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.

2.2 Connector Pin-Outs
The Mini Compact Outdoor SSPA utilizes a variety of connectors for communication with the
amplifier.
2.2.1 RF In (J1) [Type N (F)]
The RF Input signal is applied to J1, which is a type N female connector. The Mini Compact
Outdoor SSPA has a default maximum nominal gain of 75 dB minimum. Therefore the
maximum input signal required to saturate the amplifier can be calculated as:
Input Power = Psat – 75 dB
For example, if a 50 W Ku-Band Mini Compact Outdoor amplifier is used in a system it has a
Psat = 47.0 dBm. Therefore the maximum input power should be limited to -28 dBm. Slightly
higher input power levels will not damage the amplifier but will result in higher levels of
distortion in the output signal.
WARNING! The maximum input level should be limited to +15 dBm to
avoid damaging the amplifier.
2.2.2 RF Out (J2)
The amplifier’s output is brought out through the waveguide port, J2. Caution should be
observed here to make sure that the antenna or a suitable termination is connected to this
port before operating the amplifier. The amplifier is protected against full reflection but
dangerous levels of microwave energy can be present at this port.
Ku-Band amplifiers have a WR-75 Grooved Flange while the C-Band and X-Band amplifiers
have CPR style grooved flanges (CPR-137G for C-Band; CPR-112G for X-Band). An isolator
is provided at the output flange with a termination capable of handling full reflected output
power.
WARNING! Never look directly into the RF output waveguide.

Operations Manual, HPA3, Mini Compact Outdoor SSPA

2.2.3 RF Output Sample Port (J3) [Type N (F)]
The RF Output Sample port, J3, is located on the bottom of the amplifier as shown in Figure
2-1. This connector provides a -40 dBc coupled sample of the amplifier’s output signal. It is a
type N female connector.
2.2.4 Monitor & Control Port (J4) [MS3112E18-32S]
The M&C (Monitor and Control) connector is the primary input for controlling the amplifier and
monitoring fault conditions. It is a 32-pin circular connector, MS3112E18-32S. It requires a
mating connector, MS3116F18-32P, which is supplied with the unit. The pin-out for this
connector is described in Table 2-2 on the following page.
The Mini Compact Outdoor Amplifier has no on/off switch or circuit breaker in the AC Input
path. As soon as AC power is applied to J7, the unit’s power supplies and microcontroller are
enabled and the cooling fans should begin to spin. However, the internal amplifier module
is disabled until the Mute Line Input (J4, Pin B) is pulled to Ground (J4, Pin V). If it is
desired to have the RF enabled every time the AC input is applied, a permanent connection
can be made between J4, Pin B and J4, Pin V.
2.2.4.1 Alarms on J4
A variety of alarm signals are present at the M&C connector, J4. Both Form-C relays and
open collector outputs are available.
2.2.4.1.1 Summary Alarm (J4) Form C Contacts
The Summary Alarm is accessible in both Form C relay and open collector format. The
Form C relay is “energized” under normal operating conditions and “de-energized”
when a Fault condition exists.
2.2.4.1.2 Auxiliary Alarm (J4) Form C Contacts
The Auxiliary Alarm relay is an end user alarm that can be used to signal an alarm
condition that is dependent on the state of the Auxiliary Input (J4-Pin P).
The Auxiliary Input is a contact closure to ground. When this input is pulled to ground
the Auxiliary Alarm relay is energized (Normal State). When the Auxiliary Input is open
circuited the Auxiliary Alarm relay is de-energized (Alarm State).
2.2.4.1.3 Open Collector Alarm Outputs (J4)
The open collector alarm outputs will require external pull-up resistors (unless
connected to the Auxiliary Input). They are capable of sinking up to 20mA current at 30
VDC. The open collector outputs are pulled to ground under normal operating conditions and switch to high impedance state during an alarm condition.
• Auxiliary Alarm: follows state of Auxiliary Input as described above

