1. SAFETY
In addition to this section, included by reference are the following pertinent sections of the
International Standard IEC-215, ‘Safety requirements for radio transmitting equipment’:
Appendix D, ‘GUIDANCE ON ASSESSING THE COMPETENCE OF PERSONNEL FOR
DESIGNATION AS SKILLED’ and also Sub-clause 3.1 of the Standard.
Appendix E, ‘GUIDANCE ON SAFETY PRECAUTIONS TO BE OBSERVED BY
PERSONNEL WORKING ON RADIO TRANSMITTING EQUIPMENT’, also Sub-clauses 3.2,
3.7 and 22.1 of the Standard.
To prevent the risk of personal injury or loss related to equipment malfunction Advantech uses
the following symbols for safety related information. For your own safety, please read the
information carefully BEFORE operating the equipment.
Symbols used in manual:
WARNING: This indicates a hazardous procedure that could result in serious injury or death if
not performed properly.
CAUTION: This indicates a hazardous and dangerous procedure that could result in lightto-severe injury or loss related to equipment malfunction, if proper precautions
are not taken.

ARMA-C250-CRM
----------------------------------------------- WARNING ----------------------------------------------------When supplying power to this equipment, use the 3-pin connector provided, to connect to a
grounded power outlet. If power is supplied without grounding to the equipment, there is a risk
of receiving a severe or fatal electric shock.
In the context of this document any voltage that is lethal is viewed as ‘High Voltage’. Therefore,
even prime power (90 to 265V AC) is dangerous because prime power potentials have been
known to cause death or injury.
----------------------------------------------- WARNING ---------------------------------------------------This equipment can not be repaired by the operator. DO NOT attempt to remove the
equipment cover or to disassemble internal components. Only qualified service technicians
should service this equipment. There are high-voltage parts in this equipment presenting a risk of
severe injury to untrained personnel. In addition, there is a risk of damage to precision
components.
----------------------------------------------- WARNING ---------------------------------------------------ALWAYS TERMINATE THE OUTPUT WAVEGUIDE OF THE AMPLIFIER WITH AN
RF LOAD CAPABLE OF DISSIPATING FULL CW RF POWER. SIMILARLY
TERMINATE THE INPUT TO AVOID THE POSSIBILITY OF THE AMPLIFIER
BEING DRIVEN BY STRAY LEAKAGE SIGNALS. Incorporate the termination prior to
applying prime power to the amplifier. This procedure prevents self-oscillation and irradiation of
the local environment. Even if a source is not connected to the amplifier you are working with,
there are situations where the amplifier can go into a self-induced mode and generate high levels
of RF energy. Destruction caused under excessive load voltage standing wave ratio (VSWR) will
void the warranty. Although the equipment has internal protection for VSWR higher than 3:1
and will automatically go in shutdown (with a delay of 1 second), still it is a safe procedure to
avoid unwanted effects.
7
ARMA-C250-CRM
----------------------------------------------- WARNING ---------------------------------------------------DO NOT LOOK INTO THE OUTPUT PORT OF THE POWERED RF AMPLIFIER.
Treat the powered amplifier with extreme care. Keep in mind that levels of microwave radiation
that do not induce immediate physical discomfort in most individuals can be sufficiently high to
induce longer term effects. Your eyes are particularly vulnerable parts of your body.
The permissible levels of exposure are quite low compared to the power levels of the amplifiers
built by Advantech (e.g. less than 10 milliWatt vs 20 to 500 Watt delivered by various units).
The permissible levels are currently being studied by a number of organizations. In the past the
U.S. safety Code established a dosage rate of 10 mW/cm2. Currently there is consideration being
given to reducing the permissible level to 1 mW/cm2 in the United States, as has been the case
for several European countries.
----------------------------------------------- CAUTION----------------------------------------------------THESE ARE HEAVY UNITS. USE TWO OR MORE PEOPLE TO LIFT AND MOVE
this equipment or use an equipment cart. There is a risk of back injury, if this equipment is lifted
by one person.

