port 3 of the waveguide
switch. Likewise the cable end labeled “A2” must be connected to the amplifier whose output
is connected to Port 1 of the waveguide switch. This is for proper identification purposes of
the Redundancy Control Firmware used by each amplifier.
Note: See Appendix A for a description of installation of a 1:1 Redundant
System.

5.1.2 Software Setup
To instruct the High Power Outdoor Amplifier to operate in redundancy it is necessary to
temporarily connect it to a PC running the Teledyne Paradise Datacom Monitor and Control
Software to set up the redundant configuration. There are three basic modes of Redundant
System communication.
1. Stand-Alone 1:1 Redundant System—No Computer Control
2. PC Control using RS-232 and Paradise M&C Software
3. PC Control using RS-485 and Paradise M&C Software
5.1.2.1 Stand-Alone 1:1 Redundant System
As Method 1 implies, it is possible to have a 1:1 system operate with no PC monitor and control. Initially, however, it is necessary to connect each amplifier up to a PC to configure it for
redundant operation. Figure 5-6 shows the redundant system with each amplifier enabled to
use RS-232 communication with a PC. Every High Power Outdoor amplifier is shipped from
the factory with a “Quick Start” cable that can be used for this purpose. If the amplifiers are
purchased as a 1:1 Redundant System, this Software Setup procedure will have been set at
the factory and it is not necessary to repeat this process.

Each amplifier can be configured for redundancy by the Teledyne Paradise Datacom Universal M&C software that ships along with each unit. Using the Quick-Start cable, connect each
amplifier to the PC and run the M&C program. Select the “Settings” tab from the main form.
The “Settings” window will appear as shown in Figure 5-7.
Figure 5-7: M&C Program “SSPA Settings” window

•
System Mode: Each SSPA’s System Mode must be set to “1:1 Redundant Mode”
Hierarchical Address: Choose a Hierarchical Address for each amplifier. HPA1
means this SSPA will use RF switch position 1 as its Online state position. HPA2
will then use RF switch position 2.
Redundancy Startup State: The amplifier which is desired to be on line should be
set “Online”. The other amplifier should be set as “Standby”. Once the system is
operating, changing the state of the “Online” amplifier to “Standby” will cause the
system to drive the switch so that the other amplifier is in the “Online” state. Attempting to change the “Standby” amplifier to the “Online” state will have no effect.
This setting is saved upon unit shut-down, and the unit will start up in the last saved
state.
All settings are valid as soon as the operator sets them on the SSPA Settings window. The
SSPA’s redundant operation can be verified by monitoring the RF Switch Fault indicator as
shown in Figure 5-15.

Operations Manual, High Power Outdoor SSPA
The Standby amplifier can be muted to have a “Cold Standby” condition. It keeps the SSPA
module powered down for power savings while the microprocessor and fans remain operational. SSPAs with Parallel I/O board firmware version 3.50 or beyond are provided with a true
cold standby mode. In this mode, the SSPA will be muted automatically. Cold standby mode
has to be selected through a serial control interface (For details, see Table 10-9, data address 20).
If the Standby amplifier switches to the Online state, it will automatically un-mute and transmit
traffic. If the operator attempts to mute the Online amplifier a warning message will be displayed “You are about to mute the Online unit. Proceed with Mute?”
Similarly, connect the second amplifier to the computer’s COM port and perform the 1:1 selections on the SSPA Settings window. Just as with the first amplifier, make sure that the System mode is set to 1:1 redundant. Select a hierarchical address, HPA 1 or HPA 2 and a
startup state.
This completes the preliminary programming for 1:1 redundancy control. The amplifiers may
then be disconnected from the computer’s COM port. It is not necessary to run the Windows
based M&C software with the redundant system. The M&C software is only a convenience for
remote monitoring and control of the redundant system. The following sections detail the operation of the M&C software in 1:1 redundant system operation.

5.1.2.2 PC Control using RS232 and Paradise M&C Software
In applications requiring remote monitor and control of the redundant system, the Teledyne
Paradise Datacom Universal M&C program has a control panel that can be used for this purpose. To enable the 1:1 system to operate with the remote control software, first configure
each amplifier for 1:1 redundant operation as previously described in the Stand-Alone 1:1 Redundant System section.
When using RS232, a separate COM port will be required for each amplifier. Therefore a
computer with at least two COM ports is required for such a system. Systems using RS232
are limited by the length of the communication cable from the amplifiers to the computer. This
is typically a maximum of 30 ft. (9 m) for most RS-232 device drivers. Systems requiring longer communication cable links should use RS-485 communication.
After starting the M&C program, select [Action] > [Add Unit] > [High Power Outdoor SSPA].
See Figure 5-8. The Add New SSPA window will appear as shown in Figure 5-9.

