Installation Guidelines Regarding Power Line Quality
Comtech EF Data has become familiar with the varying quality of the AC power grid
around the world. Observing the following installation guidelines should help ensure
a reliable installation.
•
Grounding: The HPOD provides a grounding terminal to allow you to ground the HPOD to
the antenna’s grounding network. All components installed at the antenna should be
grounded to a common grounding point at the antenna.
•
Surge suppression: High voltage surges can cause failure of the power supply. The cause of
such surges typically includes circuit switching on the main AC power grid, erratic generator
operation, as well as lightning strikes.
While the HPOD features built-in surge suppression, if installation is to be in a location with
questionable power grid quality, Comtech EF Data recommends installation of additional
power conditioning/surge suppression at the power junction box.
Lightning strikes on or around the antenna will generate extremely high voltages on all
cables connected to the HPOD. Depending on the severity of the strike, the HPOD’s internal
surge protection combined with the recommended external suppression may protect the
HPOD’s power supply. However, if installation is in an area with a high probability of
lightning strikes, Comtech EF Data additionally recommends the installation of surge
suppression on the RF and IF cables. One source of these suppressors is PolyPhaser
(2Hwww.polyphaser.com).
•
Electrical welding: If welding needs to take place at the antenna, disconnect all cables from
the HPOD except for the ground wire. Cap all RF connections with terminations. This will
prevent damage to the input/output circuitry of the HPOD.

Overview
Figure 1-1. Comtech EF Data HPOD SSPA
Comtech EF Data’s High-Power Outdoor (HPOD) Solid-State Power Amplifier (SSPA) (Figure 1-1)
delivers its rated power, guaranteed, at the 1 dB compression point, to the transmit waveguide
flange. It provides a cost effective, more reliable replacement for Traveling Wave Tube Amplifiers
(TWTA) in satellite communications.

Features
The HPOD SSPA base unit provides features that are typically offered as options elsewhere. Its
features include temperature compensation, sample ports, power monitor, field-replaceable
power factor-corrected power supply, and full remote monitor and control capabilities. Higher
power is available through the use of CEFD 1:1 and 1:2 phase combining kits.
1.2
•
Solid-State Advantage: Each HPOD is constructed with highly reliable gallium arsenide
(GaAs) FETs. With third order intermodulation products from 4 dB to 6 dB better than TWTA
ratings, the HPOD replaces TWTAs with saturated power levels of up to twice the HPOD’s
rated output. The HPODs also provide a mean time between failures (MTBF) that is 4 to 5
times greater than the typical TWTA MTBF.
•
Field-Replaceable Power Supply: Recognizing that the MTBF limiting factor for almost all
electronic equipment is the power supply, the HPOD provides for easy field replacement.
Simply disconnect the AC mains, release the captive fasteners, and remove the supply from
the SSPA module.
•
Built-in Redundancy Controller: Each HPOD has the ability to function as a 1+1 (one backup
for one primary) and 1+2 (one backup for two primaries) redundancy controller in the
backup mode. The optional redundancy configuration is implemented by attaching a ganged
waveguide/coax transfer switch(es) to the input and output connectors of the amplifiers
with a combination coaxial cable and waveguide kit. When the backup SSPA is commanded
into the controller mode, it monitors the online SSPA(s) for faults. A faulted online unit may
be disconnected and replaced without affecting the online power amplifier.
•
Phase Combining: Comtech EF Data’s phase-combined systems allow the outputs of two
amplifiers to be summed together. A “normal” 1:1 system using 300W amplifiers provides
300W of output power (the offline unit’s capabilities are unusable). The same amplifiers in a
1:1 phase-combined system provide 600W of output power in normal operation, and a “soft
failure” state of 300W. If no degradation on failure can be accommodated, a third amplifier
can be added to form a 1:2 phase-combined system.
•
Optional “Smart BUC” Functionality: Comtech EF Data’s unique approach to L-Band/RF
frequency conversions eliminates DC and 10 MHz from the input coax. This simplifies
redundancy and multi-carrier operation. It offers full 13.75 GHz to 14.5 GHz Ku-Band
coverage and supports industry standard FSK modem/BUC communications. The optional
BUC can lock to an external or internal reference oscillator.
Functional Description
Each HPOD consists of a CEFD SSPA module with a field replaceable power supply, a field
replaceable fan assembly, and the Monitor/Control Processor (MCP). The amplifier features a
Comtech EF Data low loss combining technique and MCP based temperature versus gain
compensation.