Operations Manual, HPA3, Mini Compact Outdoor SSPA

2.2.4.2 Serial I/O Control (J4)
For serial data control of the Compact Outdoor SSPA, a Windows-based Monitor &Control
program is supplied with the amplifier that allows all of the control and alarm functionality over
a serial communication link.
Both RS-232 and RS-485 can be used to communicate with the amplifier. The amplifier
default is to operate on RS-485 but can easily be set to RS-232 by pulling the RS-232/
RS-485 Select line low. This is done by connecting J4-Pin D to J4-Pin V.
The Mini Compact Outdoor Amplifier may be supplied with a Quick Start Cable in which this
connection is already made. This allows the user to quickly setup the amplifier and verify its
operation. The other side of the cable has a 9-Pin female D connector that mates with most
notebook and desktop personal computers.
Communication links using RS-232 are typically good up to 30 ft. (9 m) in length. Installations
exceeding this length can use the RS-485 mode which will allow serial control up to 4000 ft.
(1200 m).
2.2.5 Link Port (J5) [MS3112E10-6S]
The interface connector is used to connect between two Compact Outdoor Amplifiers when
used in a 1:1 redundant system. It is a 6-pin circular connector, MS3112E10-6S. It requires a
mating connector, MS3116F10-6P. A link cable is provided with a 1:1 Redundancy Kit, which
can be purchased separately. See Table 2-3 for a pin-out of this connector.

2.2.9 Chassis Ground Pin
A Chassis ground terminal is provided on the bottom side of the amplifier. A ¼ - 20 threaded
terminal is provided for equipment grounding.

2.3 Physical Features
In addition to the I/O connectors, the Mini Compact Outdoor user-friendly features include a
summary alarm indicator and a removable fan tray.
2.3.1 Summary Alarm Indicator
A summary alarm indicator LED is located on the input side of the amplifier. When the SSPA
is online, this indicator illuminates GREEN. When in a fault condition, it illuminates RED.
2.3.2 Removable Fan Tray
The Mini Compact Outdoor Amplifier’s cooling system represents a landmark in microwave
telecommunication amplifiers. It is a unique system of heatsinks that have been computer
optimized to provide extremely efficient cooling of all of the system’s functional blocks. This
high efficiency cooling system is primarily responsible for the small overall package size and
reduced weight of the unit (approximately 24.5 lbs or 11.1 kg).
The cooling system is based on a forced convection technique in which the system fans
provide the air intake while the exhaust is brought out around the outer perimeter of the fans.
The fans are 132 CFM rated and operate into approximately 0.3 in. H2O back pressure, and
produce 68.0 dB-A measured at a distance of 1 meter from the fan intake.

ETHERNET READY

The air intake and exhaust are both located on the bottom side of the amplifier. The intake is
brought through two fans while the exhaust is along the two rows of heatsink fins as seen in
Figure 2-2.

airflow from exhaust to intake.
Operations Manual, HPA3, Mini Compact Outdoor SSPA

208143 REV -

Warning! The Mini Compact Outdoor SSPA should NEVER be mounted
with the fans facing up. Doing so will void your warranty.
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 6: Troubleshooting and Maintenance for cleaning instructions.

2.4 Installation
The light-weight chassis of the Mini Compact Outdoor SSPA is ideal for mounting the unit—or
redundant assembly—directly to an antenna boom. These instructions outline how to install a
Mini Compact Outdoor SSPA unit onto an antenna boom using a Universal CO mounting Kit.
This kit allows installation of the Mini Compact Outdoor SSPA on antenna booms up to 10”
thick.
2.4.1 Safety Considerations
These instructions are designed to be used by a single operator. As such, several safety
issues should be kept in mind during the installation.
1. The Paradise Datacom Mini Compact Outdoor SSPA base unit weighs approximately 24.5
lbs., and should be handled with care to avoid scratching the exterior coating and compromising the unit’s corrosion resistance;
2. All bolts should be torqued down to within reasonable limits to avoid stripping the threads.
3. The section of antenna boom the unit is to be mounted on should be straight, dry and free
from corrosion or defects.
2.4.2 Inspection
On receiving the Universal CO Mounting Kit, inspect the contents to ensure all parts listed in
Table 2-8 are present.