From this screen choose the COM port and baud rate. The factory default baud rate is 9600.
If a single SSPA is used the Global network address setting should be used.
After the COM port has been selected, and the instance created, the “Status” window will be
displayed. If the SSPA is connected to a power source and turned on, the SSPA will begin
communicating with the M&C program and its operating parameters will be displayed, as
shown in Figure 5-10.
Figure 5-10: Individual SSPA Status Window
Go back to the “Add Unit” window and select the correct COM port for the second amplifier
and create the instance. Its Status window will appear on the M&C program display. If either
of the amplifiers is not communicating with the M&C Operation screen, debug the system to
find the problem. Check the RS-232 connection from each amplifier to the appropriate COM
port of the PC.
Go to the Settings tab of each unit, and set the Operational Mode to “1:1 Redundant”, the Hierarchical Address to “HPA1” and “HPA2”, and the Standby Select status to “Online” for
HPA1 and to “Standby” for HPA2.
Once reliable communication has been established between each amplifier and the computer,
the Redundancy Control Panel can be displayed. From the M&C program’s main window,
choose [Action] > [Internal Redundant System] > [1:1 Compact Outdoor SSPA System]. See
Figure 5-11.

The Redundant Control Panel window will then be displayed as shown in Figure 5-12. Note
that once the Redundant Control Panel is enabled, the Main Menu on the M&C program
changes.
The Control Panel must be configured by selecting “Set Redundancy System” and choosing
an amplifier for HPA 1 and HPA 2. Either amplifier may be designated as HPA 1 or HPA 2.
Each amplifier is identified by its ID number. The ID number is a fixed number and cannot be
changed. It is a unique encoded value determined by the particular amplifier’s model number
and serial number. If the ID number is forgotten, refer to the Status window. This window continuously displays which amplifier, by ID number, is connected to each specific COM port. After the Control Panel has been configured the display will change to the view shown in Figure
5-13.

From the Control Panel display all typical 1:1 system functions can be monitored and controlled. A particular SSPA can be put on line be selecting the command button for either amplifier. The online amplifier will be indicated by the “Online” notation. The standby amplifier will
be listed as such as shown in Figure 5-13 (Unit 2).
A particular redundant configuration can be saved by going to the “File” menu and selecting
“Save Configuration”. Thus if the program is terminated and then restarted, it will immediately
boot up with the Redundancy Control Panel display.
Each individual amplifier’s characteristics can still be monitored and controlled from its respective “Operation” window. If the user attempts to Mute an on-line amplifier, a warning window will pop-up asking if this is a valid request. See Figure 5-14.
Figure 5-14: Dialog Window, Affirm Mute of Online Amplifier
If the online amplifier enters a fault condition, the redundant switch will automatically route the
signal to the Standby amplifier. The faulted amplifier will be colored red in the Redundancy
Control Panel display. See Figure 5-15.

By clicking on the [Unit1] button (which will be labeled to correspond to the unit’s name), the
M&C Status window for Unit1 is activated, so the user may determine the cause of the fault.
See Figure 5-16. Once the fault is cleared, Unit1 can be reactivated as the online unit by
clicking on the triangular amplifier symbol for Unit2 in the System1 control panel.
Figure 5-16: Unit1 Status Panel Showing Summary and Temperature Faults
If the redundant switch is manually rotated to the offline amplifier in a redundant system, an
RF switch fault will occur. The system will not attempt to switch back to its original position.
On the Redundancy Control Panel, both amplifiers will be colored red. The switch must be
manually rotated back to the online amplifier.

5.1.2.3 PC Control using RS-485 and Paradise M&C Software
Applications requiring long cable runs between the computer and the 1:1 Redundant System
may use RS-485 communication. The amplifier firmware supports networking on a RS-485
bus. This type of network can be used to support the 1:1 Redundant System.
The RS-485 link can typically be run up to 4000 ft. (1200 m) lengths. A good quality twisted
pair cable should be used along with proper line terminations. There are no parallel end terminations in the amplifier’s RS-485 interface. Any required cable terminations have to be added
externally. Either full or half duplex RS-485 communication is supported. Schematics showing
the proper wiring of each version are shown in Figure 5-17 and Figure 5-18.
As in the stand-alone redundant system of Section 5.1.2.1, each SSPA must be programmed
for Redundant System operation by using the RS-232 interface and M&C program. Similarly
when networking SSPAs on a RS-485 network, each amplifier’s address must be set before
they can communicate over the network. Both of these steps should be performed together as
part of the initial system setup.
Figure 5-17 shows a typical 1:1 Redundant System with RS-485 Full Duplex Communication.
Figure 5-18 on the following page shows a typical 1:1 Redundant System with RS-485 Half
Duplex Communication.