Introduction

MN/HPOD.IOM
Revision 8
SSPA Module
The amplifier module performs the core function of the unit. An isolator is at the RF input to
ensure good VSWR. The RF signal then passes through an input sample port and on to an
electronically controlled attenuator that adjusts the overall attenuation according to the user
input. After some amplification, a second attenuator is automatically controlled via a look-up
table to maintain the amplifier gain at a constant level over temperature variations.
The RF signal is then amplified by a multi-stage design that utilizes proprietary combining
techniques to meet the rated power requirements. The output circuitry contains a coupler to
provide a sampled signal for monitoring purposes. A power detector circuit also is included and
the reading is accessible via remote communication. A high power circulator and load is located
at the output to provide good VSWR and protection from external mismatch.
1.3.2
Power Supply
The SSPA features a removable power supply that is also power factor corrected. It connects to
the main chassis via a specialized connector capable of the required high current. It supplies
several voltages necessary for the unit to operate. The 10V output is capable of 2000W and
supplies current to the power transistors in the RF amplifier module via two paths, or cables
(10V A and 10V B). Circuitry within the RF module controls the output status of this power
supply. If the RF module does not have the –5V supply for any reason, it does not allow the 10V
power supply to turn on. This protects the power transistors within the RF module from failure
due to improper power supply sequencing. The +24V output powers the cooling fans and is the
source of power for waveguide switching when the SSPA is used in redundancy configurations.
The +5V and +15V voltages are used to operate the M&C board and other overhead functions.
1.3.3
Cooling System
The SSPA unit contains a robust heat sink and thermal design to maintain a low operating
temperature. Two temperature-controlled fans, which are monitored by the M&C board, draw
cool outside air in across the power supply and specialized heat sink and exhaust the warmer air
out the bottom of the unit. The amplifier module temperature is monitored, and if for any
reason the amplifier temperature exceeds a safe preset limit, the amplifier module supply is
shut down to protect the unit from thermal failure.
1.3.4
Monitor and Control (M&C)
The unit includes a microprocessor-based system that provides monitoring and control of the
essential parameters of the unit. The user interfaces with the unit through the M&C system via
the J6 | COM1 remote control/discrete communications port. The unit is capable of EIA-232,
EIA-485 or Ethernet remote communication. A discrete mute control and relay status output is
also available.
The M&C system monitors the fan speed, unit temperature, all power supply voltages, power
transistor currents, output power, etc. Should a critical monitored parameter fail, the unit will
1–5

Revision 8
mute the RF signal and report a fault. The details of the fault can be accessed via remote
communication.
The M&C is also capable of acting as a controller in certain 1:1 or 1:2 redundancy systems. When
configured as the back-up SSPA in such a system, it communicates with the other SSPA(s) and
toggles the waveguide switches as necessary.
1.3.5
Block Up Converter Input Option
The HPOD amplifier, when delivered from the factory with an internal Block Up Converter (BUC),
translates an L-Band input carrier to the desired output frequency (C-, X-, or Ku-). Local
Oscillator (LO) frequencies are as follows:
BUC-4000 C, X, Ku, Ka
Band
Frequency

7900 MHz-to-8400 MHz
6950 MHz
No
Ku-Band-W
13.75 GHz-to-14.50 GHz
12.800 GHz
No
The same Ku-Band BUC is installed independent of amplifier bandwidth. Therefore, the
“standard” 14.0 GHz-to-14.5 GHz HPOD has an L-Band frequency range of 1200 MHz-to-1700
MHz that translates up to 14.0 GHz-to-14.5 GHz, while the “Extended” 13.75 GHz-to-14.5 GHz
HPOD translates L-Band frequencies from 950 MHz-to-1700 MHz up to 13.75 GHz-to-14.5 GHz.
Unlike most BUCs, no DC bias voltage should be provided on the center conductor of the L-Band
coax.
In addition, the BUC version of the HPOD is available with an internal 10 MHz reference. As,
such, no 10 MHz reference is required on the center conductor of the L-Band coax. If a reference
is provided on the coax, the internal reference will detect and lock to it.