2. GENERAL INFORMATION
2.1 INTRODUCTION
This manual contains information required to install and operate the Redundant 250 W, C-Band
Rack-mount Solid State Power Amplifier Model # ARMA-C250-CRM, in a 1:1 redundant
configuration.
2.2 DESCRIPTION
The ARMA-C250-CRM includes two 250 W solid state power amplifiers (SSPA) and a
waveguide switching unit for 1:1 redundant operation. Each SSPA incorporates a DC main
power supply and a forced air cooling system. Each SSPA features an RS-485 interface that
provides full remote monitor and control of selected functions. A product outline drawing of a
redundant system is shown in Figure 1 at page 12 & Figure 2 at page 13. The functional block
diagram of a single solid state power amplifier is shown in Figure 3 at page 14 and a functional
block diagram of the redundant system is shown in Figure 4 at page 15.
2.2.1 POWER SUPPLY
The main power supply provides a DC high current output to the HPA (High Power Amplifier),
a low current output to the secondary power supply and to two filtered, low current supplies for
operation of the four fans. The secondary power supply has multiple outputs for operation of the
Monitor and Control Assembly and the front panel display. The main power supply is configured
for operation from 220V AC. The fans are configured for 48V DC.
2.2.2 HPA ASSEMBLY
The HPA Assembly amplifies the RF input signal to a level sufficient for transmission. Integral
to this module are low noise and power amplifier sections as well as variable attenuation sections
that are used for temperature compensation and gain control. Other functionality includes
internal power conditioning, temperature monitoring & high temperature shutdown.
2.2.3 MONITOR AND CONTROL ASSEMBLY
The MCA (Monitor and Control Assembly) monitors all the important operating parameters of
the system, and communicates externally via serial and discrete interfaces as well as the front
panel controls and display.

ARMA-C250-CRM
Notes:
1. All outputs are open-collector NPN transistors that either are turned on (active closed) or are
turned-off (active open). These NPN transistors have the following characteristics:
Vce max. = 24V DC
Vce, sat = 0.8V DC @ Ic = 50 mA
Iceo = 100 µA @ Vce = 12V DC
Maximum sinking current = 50 mA
2. All inputs are one terminal of a voltage comparator with internal protection resistor and
diodes. These inputs are pulled up to the internal +12V DC and have these characteristics:
Maximum input voltage < 24V DC
Open state, input resistance > 50 kΩ
Close state, input source impedance < 1 kΩ
Close state, required sink current < 1 mA
The input is active in close state when it is connected to circuit common J3-15 through a
conducted transistor or contact closure of a relay.
For momentarily-closed input, the input pulse width must be more than 10 ms minimum. The
longer pulse width will allow the attenuation to change by more than 0.1 dB.
3. Remote operation: Once the remote control mode is selected from the front panel of a rackmount amplifier, two remote control interfaces are available for operation: discrete interface
J3 and serial interface J2. At anytime during the operation only one remote control interface
is active (i.e. ready to accept input command) and the control of redundant switch is ignored
if the optional redundant switch software is not installed.
The selection of remote control interface is via the discrete input J3-9. The active-open input
at J3-9 will enable the commands from the serial interface to be acknowledged and carried
out and the active-closed input (i.e. grounding) will enable the discrete remote. The
monitoring outputs are always active (valid) at either remote interface.
4. * = Pins 12, 13, 16, 17, 18 and 19 are active for Redundant option only.

3. INSTALLATION
3.1 INSTALLATION CONSIDERATIONS
1. It is recommended that the redundant system should be installed in a rack cabinet.
2. Regardless of the installation position, ensure that there is a clearance of at least 12 inches
(30 cm) between the air intakes (front of the unit), air exhaust (back of the unit) and any
surface which may obstruct air flow.
3. As the redundant system of SSPAs is connected to an output waveguide system, the rackmount cabinet system has to be fixed to the floor (bolted to a concrete floor or to a structural
member in the floor). The cabinet has holes in the lower corners for 3/8” or ½” bolts. An
optional stability plate may be used; the stability plate is bolted to the floor, then the cabinet
is bolted to the stability plate.
4. To maintain the full EMI and EMC integrity of this equipment, the ground bar of the cabinet
must be bonded to an Integrated Ground Plane or an Isolated Ground Plane Network. The
purpose of this is to mitigate the damaging effects to equipment from Electrostatic Discharge
and Lightning. Except for the AC power supply modules, all the equipment in the rackmount system relies on the rack itself for grounding. Therefore, the ground bar of the rack
must be properly connected to protective earth before operating the system.
3.2 INSTALLATION PROCEDURE
Note that each amplifier is assigned either an ‘A’ or ‘B’ designation based on its mounting
position on the rack
1. Install the first unit (B) on a rack in lower (bottom) position, with the waveguide output
facing the rear.
2. Install the second unit (A) on the same rack in the upper (top) position, just above the first
unit.
3. Assemble the waveguide switch assembly to the RF output of each amplifier using eight
#10-32x1/2” screws and eight #10 lock washers per SSPA. Finger tight all screws.
4. Connect the output of the waveguide switch using eight #10-32 x 1/2” screws, and eight #10
lock washers to the waveguide leading of the antenna.
5. Connect the RF input splitter’s outputs to RF input of each of SSPA (semi-rigid cables are
provided)
6. Connect the connector labeled ‘TOP’ of the Redundant Interface cable to the redundant
interface connector (J6) of amplifier ‘A’ (top amplifier). Similarly, connect the connector
labeled ‘BOTTOM’ of the Redundant Interface cable to redundant interface connector (J6) of
amplifier ‘B’ (bottom amplifier).
7. Tighten all the screws around the RF output of SSPA ‘A’ using a ‘star’ pattern in order to
achieve uniform contact across the entire surface of the flange. Repeat with SSPA ‘B’.
23
ARMA-C250-CRM
8. Repeat step 7 to tighten all screws a second time
9. Connect the RF input source to the input of the RF input splitter, see See Figure 1 at page 12
& Figure 2 at page 13.
10. Connect the AC power source to the AC connector (J5) of each amplifier. Refer to Figure 5
at page 22.
11. Connect the Discrete Interface (J3) of each amplifier to the remote discrete operations control
panel. Refer to TABLE 9 at page 19 for pin assignments and Figure 11 at page 35 for a
schematic of a suggested circuit for a suitable remote control panel. If this interface is not
intended to be used, connect pins 8 and 15 on the mating connector provided for (J3) of each
unit.
12. Connect the Serial Interface (J2) of each amplifier to the serial RS232 port of a PC, using a
split serial cable and an RS485/RS232 adapter. Refer to TABLE 8 at page 18 for pin
assignments and TABLE 13 at page 28 for information regarding the connection to the
adapter.
13. Proceed to Section 5 at page 36, for configuration and operation instructions.
NOTE: The rotating speed of cooling fans is temperature dependent.