5.2 High Power Outdoor SSPA in 1:2 Redundancy
The High Power Outdoor Amplifier can also be configured in 1:2 Redundant Systems. A 1:2
Redundant System typically has two transmit paths, one on a horizontal polarity and the other
on a vertical polarity. The system provides automatic switchover to the spare SSPA to either
polarization path in case of a primary SSPA malfunction. In the case of two SSPA malfunctions, the backup SSPA can be switched to either polarization path, according to a polarization priority selection setting.
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. A separate
RCP2-1200 Redundant System controller is required to provide system control. The controller
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. The controller can be remotely located from the amplifiers at a distance of up to 500 ft. (152.4 m). Figure 5-19 shows
a block diagram of a typical 1:2 Redundant System configuration.

Operations Manual, High Power Outdoor SSPA
211670 REV C
59
5.2.1 Hardware Setup
The High Power Outdoor 1:2 Redundant System uses three SSPAs mounted to a uni-strut
frame and a waveguide redundancy switch array. An indoor RCP2-1200 redundant system
controller provides monitor and control functions.
A Switch Cable connects between the controller (Port J3) and each switch in the redundancy
switch array. The redundancy switches are typically a -28 VDC type. The controller supplies
+28 VDC over this cable to the common voltage input.
A Control Cable connects between the controller (Ports J5 and J8) and each HPA (Port J4) in
the system, and is used to pass monitor and control signals.
All cable ends are marked with labels indicating to which port the connector must be mated.
For proper system operation, all cables must be properly connected.
5.2.2 Software Setup
Operational settings for amplifiers configured for use in a redundant system are typically set
up at the factory prior to shipment. If the user is using an amplifier not configured for a redundant system, the amplifier settings must be changed for such use. Temporarily connect the
amplifier to a PC running the Teledyne Paradise Datacom Universal M&C Software to set up
the redundant configuration.
There are two basic modes of 1:2 Redundant System communication.
• PC Control using RS-232 and Paradise M&C Software
• PC Control using RS-485 and Paradise M&C Software
Each High Power Outdoor amplifier is shipped from the factory with a “Quick Start” cable that
can be used to change operational parameters. Using the Quick-Start cable, connect each
amplifier to a PC running the Universal M&C software. Select the “Settings” tab from the main
form, and assign the following parameters to each HPA.

Operation Mode: Operation Mode must be set to “1:2 Redundant Mode”
Hierarchical Address: Assign a unique address for each amplifier: HPA1, HPA2
and HPA3
Standby Select: In 1:2 redundant systems, HPA2 is typically set as the standby
amplifier, with HPA1 assigned to POL1 and HPA3 assigned to POL2. Once the system is operating, changing the state of HPA1 or HPA3 to “Standby” will cause the
system to drive the switch so that HPA2 is in the “OnLine” state. Attempting to
change the “Standby” amplifier to the “OnLine” state will have no effect. This setting
is saved upon unit shut-down, and the unit will start up in the last saved state.
Standby Mode: The Standby unit can be muted to have a “Cold Standby” condition. This setting keeps the SSPA module powered down for power savings while
the microprocessor and fans remain operational. If the Standby amplifier switches
to the Online state, it will automatically un-mute and transmit traffic. If the operator
attempts to mute the Online amplifier a warning message will be displayed “You are
about to mute the Online unit. Proceed with Mute?”

Section 6: Phase Combined Systems
6.0 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 6-1 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 6-1: 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 one 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. 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.

Figure 6-2: 1:1 Fixed Phase Combined System with FPRC-1100 controller
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 6-2.
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 TWTAs. 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.
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.

6.1 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 1 RU high 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 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.
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.
The FPRC-1100 front panel is shown in Figure 6-3. 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.
Figure 6-3: FPRC-1100 Phase Combined System Controller

6.2 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 fullpower redundancy. The basic system topology is similar to a 1:2 redundant system and is
shown in Figure 6-4.
Figure 6-4: Block Diagram, 1:2 Fixed Phase Combined System
In this system, amplifiers #1 and #3 are normally online. The outputs of #1 and #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,
#2, can be switched in place of either #1 or #3 and the system maintains full output power.
The 1:2 Fixed Phase Combined System is controlled by an FPRC-1200 1:2 Redundancy
Controller. Detailed information on the installation and operation of the FPRC-1200 can be
found in the unit’s operations manual, Teledyne 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 online. This will ensure that the system is operating at full output power capability.
The output power of a phase combined system is roughly two times the output power of the
single SSPA. Some loss in the transmission line (at the switches and combiners) should be
expected which prevent a true doubling of output power.
System designers find that the 1:2 Fixed Phase Combined Amplifier System topology is a
very cost effective solution to realizing high power amplifier systems. For example, it is less
expensive to configure a 1 kW redundant system using (3) 500W amplifiers in a 1:2 Phase
Combined system than it is to use (2) 1 kW amplifiers in a traditional 1:1 Redundant System.
Note: See Appendix B for installation instructions for a 1:2 Phase Combined System.