4.1
Overview
This chapter describes the functionality of the HPOD Ethernet (HTTP) Interface. Ethernet-based
Remote Product Management of the HPOD is available using the ‘J6 | COM1’’ port.
To proceed with Ethernet-based Remote Product Management, assumptions are
made that:
•
The HPOD is operating with the latest version firmware files.
•
The HPOD is connected to a user-supplied Windows-based PC as follows:
•
o
The PC’s Ethernet port is connected to the HPOD ‘J6 | COM1’ port with a
190-pin to RJ-45 adapter cable.
o
The PC is running a terminal emulation program (for operation of the HPOD
remote control Telnet interface) and a compatible web browser (for
operation of the HPOD Web Server Interface).
The HPOD IP Address has been noted using the HPOD remote serial or Telnet
‘FRW’ query or by using the HPOD Web Server Interface Admin | Access page.
See the Remote Commands and Queries specifications tables found in Chapter 5.

Ethernet Management Interface Protocols
The user PC facilitates access to Ethernet-based remote monitor and control (M&C) of the HPOD
through three separately operated protocols:
4.3
•
Simple Network Management Protocol (SNMP). This non-secure interface requires a usersupplied Network Management System (NMS) and a user-supplied Management
Information Base (MIB) File Browser.
•
Telnet Interface. This non-secure interface requires use of the user PC’s Command-line
interface, or a user-supplied terminal emulation program such as HyperTerminal.
•
HPOD Web Server (HTTP) Interface. This non-secure interface requires a compatible usersupplied web browser such as Internet Explorer.
SNMP Interface
The Simple Network Management Protocol (SNMP) is an Internet-standard protocol for managing
devices on IP networks. An SNMP-managed network consists of three key components:
•
The managed device. This includes the HPOD.
•
The SNMP Agent. This is the software that runs on the HPOD. The HPOD SNMP Agent
supports both SNMPv1 and SNMPv2c.
•
The user-supplied Network Management System (NMS). This is the software that runs on
the manager.
4.3.1 Management Information Base (MIB) Files
The following MIB files are associated with the HPOD:
MIB File/Name (where ‘x’
is revision letter)
Description
FW-0020546x.mib
ComtechEFData Root
MIB file
ComtechEFData MIB file gives the root tree for ALL Comtech EF Data HPOD
products (PSx) and consists of only the following OID:
FW-0020547x.mib
HPOD MIB file
MIB file consists of all of the OIDs for management of the HPOD functions
FW-0020548x.mib
HPOD Traps MIB file
Trap MIB file is provided for SNMPv1 traps common for HPOD.

MN/HPOD.IOM
Revision 8
An MIB file is used for SNMP remote management of a unique device, and consist of a tree of
nodes called Object Identifiers (OIDs). Each OID provides remote management of a particular
function.
Compile these MIB files in a user-supplied MIB Browser or SNMP Network Monitoring System
server.
4.3.2 SNMP Community Strings
In SNMP v1/v2c, the SNMP Community String is sent unencrypted in the SNMP
packets. Caution must be taken by the network administrator to ensure that SNMP
packets travel only over a secure and private network if security is a concern.
The HPOD uses Community Strings as a password scheme that provides authentication before
gaining access to the router agent’s MIBs. They are used to authenticate users and determine
access privileges to the SNMP agent.
Type the SNMP Community String into the user-supplied MIB Browser or Network Node `
Management software.
Three Community Strings are defined for SNMP access:
•
Read Community
•
Write Community default = private
•
Trap Community
default = public
default = comtech
For proper SNMP operation, the HPOD MIB files must be used with the associated
version of the HPOD M&C. Please refer to the HPOD FW Release Notes for
information on the required FW/SW compatibility.
4.3.3 SNMP Traps
The HPOD sends out SNMP traps both when a fault occurs and when it is cleared.
1) The SNMP agent supports SNMP v1 and v2c.
2) If SNMP v1 traps are to be used, then make sure to compile the traps file.
Use the hpodSNMPTrapVersion OID to configure the type of traps that the HPOD will send.
The HPOD uses these MIB2 v1 traps and v2 notifications:
MIB2 SNMPv1 trap: Authentication Failure