3.3.1.2 Fault Status Indicators
The Fault Status frame in the lower left side of the Status Window contains a grid of SSPA
fault indicators. See Figure 3-9, Item [2]. A green indicator signifies proper operation; red
signifies a fault condition.
Summary Alarm: The Summary Alarm is simply a logical ‘OR’ of any of the alarm indicators.
Unit Online: The Unit Online indicator is relevant in redundant systems. If the unit is clear of
faults and active, the indicator will be green. If the unit is offline or in standby mode, the
indicator will be red.
External Mute Alarm: The External (Ext) Mute line gives an indication via the M&C screen
that the SSPA has been externally muted by J4-Pin B. This external mute alarm can be
configured to trigger a summary alarm if desired. The 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. See Section 3.3.2.
Forward RF Fault: The Forward RF Fault Alarm is configurable from the Settings Window.
See Section 3.3.2.
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. The
Temperature Alarm is intended to warn the operator of possible fan problems and eventual
amplifier shutdown.
Low DC Current Alarm: The Current Fault is factory preset to alarm if the SSPA module
current falls below 60% of its nominal value.
Low DC Voltage Alarm: The Voltage Alarm is factory preset to alarm if the SSPA module
current falls below 80% of its nominal value.
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.
Fiber Alarm: The Fiber Alarm is configurable from the Settings Window. See Section 3.3.2.
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. These configuration are covered in Section 7, the
Redundant System Concepts description.

3.3.1.3 Voltage, Current and Temperature Display
On the right side of the Status window there is a thermometer display that reports the present
temperature of the amplifier. See Figure 3-9, Item [3]. A 20-30°C rise above ambient
temperature is typical.
To the left of the thermometer display are several indicators that show various operating
conditions of the Compact Outdoor 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 12 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 GaAs transistors. The Gate Voltage indicator
monitors the DC voltage of the gate circuitry of the microwave GaAs 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 to the right
of the Carrier Enable status. See Figure 3-9, Item [4]. 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 by entering the value into the text box, or by clicking on the
up/down buttons.
3.3.1.5 RF Power Indicator
The RF Power indicator is the vertical meter in the central part of the Operation window. See
Figure 3-9, Item [5]. This indicator reports the approximate 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.
3.3.1.6 Reference Source
If the amplifier is equipped with a block up converter, the reference source will be indicated
above the fault status window. See Figure 3-9, Item [6].

The SSPA will use the default settings until the unit is reset 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.
Make sure that the Protocol Select setting in the Settings tab of the Universal
M&C is set to IPNET, as shown in Figure 3-10.
If custom IP settings will be used in normal operation, do not use the Quick Start
cable (207755) that was shipped with the unit. The user will need to construct
an IP cable with connections to J4 as shown in Figure 3-2. In this configuration,
the SSPA will always use the saved communication control settings rather than
the default configuration.

Section 4: L-Band Operation
4.0 Block Up Converter Overview
The Mini Compact Outdoor SSPA is available with various converter options, utilizing
Paradise Datacom’s integrated converter. The primary up converter option is offered in two
C-Band configurations, two Ku-Band options, and one X-Band model. The BUC offers ultra
low phase noise for applications where phase noise is an overriding factor. For specifications,
see Table 4-1.
The type of BUC housed within your Mini Compact Outdoor SSPA is indicated by its model
number, as shown in Figure 4-1. The example listed shows a 100W C-Band Mini Compact
Outdoor SSPA with Internal Reference BUC. For a full description of this configurator, refer to
the Mini Compact Outdoor SSPA specification sheet (208142).

The block up converters are high performance frequency translation devices which
provide excellent phase noise and spurious performance. The 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. See Section 4.4 for more detail.
The converter utilizes 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 reconfiguration.
The schematic of Figure 4-2 shows the electrical position of the block up converter.
It is important to remember the requirement of a reference oscillator when operating an SSPA
with BUC (SSPB). If the 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 Theory of Operation
The low gain block up converter has a P1dB of 0dBm. This topology allows the system to be
integrated with little impact on the general electrical specifications of the SSPA module.
The 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
Paradise Datacom’s converters come standard with smart reference technology. Smart
reference technology allows the system operator to change external system reference
frequency without any system configuration required. The converter will automatically sense
and lock to any one of the following system reference frequencies: 10 and 50 MHz. With the
internal reference option installed the converter will operate with no external reference
applied. In the event the system operator wishes to operate on external reference, the
converter will automatically sense the presence of an external reference and switch to
external reference mode. This setting is configurable in the monitor and control software. See
Section 3.3.2 for details.
External reference is applied to the converter via the L-Band input IFL and is routed to the
frequency synthesizer using the built-in demux circuitry.