Section 7: Maintenance and Troubleshooting
7.0 Introduction
This section describes some of the standard maintenance practices that can be performed on
the High Power Outdoor Amplifier and tips to troubleshoot common customer issues.
7.1 Cooling System Maintenance
It is recommended that the cooling system of the SSPA be checked at least once per month.
If the amplifier is being operated in an environment that produces a large amount of dust and
debris, this check should be performed more frequently.
The intake fans of the amplifier can pull airborne debris into the enclosure, and fill the spaces
between the heatsink fans. As this debris builds up inside the amplifier, the airflow which is
important in cooling the amplifier is impinged.
Blockage of the heatsink will cause the internal temperature of the amplifier module to rise
above what is considered as normal operating conditions. While the amplifiers have thermal
protection, long periods of elevated temperatures could reduce amplifier life.
The operator should visually inspect the fan intakes to make sure that they are free from any
obstruction. The Windows-based M&C program can be used to check the amplifier base plate
temperature. The base plate temperature should normally not exceed a 30°C to 35°C rise
above the outside ambient temperature. If the base plate temperature exceeds this temperature rise, it is one indicator that the system’s cooling system requires maintenance.
The heatsink fins in the exhaust path should also be visually inspected for excessive dirt and
debris buildup. If it appears there is excessive debris in the heatsink; the fan tray can be removed to access the heatsink fins for cleaning.
Warning! Failure to keep the fans and heatsink clear of debris will void
your warranty.
7.2 Fan Removal and Heatsink Cleaning
It is recommended to remove prime AC power from the amplifier when the fan trays are being
removed. However, if necessary, the fan trays can be removed while the amplifier is operating.
Warning! Use caution when handling the powered fans, to make sure that
no clothing, jewelry or body parts are caught in the fan blades.
The fans are connected to their power source by weatherized in-line circular connectors. Replacement fans with connectors can be provided for replacement.
Operations Manual, High Power Outdoor SSPA
211670 REV C

Perform the following procedure when cleaning the amplifier’s fan assemblies and heatsink.
1. Using a Philips head screw driver, loosen the thumbscrews holding the fan tray in
place. The intake fans use eight (8) thumbscrews; the exhaust fans use two (2)
thumbscrews.
2. Remove the fan tray.
3. Unplug the fan power cord from the circular MIL connector.
4. Use compressed air to dislodge any dust or debris lodged within the heatsink fins
and the fan assembly. Ensure that the heatsink fins are free from all debris.
5. Use a shop vacuum to collect all dust and debris from inside the enclosure.
6. Plug the fan power cord into the circular MIL connector.
7. Re-insert the front panel fan tray, taking care not to pinch the power cable between
the fan tray and amplifier enclosure.

7.3 Troubleshooting guide
The following section describes solutions for some of the most common issues with the
operation of the High Power Outdoor SSPA.
7.3.1 Unit doesn’t power up
Cooling fans do not spin, and alarm LED lamps are off.
Possible causes: AC power is off; Unit which requires 220V AC operation is being powered
from 110V AC grid; Unit is connected to an inadequate circuit breaker. Unit has no connection between chassis and earth ground or has inadequate earth ground.
Possible solutions: Check SSPA unit datasheet for AC power requirements. Provide the
specified AC power for the unit. Re-check continuity between unit’s chassis ground and earth
ground. Earth ground connection is required for normal SSPA operation!
7.3.2 Unit powers on, LED lamp blinks (red or green)
Possible causes: Hardware mute not disabled.
Possible solutions: Connect Mute Line Input (J4, Pin B) to Ground (J4, Pin V) to disable
hardware mute. Or, connect Quick Start cable or other properly constructed M&C cable which
jumpers J4, Pin B and J4, Pin V.
7.3.3 Unit powers on, LED lamp glows red
Possible causes: SSPA peripheral alarms (Auxiliary, Spare, Forward RF, etc.) are set as
Major alarms. Summary Alarm is caused by external reference BUC module.
Possible solutions: Connect to the SSPA unit via the Universal M&C software and disable
peripheral alarms. In the case where the unit is equipped with an externally referenced BUC,
provide the specified reference signal to the SSPA IF input.
7.3.4 SSPA unit powers up, LED lamp glows green, but no RF output signal is present
Possible causes: The SSPA is muted by an external signal or by an internal setting. The
input RF signal is too low. The input signal is out of band.
Possible solutions: Make sure the J4 connector has a jumper installed between pins B and
V (refer to Table 3-1). Connect to the unit via the Universal M&C and set the Mute setting to
Off. Check the input RF signal level and frequency. Make sure the signal properties are appropriate for the unit.