4.4.1 Telnet Operation via HyperTerminal
There is a disadvantage when using Windows Command-line as a Telnet client. Since Commandline cannot translate a ‘\r’ (i.e., carriage return or “CR”) to a ‘\r\n’ (i.e., CR+line feed “LF”) for the
messages coming from Telnet Server, any multi-line Target-to-Controller response (e.g., the
response to the FRW? query) will be displayed as one line, with the latter lines overwriting the
previous lines.
In order to view the full response messages, Comtech EF Data recommends use of the
HyperTerminal terminal emulation program, configured as a Telnet client.
Configure HyperTerminal as follows:
1) Ensure that the connection is
made using TCP/IP (Winsock)
instead of COM1 or COM2, as
shown at the near right.
2) ASCII Setup (File  Properties 
Settings  ASCII Setup): Check
the "Send line ends with line
feeds" option in the ASCII Sending
section, and the "Append line
feeds to incoming line ends"
option in the ASCII Receiving
section, as shown at the far right.

HPOD Web Server (HTTP) Interface
A user-supplied web browser allows the full monitor and control (M&C) of the HPOD from its
embedded Web Server Interface. This application is designed for, and works best with,
Microsoft’s Internet Explorer Version 5.5 or higher.
4.5.1 Enable the Web Server Interface
Follow these steps to enable the HPOD Web Server Interface using only a 10/100BaseT remote
interface and a Microsoft Windows operating system.
1) Select Start, then Run, then type “cmd” to open the command prompt window:
2) Start a Telnet session with the unit at the default IP address of 192.168.1.4:

Revision 8
3) Enter the User name and password (the default for both is comtech):
4) Use the LRS remote command to set the Ethernet remote control access parameter:
•
Use default remote command LRS=3 for Serial + Ethernet control
•
Use remote command LRS=2 for Ethernet control only.
5) If necessary, use the IPA remote command to set a unique IP address.
1) Each HPOD must have a unique IP address assigned before connection
to a network. If the IP address needs to be changed from the factory
default setting, use the IPA=xxx.xxx.xxx.xxx.yy remote command,
where ‘xxx.xxx.xxx.xxx’ is a valid IP address on the network where the
unit will be installed, and ‘yy’ is the range (typically, yy=24).
2) If you change the IPA value, make sure to shut off and restart the unit;
then, start a new Telnet session using the new IP address.