Operations Manual, HPA3, Mini Compact Outdoor SSPA

208143 REV -

Notes:
1) The external reference option requires the system operator to provide system
reference to the BUC/SSPB. The system will not lock and will have no output
without external reference applied.
2) Internal reference option allows for either internal or external reference operation.
The 10 MHz crystal reference used in the internal reference of the converter has the following
specifications:

4.4 FSK Monitor and Control
FSK Monitor and control comes standard with the converter. This allows the Mini Compact
Outdoor SSPB to be fully and remotely monitored and controlled through the system’s IFL. An
embedded controller enables remote communication and fault detection via the IF input
between the SSPA and a Paradise Datacom Evolution Series L-Band modem. This signal
consists of a 650 KHz Frequency Shift Keyed carrier that is multiplexed onto the L-Band input
IFL along with the external reference signal. The monitor and control 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:

Section 5: Performance Tests
5.0 Introduction
This section describes some of the tests performed on production amplifiers before shipment.
Where possible, Paradise Datacom LLC maintains computer automated RF test stations to
ensure a high level of accuracy and consistency to production amplifier testing.

5.1 Standard tests
All Paradise Datacom Compact Outdoor amplifiers must meet rigid specifications and
undergo the following tests. Copies of the final test data are shipped along with the unit and/
or system. Figures 5-1 through 5-3 show examples of the final test data for a 140W C-Band
Compact Outdoor amplifier with an integrated block up converter.
5.1.1 Swept Gain
The amplifier gain is swept over the operating frequency range under small signal conditions
to confirm the minimum gain and gain flatness specifications. The entire Compact Outdoor
amplifier is tested in a temperature chamber from -40 °C to +60 °C and the gain is recorded.
See Figure 5-1, Item [1].

Figure 5-1: Spurious and Gain Data
Operations Manual, HPA3, Mini Compact Outdoor SSPA

208143 REV -

5.1.2 Spurious
Spurious signals are undesirable byproducts of amplifiers caused by nonlinearities within the
amplifier and other system level components such as switch mode power supplies. These
unwanted signals cause signal management problems in system applications. Out of band
spurious signals cause interference to other pieces of equipment. See Figure 5-1, Item [2].
5.1.3 Input Return Loss
The input return loss is measured in all production amplifiers. This is a measure of how
closely the amplifier is matched to its characteristic impedance. The input impedance of the
amplifier is a nominal 50Ω. See Figure 5-2, Item [1].
5.1.4 Output Return Loss
The output return loss is measured in all production amplifiers. This is a measure of how
closely the amplifier is matched to its characteristic impedance. The output impedance of the
amplifier is matched to the waveguide complex impedance. See Figure 5-2, Item [2].

Figure 5-2: Return Loss, Intermodulation and Phase Noise Data

208143 REV -

Operations Manual, HPA3, Mini Compact Outdoor SSPA

5.1.5 Intermodulation Distortion
Intermodulation distortion is one of the most important characteristics of a Solid State power
amplifier system. Satellite communication systems must comply to certain distortion levels
depending on the service involved. All production amplifiers are subjected to automated
intermod testing. This is based on a standard two-tone intermod test in which the intermod
level (IMD) is measured in dBc with respect to the main tones and the highest third order
intermod products.
Satcom amplifiers are typically used in some ‘back-off’ condition. This is the operating point at
which the composite output power is ‘backed-off’ from the amplifier’s P1dB, compression point.
A curve of back-off vs. IMD level is especially useful in the selection of a power
amplifier or determining the proper output power setting in a Satcom system.
Paradise Datacom recognizes the importance of this back-off characteristic and provides a
plot of back-off vs. IMD from 1 dB to 10 dB back from the amplifier’s compression point.
Figure 5-2, Item [3], shows a typical back-off curve from a production test set.
5.1.6 Power Requirements
This test measures the power requirements of the unit over the various voltages appropriate
for the unit under test. See Figure 5-3, Item [1].