Operations Manual, High Power Outdoor SSPA
7.3.5 Cannot connect to SSPA through remote control interface
Possible causes: The SSPA remote control is set to a different interface setting. The
interface cable is not wired properly or has a broken wire harness. A PC interface port
malfunction. An incorrect version of the software is being used to control the unit. The
selected SSPA protocol is no longer supported by the SSPA firmware. In the case of RS232
interface: the wire harness is using the Chassis ground rather then a Com ground pin. In
case of IPNet or SNMP interface: PC ARP cache entry is set for different MAC/IP address
pair. Universal Handheld Controller is plugged in to Port J10.
Possible solutions:
1. In the case where SSPA communication settings have been accidentally set to a
random configuration, establish a connection to the unit with a L207755 Quick Start
cable in conjunction with the Universal M&C software (see Section 3.3.2). After
establishing a communication link with the unit, adjust the following settings to the
desired configuration: Serial Network address, Protocol Select, Baud rate (if
Normal protocol was set in in the Protocol configuration), IP address, Subnet,
Gateway, IP port and IP lock address (if IPNet or SNMP protocols were selected),
Community Set and Community Get strings (if SNMP protocol was selected), web
password (if IPNet was selected).
Disconnect the Quick start cable, and cycle AC power to the unit with the custom
cable harness plugged into the J4 M&C connector. Recheck custom control link.
2. In the case of a RS232 interface, make sure to use communication ground pin d
from the J4 connector as the RS232 ground. The SSPA RS232 port is electrically
isolated from chassis ground.
3. In the case of IPNet, use 10Base-T approved cables (CAT5, CAT6) to make a connection to the unit. Maximum cable length should not exceed 300 ft. Use Figure
3-7 as a wiring guideline. If an IP connection with custom IP addressing is desired,
don’t make any connection to interface selection pins j and e.
4. In the case of SNMP interface, make sure that the SNMP community strings match
between the SNMP NMS software and the unit. Default values for these strings
are: Public and Private. Connect to the unit via the Universal M&C to check or
change string values.
5. In the case of IPNet or SNMP protocols, clear the PC ARP cache by issuing the
following command in a Windows command line interface: arp –d.
6. Binary and Terminal protocols are no longer supported. Use the currently available
interfaces instead.
7. Serial communication over Port J4 is prevented when using the Universal
Handheld Controller plugged into Port J10. Unplug the controller to resume serial
control over Port J4.
7.3.6 The FSK link between a modem and the SSPB unit is not working
Possible cause: The unit is set to use IPNet or SNMP interface.
Possible solution: Set the SSPB protocol setting field to “Normal” protocol or (and) remove
any connection to SSPB interface select pins j and e on the J4 connector. Reset AC power.

Serial interface can be selected between RS-232/RS-485, Ethernet 10Base-T or FSK over
IFL input (FSK interface is available only on units with an optional L-Band block up converter). RS-232/RS-485 interface can be used in conjunction with Paradise Compact Outdoor
SSPA serial protocol (aka Normal protocol) or Legacy Paradise VSAT BUC serial protocol
(aka VSAT protocol). Serial protocol format is set at no parity, 8 bit with 1 stop bit. Baud rate
is selectable.
The Ethernet interface provides access to the SSPA unit over SNMP V1 protocol or a combination of HTTP web page access and Normal serial protocol encapsulated in the UDP frame
(aka IPNet). The Ethernet interface is fixed to the 10Base-T standard. Normally, straightthrough Cat5 cable is used to connect the unit to a network hub, and crossover Cat5 is used
to connect directly to a computer’s Ethernet port.
Note: The supplied Quick Start cable is a crossover cable designed to connect
the unit directly to a PC’s NIC card. Some network hubs and switches are not
equipped with an auto cable sense feature and may not work with this cable!

The selected interface is controlled by a combination of internal SSPA settings and Interface
control pins: Baud1 (Pin e) and Baud0 (Pin j) on the J4 M&C connector (See Table 8-1).

settings.
IPNet, Web, SNMP and Serial interfaces with Normal
protocol are enabled. IP Address is fixed to
192.168.0.9. Baud rate is fixed to 9600.
The operator may modify the connections to these pins to have some control over the serial
interface, bypassing EEPROM settings for Protocol, Baud Rate or Network Address. This
feature becomes important if the operator accidentally selects the wrong protocol or baud
rate of the SSPA and wants to revert the unit to a known state.
Closure to
Chassis ground
Closure to
Chassis ground
Note: The state of these pins is sensed by the SSPA unit only at power up!
Changing the state of these pins during normal unit operation will not affect the
selected type of interface.
Pins j and e have internal pull-ups and if left disconnected will remain in logic high state. The
reverting function of the SSPA is active only on initial power-up. Any alterations to the pins’
state after start-up will allow the SSPA to use internal EEPROM settings to select the baud
rate and protocol.
Pins j and e are also used for automatic addressing. To turn on automatic addressing:
1. Connect to the SSPA over serial interface;
2. Set the SSPA unique network address to 170 (Hex 0xAA);
3. Cycle the unit’s power. The unit will start up with a default baud rate of 9600 and
Standard String Protocol selection. Pins j and e now will determine the SSPA
unique address (See Table 8-2).