Chapter 5. SERIAL-BASED REMOTE PRODUCT
MANAGEMENT
5.1
Overview
This chapter describes the protocol and message command and query set for complete remote monitor and control of the HPOD SSPA. It
also summarizes key operational parameters and some of their most commonly-used remote commands and queries.
5.2
Key Operational Parameters
See Sect.5.5 Remote Commands and Queries for detailed information about the remote commands and queries mentioned
in this section.
5.2.1 RF Input Level
The individual amplifier maximum gain and power rating determines the RF input level required to reach the full rated output power of
the HPOD.
For example: If the test data of an SSPA rated for 250W (54 dBm) indicated a gain of 75 dB, then a signal of 54dBm – 75 dB = -21 dBm
would approximately give the rated output power.
Increasing input power beyond this level results in an output signal with increasingly higher levels of distortion. Of course, if the SSPA
attenuation control is utilized, a higher-level input signal level can be accommodated.
5–1
HPOD C-, X-, Ku-Band High-Power Outdoor Amplifier
Serial-Based Remote Product Management
MN/HPOD.IOM
Revision 8
CAUTION – Permanent damage may occur to the unit if the maximum input level exceeds 15 dBm.
5.2.2 Attenuator Control
Execute the “ATT” command to attenuate HPOD gain over a 30 dB range.
5.2.3 Mute Control
The HPOD may be muted via software or discrete control:
•
Software – Exercising the MUT=1 command will “software” mute the unit.
•
Discrete Control – When exercising the AUX=1 command, the HPOD will be muted until Pin ‘S’ (on the ‘J6 | COM1’ Discrete Control
Connector) is pulled to ground (Pin ‘K’). At that time, the unit unmutes.
The Mute command provides over 60 dB of RF on/off isolation. However, the Mute command only turns off the first few low power
stages of the amplifier, the high power stages remain on. By allowing the higher power transistors to stay on, the HPOD remains in a
more thermally stable state should the mute condition be removed.
If the user desires to completely turn off the bias to the entire amplifier (perhaps to conserve energy in a redundant system), both the
MUT=1 and AMP=0 commands should be executed. For normal transmit operation, MUT=0 and AMP=1 are required.
5.2.4 Faults
The M&C system monitors certain key functions of the SSPA for proper operation. Should any of these operating parameters exceed
predetermined limits, the M&C system will declare a fault. Conditions that trigger a fault include:
•
Any power supply more than ± 10% outside its nominal value.
•
Either fan less than 25% of maximum speed.
5–2
HPOD C-, X-, Ku-Band High-Power Outdoor Amplifier
Serial-Based Remote Product Management
MN/HPOD.IOM
Revision 8
•
I2C internal bus communications fault.
•
Thermal Shutdown. The system indicates a temperature fault if the unit is ≥ +95°C. This creates a summary fault and causes the unit
to mute itself, and switch to the backup unit if in a redundancy system. However, the 10V supply to the Field Effect Transistors (FETs)
will remain on until the unit reaches the thermal shutdown temperature of ≥ 100°C. For protection reasons, the unit will shut down
the 10V supply to the power transistors at temperatures ≥ 100°C.
5.2.5 Power Detector
The HPOD features a power detector to monitor the output power. It has a useful range of over 20 dB, referenced to the unit’s rated
P1dB point. To read its value, execute the “RMS” query (e.g., <1/RMS?<cr>). The test data supplied with each unit gives an indication of
the accuracy and flatness of the power monitor over the frequency band of operation.
5.2.6 Most Common Remote Queries
5.3
•
RMS (Retrieve Maintenance Status): Displays voltages, fan speeds, Heatsink temperature, output power monitor reading, etc.
•
RCS (Retrieve Configuration Status): Displays current attenuation, mute, amplifier, online, etc. status.
•
RAS (Retrieve Alarm Status): Displays current alarm or fault status.
Serial Remote Control Introduction
Serial-based Remote Product Management of the HPOD is available via its J6 | COM1 port. This interface is either an EIA-485 multi-drop
bus (for the control of multiple devices) or an EIA-232 connection (for the control of a single device). The interface transmits data in
asynchronous serial form, using ASCII characters. This data consists of control and status information, transmitted in packets of variable
length in accordance with the structure and protocol explained later in this chapter.
5.3.1 EIA-485
For applications where multiple devices are to be monitored and controlled, full-duplex (4-wire plus ground) EIA-485 is preferred. Halfduplex (2-wire plus ground) EIA-485 is possible, but is not preferred. In full-duplex EIA-485 communication, there are two separate,
isolated, independent, differential-mode twisted pairs, each handling serial data in different directions.
5–3