208143 REV -

5.1.7 Earth Ground
This test measures the leakage current and verifies that each pin on J8 is connected
correctly. See Figure 5-3, Item [1].
5.1.8 Sample Port
The RF Sample Port is measured at discrete frequencies across the band and a calibration
label is placed near the Type N connector on the bottom of the unit. The sample port is
approximately -40 dB from the RF output level. A label with the exact coupling ratio is
attached to the amplifier chassis. See Figure 5-3, Item [2].
5.1.9 P1dB and Psat
The 1dB Gain Compression Point is measured at discrete frequencies across the band to
characterize the output power over the operating frequency range. The P1dB measurement is
a guaranteed minimum specification.
As the input power increases, the output power limits to some maximum level. This is defined
as the saturated output power or Psat. The Psat specification is a typical value and is not
guaranteed. This is due to the variation that exists among microwave power semiconductors.
The saturated output power is typically 0.5 dB to 1.0 dB above the P1dB value. See Figure
5-3, Item [3].
5.1.10 I/O Test
This test verifies that the unit has the correct wiring on the MS connectors by testing faults,
communications, and redundancy. See Figure 5-3, Item [4].
5.1.11 Ethernet
Tests Ethernet communication, web monitor and control, and assigns a MAC address to the
unit.

Operations Manual, HPA3, Mini Compact Outdoor SSPA

5.2 Tests for units with integrated BUC
If the Compact Outdoor amplifier includes a block up converter (BUC), the following tests are
included.
5.2.1 Reference Lock
This test checks the external/internal references (if equipped), as well as lowest locking level
at 10 MHz. See Figure 5-3, Item [5].
5.2.2 FSK
Verifies FSK communication with the BUC. See Figure 5-3, Item [6].
5.2.3 Phase Noise
Tests phase noise using external and internal (if equipped) references. The unit is required to
meet at each decade, as well as fall below the spec line determined by the decades. See
Figure 5-2, Item [4].
5.2.4 Microphonics
A spectrum analyzer is connected to the unit and is set to perform a max hold on the trace, .
The unit is then tested as per our procedure.

5.3 Optional Tests
The following tests are performed on units at the request of the customer, usually to verify
specific customer requirements.
5.3.1 Noise Figure
Using a noise figure meter, the unit is tested to verify it operates within specification.
5.3.2 Group Delay
The testing software measures the linear, parabolic, and ripple components to verify the unit
is within specification.
5.3.3 AM/PM
The testing software measures the slope of the amplifier’s insertion phase vs. output power.
5.3.4 Noise Power
Noise power is the total noise per bandwidth at the output of the unit when a signal is not
present.
5.3.5 Harmonics
The testing software measures the 2nd and 3rd harmonics of the unit (as long as the frequency
range is within the capabilities of the equipment).

Section 6: Maintenance and Troubleshooting
6.0 Introduction
This section describes some of the standard maintenance practices that can be performed on
the Mini Compact Outdoor Amplifier and tips to troubleshoot common customer issues.

6.1 Cooling System Maintenance
It is recommended that the cooling system be checked at least once per month. This involves
visually inspecting the fan intakes to make sure that there is no obstructions over the intake.
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 20°C to 25°C rise
above the current outside ambient temperature. If the base plate temperature exceeds this
temperature rise, it is one indicator that the system’s airflow requires maintenance.
The heatsink fins in the exhaust path can 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 for
easy cleaning.
Failure to keep the fans and heatsink clear of debris will void your warranty.

6.2 Fan Removal and Heatsink Cleaning
It is recommended to remove prime AC power from the amplifier when the fan tray is being
removed. However, if necessary, the fan tray can be removed while the amplifier is operating.
Caution should be used to make sure that no clothing or fingers are caught in the fan blades.
Simply remove the four screws from the fan tray and the fan assembly can be removed from
the bottom of the amplifier assembly.
The fans are connected to their power source by weatherized in-line circular connectors. A
replacement fan with connector can be provided for replacement. While the fan tray is
removed, the heatsink fins can be cleaned by spraying compressed air throughout the finned
area. A can of dust remover spray such as that which is found at a computer or electronics
shop will work fine. All debris should be removed before installing the fan tray.
6.2.1 Fan Replacement
The Mini Compact Outdoor SSPA utilizes a two-fan air intake tray, and any maintenance
requiring replacement of the fans should use fan kit L207853-1. This kit replaces the entire
fan tray assembly.