Operations Manual, High Power Outdoor SSPA
If it is ever necessary to revert the SSPA to a known interface state, follow the steps below:
1. Turn off the SSPA;
2. Establish wire jumpers to the M&C connector (J4) according to the desired protocol selection as shown in Table 8-1;
3. Turn on the SSPA and remove the jumpers;
4. Connect to the SSPA over serial protocol and use the Universal M&C application to
select the desired settings for protocol and baud rate. Settings will take effect on
the next SSPA power-up.
FSK interface allows the selection of Normal and VSAT protocols.
Note: For proper FSK interface operation, the SSPA internal settings must be
selected to 9600 Baud and Normal protocol. Do not make a connection to interface control pins Baud1 and Baud0!
Note: For maximum ESD protection of a SSPA’s Serial interface internal circuit,
the RS-232/RS-485 interface is isolated from the SSPA chassis ground. Serial
interface has a separate interface ground pin (Pin d on the J4 connector). Connecting this pin to common ground will effectively disable the protection circuit
and may cause interface failure.
All interface lines are equipped with transient suppression devices. Adding extra
transient protection to communication lines is not required and may cause interface failure!

8.1 Serial Communication
This section describes the normal communication protocol between the amplifier and a host
computer over RS-232/RS-485 serial interface. Serial port settings on the host computer
must be configured for 8 bit data at no parity, with 1 stop bit. The baud rate should match the
selected baud rate parameter on the SSPA unit.
Selection between the RS-232 and RS-485 interface depends on the state of pin D of the J4
M&C connector. Connect pins D and d to select RS232 interface. Otherwise SSPA will operate in RS485 mode.
The unit will only respond to properly formatted protocol packets. The basic communication
packet is shown in Figure 8-2. It consists of a Header, Data, and Trailer sub-packet.

8.1.1.1 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 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.
8.1.1.2 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 (for Indoor units) or 0xAA
(for Compact Outdoor and High Power Outdoor SSPAs). 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
SSPA unit will reply with its unique address.

8.1.1.3 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.
8.1.2 Data Packet
The data sub-packet is comprised of 6 to 32 bytes of information. It is further divided into seven fields as shown in Figure 8-4. The first six fields comprise the command preamble while

8.1.2.1 Protocol ID
This field provides backward compatibility with older generation equipment protocol. It should
normally be set to zero. This field allows the unit to auto-detect other protocol versions, which
may exist in the future.
8.1.2.2 Request ID
This is an application specific field. The amplifier will echo this byte back in the response
frame without change. This byte serves as a request tracking feature.
8.1.2.3 Command
The SSPA protocol is a table based protocol. It allows the user to view and modify data tables located on the controlled device. Throughout the remainder of this description, “sender”
will refer to the host PC, and “receiver” will refer to the SSPA unit.
Sender and receiver are limited to two commands and two command responses. The Get
Request command issued by a command sender allows monitoring of existing conditions and
parameters on the receiver. The Get Request frame should not have any bytes in the Data
Filed and be no longer than 11 bytes.
The Response frame from the receiver will contain a Get Response designator in the
Command field. If the receiver does not detect any errors in the Get Request frame, the
requested data will be attached to the response frame. The length of the Get Response
Operations Manual, High Power Outdoor SSPA

frame varies by the amount of attached data bytes. It may contain 11+N bytes where N is the
amount of requested data bytes from a particular table, specified in Data Length field.
The Set Request command allows the sender to actively change parameters for the receiver’s internal configuration. The Set Request frame must contain a number of bytes in the Data Field as specified in Data length field. The frame size must be 11+N bytes, where N is the
length of the attached data structure. The receiver will respond with a frame where the
command field will be set to a Set Response designator. The frame length is equal to the
Request frame. The byte value for each command is given in Table 8-3.

8.1.2.4 Data Tag
The SSPA internal structure is organized in several tables, all of which share similar functionality and internal resources. To access the various tables, the data tag must be specified in
the request frame. The data associated with certain tags is read only. Therefore only the
“Get” command request would be allowed to access these data tags. The SSPA will return an
error on attempts to issue a “Set” request to a read-only table tag. Various tables may contain
values formatted either in 1 or 2 bytes format. See Table 8-4.

8.1.2.5 Data Address / Error Status / Local Port Frame Length
This field is a tag extension byte and specifies the first table 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 requestor wants to access the amplifier’s
unique network address, it should set data tag 0 (System settings tag) and data address 8
(see System Settings Details table). If the following Data Length field is more than 1, then all
subsequent Settings will be accessed after the Unique Network Address.

8.1.2.6 Data Length
This byte value specifies the number of bytes attached in the Data Filed. For the Get
command, it specifies the number of data bytes that have to be returned by the SSPA unit to
a host PC in the Response frame. For Set commands, the value of this byte specifies the
number of data fields to be accessed starting from the address specified in the Data Address
byte. In general, the Data Length value plus the Data Address must not exceed the maximum
data size particular tag.
8.1.2.7 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. “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 unit. In case the data length is 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).