Revision 8
It is assumed that a 'Controller' device (a PC or ASCII dumb terminal) transmits data in a broadcast mode via one of the pairs. Multiple
'Target' devices are connected to this pair, and all simultaneously receive data from the Controller. The Controller is the only device with
a line-driver connected to this pair – the Target devices have only line-receivers connected.
In the other direction, on the other pair each Target has a Tri-state line driver connected, and the Controller has a line-receiver
connected. All the line drivers are held in high-impedance mode until one (and only one) Target transmits back to the Controller. Each
Target has a unique address, and each time the Controller transmits, the address of the intended recipient Target is included in a framed
'packet' of data. All of the Targets receive the packet, but only one (the intended) will reply. The Target enables its output line driver and
transmits its return data packet back to the Controller in the other direction, on the physically separate pair.
EIA-485 (full duplex) summary:
•
Two differential pairs – one pair for Controller-to-Target, one pair for Target-to-Controller.
•
Controller-to-Target pair has one line driver (Controller), and all Targets have line-receivers.
•
Target-to-Controller pair has one line receiver (Controller), and all Targets have Tri-State drivers.
5.3.2 EIA-232
This is a much simpler configuration in which the Controller device is connected directly to the Target via a two-wire-plus-ground
connection. Controller-to-Target data is carried via EIA-232 electrical levels on one conductor, and Target-to-Controller data is carried in
the other direction on the other conductor.
5.3.3 Basic Protocol
Whether in EIA-232 or EIA-485 mode, all data is transmitted as asynchronous serial characters, suitable for transmission and reception
by a Universal Asynchronous Receiver/Transmitter (UART). The asynchronous character format is 8-N-1 (8 data bits, no parity, 1 stop bit).
The baud rate may vary from 1200 to 19200 baud.
All data is transmitted in framed packets. The Controller (assumed to be a PC or ASCII dumb terminal) that is in charge of the process of
monitor and control is the only device that is permitted to initiate, at will, the transmission of data. Targets are only permitted to
transmit when they have been specifically instructed to do so by the Controller.

Revision 8
All bytes within a packet are printable ASCII characters, less than ASCII code 127. In this context, the Carriage Return and Line Feed
characters are considered printable.
All messages from Controller-to-Target require a response, with one exception: This will be either to return data that has been
requested by the Controller, or to acknowledge reception of an instruction to change the configuration of the Target. The exception to
this is when the Controller broadcasts a message (such as Set Time/Date) using Address 0, when the Target is set to EIA-485 mode.

Revision 8
Start of Packet
•
Controller-to-Target – This is the character ‘<’ (ASCII code 60).
•
Target-to-Controller – This is the character ‘>’ (ASCII code 62).
The ‘<’ and ‘>’ characters indicate the start of packet. They may not appear anywhere else within the body of the message.
5.3.4.2
Target Address
Up to 9,999 devices can be uniquely addressed; in both EIA-485 and EIA-232 applications, the permissible range of values is 1 to 9999.
The address is programmed into a Target unit using the remote control port.
The Controller sends a packet with the address of a Target – the destination of the packet. When the Target responds, the
address used is the same address, to indicate to the Controller the source of the packet. The Controller does not have its
own address.
5.3.4.3
Address Delimiter
This is the “forward slash” character '/ ' (ASCII code 47).
5.3.4.4
Instruction Code
This is a three-character alphabetic sequence that identifies the message subject. Wherever possible, the instruction codes have been
chosen to have some significance to aid in the readability of the message, should it be displayed in its raw ASCII form. Only upper case
and lower case alphabetic characters may be used (A-Z, ASCII codes 65-90).
5.3.4.5
Instruction Code Qualifier
This is a single character that further qualifies the preceding instruction code. Code Qualifiers obey the following rules:
1) From Controller-to-Target, the only permitted characters are:

Revision 8
Character
Definition
=
(ASCII code 61)
This character is used as the Assignment Operator (AO). It establishes that the Instruction Code that precedes it is to be used as a
command to assign or configure operation. The instruction set that follows serves to assign the Target’s new parameter setting or
operational value. Example: From Controller-to-Target, MUT=1 means “enable the mute function.”
?
(ASCII code 63)
This character is used as the Query Operator (QO). It establishes that the Instruction Code that precedes it is to be used as a query
that returns the Target’s current configured parameter setting or operational value. Example: From Controller-to-Target, MUT?
means “what’s the current state of the MUTE function?”
2) From Target-to-Controller, the only permitted characters are:
Character
Definition
=
(ASCII code 61)
This character is used in two ways:
a. If the Controller sends a query to the Target – for example: MUT? meaning “what’s the current state of the MUTE function?”, the
Target would respond with MUT=x, where x represents the state in question: 1 being enabled, and 0 being disabled.
b. If the Controller sends an instruction to set a parameter to a particular value, and the value sent is valid, the Target acknowledges
the message and responds with MUT= (with no message arguments).
?
(ASCII code 63)
If the Controller sends an instruction to set a parameter to a particular value, and the value sent is not valid, the Target then
acknowledges the message and responds with, for example, MUT? (with no message arguments). This indicates that there was an
error in the message sent by the Controller.
!
(ASCII code 33)
If the Controller sends an instruction code that the Target does not recognize, the Target responds by echoing the invalid instruction,
followed by ! Example: XYZ!
*
(ASCII code 42)
If the Controller sends the command to set a parameter to a particular value, and the value sent is valid BUT the router will not permit
that particular parameter to be changed at present, the Target acknowledges the message and responds with, for example, MUT* (with
message arguments).
#
(ASCII code 35)
If the Controller sends an instruction code which the Target cannot currently perform because of hardware resource issues, then the
Target will acknowledge the message by echoing the invalid instruction, followed by the # character. This response can only occur if the
operator sends two or more ‘hardware configuration’ type commands without allowing adequate time between commands for the
hardware to be configured. For example, if the operator issued commands to change both the frequency and the attenuation with less
than 100 milliseconds between commands, and if this response is returned, then the command has not been accepted and the operator
must resend the command.