6.3 Troubleshooting guide
The following section describes solutions for some of the most common issues with the operation of the Mini Compact Outdoor SSPA.
6.3.1 Unit doesn’t power up
Cooling fans do not spin, and alarm LED lamps are off.
Possible causes: AC power is off; Unit 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!
6.3.2 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.
6.3.3 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 2-2). 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.
6.3.4 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.

208143 REV -

Operations Manual, HPA3, Mini Compact Outdoor SSPA

Possible solutions:
a) 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 3.2.2.2). After establishing a
communication link with the unit, adjust the following settings to the desired configuration:
Serial Network address, Communication Interface, Baud rate (if Serial was set in in the
Communication Interface), 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.
b) 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.
c) 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 Table 2-2 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.
d) 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.
e) 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.
f) Binary and Terminal protocols are no longer supported by Compact Outdoor units. Use
the currently available interfaces instead.
6.3.5 The FSK link between a modem and the SSPB unit is not working
Possible cause: The unit is set to use a different address.
Possible solution: Set the SSPB address to 1. Reset AC power.

Section 7: Redundant System Configurations
7.0 Redundant System Concepts
The Mini Compact 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 Mini Compact 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 RCP2-1200 controller is required.

7.1 1:1 Redundant Systems
The three most common forms of 1:1 redundant system are shown in Figures 7-1 through
7-3.
Figure 7-1 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.

RF Output
C Band
or
Ku Band

Figure 7-1: Standard 1:1 Redundant System with input (coaxial) switch
and output (waveguide) switch
With the system configured as in Figure 7-2, 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.

Operations Manual, HPA3, Mini Compact Outdoor SSPA

208143 REV -

The system shown in Figure 7-3 uses the same concept of the power splitter on the RF input.
In this case the Compact 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 7-3: 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 Compact Outdoor Amplifier.

7.2 1:2 Redundant Systems
The Mini Compact Outdoor Amplifier can also be configured in 1:2 Redundant Systems. The
major difference being that the amplifier’s internal controller can not be used for system
control. Instead a separate RCP2-1200 Redundant System controller is used to provide
system control. The controller can be remotely located up to 500 ft. from the amplifiers.
Figure 7-4 shows a 1:2 Compact Outdoor Amplifier Redundant System.

Serial interface can be selected between RS232/RS485, Ethernet 10Base-T or FSK over IFL
input (FSK interface is available only on units with an optional L-Band block up converter).
RS232/485 interface can be used in conjunction with Paradise CO 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.
Note: Binary and Terminal protocols used on previous generation units
are no longer supported.
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!

Operations Manual, HPA3, Mini Compact Outdoor SSPA

208143 REV -

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

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.
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 RS232/RS485 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!

Operations Manual, HPA3, Mini Compact Outdoor SSPA

8.1 Serial communication
This section describes the normal communication protocol between the Mini CO SSPA and a
host computer over RS232/RS485 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 RS232 and RS485 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.

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 or 0xAA (see Section 8.1.5
Multiple Device Access). 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

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 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 8-2.

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 8-3.

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).

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 Mini CO SSPA supports several IP network protocols to provide a full featured remote
M&C interface over an Ethernet LAN:
•
•

IPNet protocol – redirection of standard Paradise Datacom LLC serial protocol over
UDP transport layer protocol. This protocol is fully supported in Paradise Datacom’s
Universal M&C software.
SNMPv1 protocol - protocol intended for integration into large corporate NMS architectures.

In order to utilize either of the protocols listed above, the relevant interface option has to be
turned on. Refer to Sections 8.2.2 IPNet interface and 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:
•
•
•
•

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 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.
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 application
sends a UDP request to SSPA unit and waits for response. The length of time the control
application waits depends on how it is configured. If the timeout is reached and the control
application has not heard back from the agent, it assumes the packet was lost and
retransmits the request. The number of the retransmissions is user configurable.
The Paradise Datacom SSPA Ethernet IP interface can use UDP ports from 0 to 65553 for
sending and receiving. The receiving port needs to be specified through the front panel menu.
For sending, it will use the port from which the UDP request originated. Of course, it is up to
the user to select an appropriate pair of ports that are not conflicting with standard IP services. Paradise Datacom recommends usage of ports 1038 and 1039. These ports are 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 Paradise Datacom protocol frame is shown on
Figure 8-6.