4. OPERATION
4.1 INTRODUCTION
The amplifier may be operated via the RS-485 serial interface, discrete interface or the front
panel controls and display. Each method provides full access to the unit’s functions including
system monitoring of all key operating parameters, control of output attenuation and amplifier’s
operational status.
In LOCAL mode, with the aid of the keypad and the LCD display, the operator can navigate
through a series of menus on the front panel which allow the setting of key parameters and digital
display of critical performance indicators. A series of LED indicators provides a summary of the
operational status of the amplifier, see TABLE 11 at page 22 & TABLE 12 at page 22. In
REMOTE mode, using the software supplied with this product or a similar communications
software, the same monitor and control functions can be accessed via the RS-485 interface, see
Section 5.4 Select Local Control Mode at page 37 for more information.
4.2 FRONT PANEL CONTROLS
Per TABLE 5 at page 17, six keys on the front panel provide access to the various display
functions and allow local control of the amplifier. The display functions via a menu system which
provides quick access to all available monitor and control features.
Generally, the [
] and [
] keys are the primary means by which the operator moves between
different displays and menu options. The [Enter] key is used to select a menu item and to confirm
changes made to operating parameters. The [Clear] key is used to reset the FAULT status on an
amplifier once the condition that caused the fault has been corrected. For specific instructions on
the functionality of each sub-menu refer to the appropriate section of this manual.

ARMA-C250-CRM
5.10 RF INPUT AND OUTPUT MONITOR PORTS
The input and output monitor ports on the front panel provide a means to measure input and
output signals (in dBm) using appropriate test equipment. The coupling loss normally associated
with RF sample, must be added to the power level measured at the sample port in order to obtain
the proper value for input or output power level.
The coupling loss may vary with frequency and the specific characteristics of the RF circuit.
Accordingly, a calibration chart is provided via the front panel display for each sample port. The
calibration chart for the port identifies the coupling loss at a number of frequencies across the
operating range of the amplifier. The loss associated with intermediate frequencies can be
obtained by interpolation.
5.10.1
MONITOR CALIBRATION CHART
1. To view the monitor calibration chart for the RF sample port on an amplifier, use the [
] and
[
] keys on the front panel of the amplifier to access the Monitor Calibration sub-menu.
STATUS: ____
MONITOR CALIBRATION
2. Press [Enter] once to view the Output Monitor calibration chart. The display is capable of
showing one line of the calibration chart at a time. Use the [
] and [
] keys to scan the