REDUNDANCY OPERATION
B.1
Overview
Comtech EF Data’s C-, X-, and KU-Band High-Power Outdoor Power Amplifiers (HPODs) can be
used in redundant configuration by connecting the appropriate redundancy loop cable between
the user M&C location and each HPOD ‘J4 | REDUNDANT LOOP’ port. This 1:1 or 1:2 cable has
connector pinouts that allow the HPODs to both automatically detect the type of cable in use
and, when properly connected between the user and the redundancy setup, automatically
configure itself for operations in accordance with the labeling for each cable connector (SSPA 1
or SSPA 2 for a 1:1 system, or SSPA 1, SSPA 2, or SSPA BU for a 1:2 system).
B.1.1 1:1 Redundancy Mode
In 1:1 redundancy mode, the unit that is currently not the active unit (determined by the switch
position) will be the controlling Backup Unit (BU).
The redundancy system’s operating mode is determined by using the “RAM” serial remote
command:
•
If RAM=1 i set in both units, the system will be in “AUTO” redundancy mode. In this mode, if
a fault is detected with the active unit – either by loss of communications between the
offline and online unit or via the summary fault – the backup (offline) unit will switch the
waveguide switch and become the active(online) unit (assuming the backup unit is not
faulted).
•
If RAM=0 is set in both units, the system is set to “MANUAL” redundancy mode, and no
switchovers will occur upon fault detection.
Switch position is determined by using the “SSW” serial remote command:
•
SSW=1 sets the switch to put SSPA 1 online;
•
SSW=2 sets the switch to put SSPA 2 online.
B–1
HPOD C-, X-, Ku-Band High-Power Outdoor Amplifier
Appendix B
MN/HPOD.IOM
Revision 8
In 1:1 applications, the BU also stores an offset value, to be used when the BU replaces the
active unit. This offset may be set with the GOF= command. When the online unit is being
“backed up” the BU’s attenuator will be set to this value. This value may be different than the
attenuation value of the online unit to compensate for any gain mismatch between the BU and
online units.
To calibrate, do these steps:
Step
Task
1
Identify the unit with the most gain.
2
Calculate the actual error.
3
To compensate for the error, set the GOF= command in the unit having the highest error. For example – If
SSPA 1 has 70 dB of gain, and BU SSPA 2 has 72 dB, send the GOF=2.00 command to the BU SSPA 2 to
store these values.
B.1.2 1:2 Redundancy Mode
Figure B-1 shows the block diagram for an HPOD 1:2 Redundancy System. For the purpose of
example, this figure shows a C-Band system.
Figure B-1. HPOD C-Band 1:2 Redundancy System Block Diagram
In 1:2 redundancy mode there is a dedicated BackupUnit (designated as BU) as determined by
the cable position. In this configuration, the BU is responsible for monitoring the two online
units for communications and summary faults.
B–2
HPOD C-, X-, Ku-Band High-Power Outdoor Amplifier
Appendix B
MN/HPOD.IOM
Revision 8
While the BU is constantly monitoring both units for their status, if either has a fault, use the last
(good) status as the configuration for the BU before the BU goes online. Once the BU goes
online, the redundancy auto/manual status reverts to manual mode, and the BU stays online
until reset by the user.
The user may reset the system by issuing a FBU=0 command to place the units back into auto
mode. When issuing this command, the BU then switches back to the “normal” configuration of
SSPAs 1 and 2 online. The system can be operated manually by sending an FBU=1 command
(which forces SSPA 1 to be backed up), or a FBU=2 command (which forces SSPA 2 to be backed
up) to the BU.
In 1:2 applications, the BU also stores an offset value, to be used when the BU replaces an active
unit, for each of the two online units. This offset may be set with the SBO= command. When an
online unit is being “backed up” the BU’s attenuator will be set to this value. This value may be
different than the attenuation value of the online unit to compensate for any gain mismatch
between the BU and online units.
To calibrate, do these steps:
Step
1
Task
After proper operating levels have been established in online SSPA 1 and 2, store their attenuation settings
using the SBO= command in the backup unit.
For example – SSPA 1, the active SSPA, requires 15.00 dB of attenuation. SSPA 2, the BU unit, requires
10.00 dB: Enter the remote commands SBO=1,15.00 and SBO=2,10.00 to store these values.
2
Send the FBU=1 command to the BU unit. This will force the BU unit to replace SSPA 1. The BU unit will
read the setting stored by the SBO=1 command (in this example, 15.00) and apply this value to its own
attenuation setting. This value can now be tuned to compensate for any gain mismatch.
For example – If the output power is 1 dB too high in this state, send ATT=16.00 to the BU unit. If the Tx
level is now correct, send SBO=1,16.00 to the BU unit.
3
Repeat the above process to achieve desired level matching and for SSPA 2.