Figure 8-5: Trailer Sub-Packet
8.1.3.1 Frame Check
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. Checksums 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
8.1.4 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 units. 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.

8.2 Ethernet Interface
8.2.1 Overview
The amplifier supports several IP network protocols to provide a full featured remote M&C
interface over an Ethernet LAN:
1. IPNet protocol – redirection of standard Teledyne Paradise Datacom LLC serial
protocol over UDP transport layer protocol. This protocol is fully supported in Teledyne Paradise Datacom’s Universal M&C software.
2. 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 8.2.2 (IPNet Interface) and Section 8.2.4.5 (Configuring SSPA
Unit to Work with SNMP Protocol) 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.
8.2.2 IPNet Interface
8.2.2.1 General Concept
Satcom system integrators are recognizing the benefits of an Ethernet IP interface. These
benefits include:
1.
2.
3.
4.
Unsurpassed system integration capabilities;
Widely available, inexpensive 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 Teledyne 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.
Teledyne Paradise Datacom provides a WindowsTM-based control application to establish
UDP-based Ethernet communication with the SSPA. 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
Operations Manual, High Power Outdoor SSPA
211670 REV C
87
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 Teledyne 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. Teledyne Paradise Datacom recommends usage of ports 1038 and
1039. These ports are not assigned to any known application.
As an application layer protocol (which actually carries meaningful data), the standard 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 Teledyne Paradise Datacom protocol frame is
shown on Figure 8-6.

8.2.2.2 Setting IPNet Interface
To set up the amplifier with custom IP parameters, the internal IP settings need to be modified by using Teledyne Paradise Datacom’s Universal M&C, version 4.4.3 or later. See Section 3.2.4.
8.2.2.3 Troubleshooting IP Connectivity
Check IP connectivity to the SSPA unit. To do so on a Windows-based PC, open a Command
Prompt window and type the following command: PING 192.168.0.9, then press the Enter
key. If the unit is successfully found on the network, the request statistic will be displayed.

8.2.3 SNMP Interface
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 user has to enable this feature through remote serial
protocol. SNMP uses the UDP fixed port 161 for sending and receiving requests.
The definition of managed objects is described in the MIB. The MIB file is available for download from the Downloads section of the company web site, www.paradisedata.com.
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 8-11 to 8-13.
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: SystemMode'1:1=0,Dual 1:1 = 1,MSwitch=2,StandAlone=255
2. For settings or parameters with continuous values:
SettingName’LowLimit..HighLimit
Example: NetworkAddress'0..255
Note: See Section 8.3 for a description of connecting to an amplifier via a MIB
Browser.
Note: SNMP connections with the High Power Outdoor SSPA use deviceType
“cosspa(2)”.

8.2.4 Extended SNMP
High Power Outdoor units feature an extended SNMP MIB and SNMP traps. This extended
MIB covers several OID objects related to SNMP trap functions.
These units allow independent functioning of two SNMP traps (asynchronous notifications):
Fault trap and Conditions trap. Both traps can be enabled or disabled by the user. The user
can also specify how many times the same trap notification will be sent back to the SNMP
manager.
The SNMP manager IP address is also selectable by the user. This IP address must be specified in the relevant OID branch.
Every trap message is marked by the fixed trap community string: “trap”. This community
name is not user selectable.
The Fault Trap allows asynchronous notification of the SSPA fault state change. When enabled, trap notification will be sent to a manager every time either the summary fault state or a
fault type is changed. The Last Fault Time ticks counter will be reset each time the summary
fault changes its state to “Alarm” or when a new fault condition is detected. This counter also
resets itself during device power-up. If no faults are present after device power-up, Fault Trap
will issue a “Cold Start” notification to the manager.
The Condition Trap allows the unit to generate asynchronous notifications independent from
the unit fault state. Currently, the following conditions can be used for this trap triggering:
Forward RF Level, Reflected RF Level (for units equipped with a Reflected RF sensor), DC
Current level, PS Voltage level, module plate temperature, and LNA current (if an external
LNA is powered through the SSPA auxiliary power port).
To enable this trap, set the Condition Trap Resend option to a non-zero value and determine
the upper and lower limits for the condition window. Window values must be selected according to the relevant selected condition measured by the unit. For example: Temperature must
be selected in degrees, RF power in tenth of dBms, etc.
After successful configuration, the SSPA will generate a notification every time the selected
condition is outside the selected measurement window. For units with multiple measured parameters, the relevant condition location must be selected (i.e., units with two power supplies
use 1 for PS1, and 2 for PS2). For other conditions, this value is “don’t care”.
Both traps will send a “Device Up Time” time stamp with every trap notification.