STATUS: ____
MONITOR CALIBRATION
3. Example: IF CALFACT for output monitor at 6.150 GHz = 40.2 dB, External Power Meter
measurement shows
Pm = +6.8 dBm, SSPA output power will be calculated as follow:
Pout = Pm + |C| = 6.8 dBm + 40.2 dB = 47 dBm.
41
ARMA-C250-CRM
6. ALARMS AND FAULTS
The amplifier monitors all key operating parameters and provides alarm and fault signals both on
the front panel and remotely. Two LED indicators on the amplifier identify ALARM or FAULT
conditions respectively. Also during a fault condition, a display similar to the following will
appear on the front panel:
HIST.FAULT: (message)
<CLEAR> to clear
An ALARM signals that a fault has been detected that may reduce amplifier’s performance or, if
allowed to continue uncorrected, may lead to a FAULT condition, see TABLE 11 at page 22 &
TABLE 12 at page 22. An ALARM will not cause automatic amplifier shutdown. A FAULT
condition occurs when a fault has been detected which has caused, or is likely to cause an
amplifier failure. As such, a FAULT may cause automatic amplifier shutdown depending on the
nature of the fault.
6.1 THERMAL ALARMS AND FAULTS
The amplifier continually monitors internal temperature and current consumption and includes an
automatic shutdown feature to prevent operation at excessive temperatures.
An alarm will be triggered when the internal temperature of the amplifier exceeds 70°C. Amplifier
will continue to operate in this condition. When the base plate temperature exceeds 80°C or current
consumption exceeds a threshold value, a fault will be triggered and the amplifier will shutdown.
The amplifier will automatically restart when its internal temperature cools to 65°C. If a fault has
been caused by any other condition, then the status of the SSPA must be reset (i.e. to NO FAULT)
and the source of the problem should be corrected before the unit can resume operation (see
RESETTING THE SSPA below).
A thermal alarm can be caused by any of the following conditions:
• high ambient temperature (the unit is designed to operate between 0°C and +50°C ambient)
• blockage at air intake or exhaust
• cooling fan failure
6.2 RESETTING THE SSPA
After a fault condition has been detected on the amplifier and the source of the problem
remedied, the fault must be cleared in order for the unit to resume operation. Similarly,
unforeseen circumstances might require default parameters to be reset. Thermal alarm will be
cleared after temperature drops below 65°C.
6.2.1 USING THE SERIAL INTERFACE
From Screen (menu) #1, use the function key ‘F9’ to select the desired SSPA, then press ‘F5’ to
reset the unit.

mounting screws. Replace all connectors to the board exactly in the same place and the same
position as they were on the old one.
CAUTION: Always wear a grounding wrist-strap when working with the Monitor and
Controller Board.
7.10.5.2 Software Considerations
The M & C Board that you are replacing contains specifically calibration data for your unit. In
order to load this data in the memory of the new controller, this data file should be loaded in
“PageB” of the controller memory. The calibration data files for each unit may be found on the
diskette received with this system. The name of the files are Axxxx.hex (for power table files)
and CURAxxxx.hex (for current calibration), where Axxxx is the serial number of the unit. The
Axxxx.hex file must be downloaded first and the CURAxxxx.hex subsequently.
In order to load this data file in the controller memory, follow the procedure in Section 4.3.2 at
page 29: go in Menu Page #3 (by pressing twice on function key F10) and the press function key
F9 (pageB) in order to load in page B of the memory. At the prompt type the name of the file you
want to load.
The unit should be in REMOTE in order to accomplish the data loading. See Section 5.4 at page
37.
Remember to check if the serial address of the unit with the new controller is identical with the
initial address of the unit. If it is different, use the procedure in Section 4.3.2 at page 29 (using
function key F7 in Menu Page #3 to change the address).
CAUTION: An inadequate command by pressing F8 (for Page A) instead of F9 (for page
B) will completely disable the Monitor and Control Board.

screws that are holding it in place). When this grill is removed, access to the two fans permits
their removal (by unscrewing the three screws that hold in place each fan). The left fan has to be
removed first in order to allow the removal of the right one. After freeing the fans, remove the
tie-wraps that are holding the cables of the fans and disconnect them from the connectors that are
leading to the power supply. Use for replacement DC fans (P/N 290-100600-001). Reconnect the
new fans and use a new tie-wrap to tie the cables. Put back in place the fans (using three screws
for each one, and then put back in place the front panel grill (using the 8 screws that are holding
it in place).
To replace the back fans, remove the back panel grill to access the fans (by unscrewing the 8
screws that are holding it in place). When the back panel grill is removed, access to the two fans
permits their removal (by unscrewing the three screws that hold in place each fan). The right fan
has to be removed first in order to allow the removal of the left one. After freeing the fans,
remove the tie-wraps that are holding the cables of the fans and disconnect them from the
connectors that are leading to the power supply. Use for replacement DC fans (P/N 290-100600001). Reconnect the new fans and use a new tie-wrap to tie the cables. Put back in place the fans
(using three screws for each one, and then put back in place the back panel grill (using the 8
screws that are holding it in place).