HPOD Series 1:1 Redundancy Test
B.4.1 Connection
Step
Task
1
Connect HPOD redundancy loop connectors together using a CA/WR12190-1 redundancy loop cable.
2
Connect a 28V waveguide switch to the switch connector on the redundancy loop cable.
3
Since both units will be connected to a single EIA-485 bus, they will need independent serial COMM
addresses.
To simplify the setup:
a.
Power up the unit connected to the “SSPA 2” end of the CA/WR11124-1 cable. Using a EIA-485
connection and a terminal program, set the serial COMM address to “2” (SPA=0002).
b.
Disconnect SSPA 2 from the EIA-485 cable. Connect the EIA-485 cable to and power up the unit
connected to the “SSPA 1” end of the redundancy loop cable. Confirm this unit’s serial COMM
address is “1”. If required set it to “1” (SPA=0001).
c.
When complete, the SSPA connected to the “SSPA 1” end of the redundancy interlink cable
should have EIA-485 COMM address 1 and SSPA 2 will be COMM address 2.
4
Connect both units to the EIA-485 COMM cable and power both units on. Confirm correct serial comms
by sending them both an RET? query and noting the response.
5
The units auto detect the presence of the redundancy loop cable. Send an RED? query to both units.
Both should report RED=1, indicating proper detection of the redundancy loop cable.

Revision 8
B.4.2 Operation
Task
Procedure
1
Set both units to “Auto” redundancy mode by sending them RAM=1 command.
2
Establish the current online status by sending each unit an ONL? query. Note one unit should return
ONL=1 (online), and one unit should return ONL=0 (offline)
3
Fail the unit that reported ONL=1. The switch should throw. Restore the unit
4
Repeat the ONL? query to both units. The unit that was failed in step 2 should now report ONL=0 and the
other should report ONL=1. Fail this unit and confirm the switch transitions.
5
Put the system in “Manual” mode by sending RAM=0 commands to both units.
6
The “SSW” command will force the switch to point to the selected unit. For example, an “SSW=1”
command will force the switch to point to SSPA 1 no matter which SSPA the command was issued to.
Ensure either unit can throw the switch in both directions by sending the following commands:
•
<1/SSW=1 (the switch may or may not transition)
•
<1/SSW=2 (the switch should transition)
•
<1/SSW=1 (the switch should transition)
•
<2/SSW=2 (the switch should transition)
•
<2/SSW=1 (the switch should transition)