8.3 M&C via SNMP
Set up the amplifier with custom IP parameters by modifying the internal IP settings using
Teledyne Paradise Datacom’s Universal M&C, version 4.4.3 or later. Use the default Read
and Write Community settings, or check the boxes to modify them. See Figure 8-7.
The Protocol setting in the Settings tab of the Universal M&C needs to be set to SNMP, as
shown in Figure 8-8.
SNMP
Figure 8-7: Universal M&C, IP Setup tab
Figure 8-8: Universal M&C, Settings tab
After the desired IP address, Subnet mask and Gateway parameters have been set, the unit
will still use its default parameters. To make the new parameters active, reset the amplifier by
removing its AC power. Unplug the Quick Start cable from the M&C connector. (If the unit is
restarted with the Quick Start cable connected, it will always come up with default IP
settings). Apply power to the SSPA. Re-plug the Quick Start cable into J4, and check
connectivity with the custom IP settings.
If the custom IP settings will be used in normal operation, the user must construct an IP cable
or modify the Quick Start cable by disconnecting the interface control pins (pins j and e, Baud
Select 0 and Baud Select 1) from ground. In this configuration, the SSPA will always use the
saved communication control settings rather then rolling back to the default configuration.

8.3.2 SNMP V3 implementation 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.
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, access 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, 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 (SNMP V1, described in RFC 1157) is the initial implementation of SNMP.
Version 2 (SNMP V2c, described in RFC 1902) is the second release of SNMP. It provides
additions to data types, counter size, and protocol operations.
Version 3 (SNMP V3, 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 Datagram-Delivery Protocol (DDP), and
Novell Internet Packet Exchange (IPX). SNMPv1 is widely used and is the de-facto networkmanagement 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
102
211670 REV C
Operations Manual, High Power Outdoor SSPA
introduced GetBulkRequest, an alternative to iterative GetNextRequests for retrieving large
amounts of management data in a single request. 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 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.
Problems with implementing SNMP V2 and V3 in Teledyne Paradise Datacom SSPA product
family
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 informs. Traps are unreliable
because the receiver does not send acknowledgments when it 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 PDU. If the sender never receives the response, the inform
request can be sent again. Thus, 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. Also, a
trap is sent only once, while an inform may be retried several times. The retries
increase traffic and contribute to a higher overhead on the network.

Universal Handheld Controller
9.0 Overview, RCH-1000
Teledyne Paradise Datacom’s Universal Handheld Controller (model RCH-1000) is a versatile device used to interface with a High Power Outdoor SSPA.
The device enclosure features a seal which provides an ingress protection level of IP65. This
allows the controller to be used in most outdoor environments. The enclosure’s rugged construction provides protection from impact and vibration.
When connected to a High Power Outdoor SSPA, this device allows the operator to adjust
the attenuation of the connected unit, control the mute/unmute selection, and monitor the
status, conditions and settings of the connected unit via a serial RS-485 connection. Faults
and other events are tracked in the controller’s internal log.
The front panel of the controller features six light emitting diodes, eight keys and a 2.5 in. x
1.3 in. OLED display. See Figure 9-1.

Appendix A: Installation, Uni-Strut Frame
for 1:1 Redundant System Mounting
A.1 Introduction
This section outlines the assembly and mounting procedure for a 1:1 Redundant High Power
Outdoor SSPA System.
Before beginning the assembly of the uni-strut mounting kit, verify that the kit includes all of
the items in Table A-1. If any items are missing, contact Teledyne Paradise Datacom with the
part number and quantity of the shortage.
The following instructions describe the assembly of the uni-strut mounting kit, and the installation of the High Power Outdoor SSPAs and associated switch and waveguide assembly. The
system is intended to be free standing and entirely self-supported once properly mounted.
It is important to give consideration to the following:
1. Structural integrity of the mounting deck.
2. Accessibility to all local user interfaces. (Ensure SSPA enclosure doors are free to
open to the latched position.)
3. Adequate cooling air, 8.00” minimum clearance must be maintained between air
intake and any surface that will inhibit air flow.
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. Proper weatherized sealing of all connectors.
Warning! The High Power Outdoor SSPAs 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.

Appendix B: Installation, Uni-Strut Frame
for 1:2 Phase Combined System Mounting
B.1 Introduction
This section outlines the assembly and mounting procedure for a 1:2 Phase Combined High
Power Outdoor SSPA System.
Before beginning the assembly of the uni-strut mounting kit, verify that the kit includes all of
the items in Table B-1. If any items are missing, contact Teledyne Paradise Datacom with the
part number and quantity of the shortage.
The following instructions describe the assembly of the uni-strut mounting kit, and the installation of the High Power Outdoor SSPAs and associated switch, signal box and waveguide assembly. The system is intended to be free standing and entirely self-supported once properly
mounted.
It is important to give consideration to the following:
1. Structural integrity of the mounting deck.
2. Accessibility to all local user interfaces. (Ensure SSPA enclosure doors are free to
open to the latched position.)
3. Adequate cooling air, 8.00” minimum clearance must be maintained between air
intake and any surface that will inhibit air flow.
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. Proper weatherized sealing of all connectors.
Warning! The High Power Outdoor SSPAs 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.
