The permissible levels of exposure are quite low compared to the power levels of the amplifiers built by Advantech (e.g. less than 10 mW versus 20 to 500 W delivered by various units). The permissible levels are currently being studied by a number of organizations. In the past the U.S.
This manual contains information that describes installation, operation, and maintenance procedures for the 60W C-Band rack-mount (indoor) Solid State Power Amplifier model ARMA-C60-CRM. Because specialized training is required for some phases of installation and operation, certain parts of this manual are directed only to trained personnel. Warnings appear at the appropriate points to caution all users of potential RF and high-voltage hazards.
ARMA-C60-CRM 3.2 SPECIFICATIONS The SSPA specified herein is capable of meeting or exceeding the performance specifications listed in the following table over frequency range, operating temperature and line voltage variation, unless otherwise specified. The SSPA will meet all RF performance specifications within thirty minutes of application of prime power.
4. MAJOR SUBSYSTEMS AND THEIR FUNCTIONS 4.1 DESCRIPTION The ARMA-C60-CRM is a 60 watt C-Band (5.850 – 6.450 GHz) Solid State Power Amplifier (SSPA).

ARMA-C60-CRM 5. UNPACKING AND INSTALLATION 5.1 INSTALLATION CONSIDERATIONS 1. It is recommended that the amplifier should be installed in a rack. 2. Regardless of the installation position, ensure that there is a clearance of at least 12 inches (30 cm) between the air intake/exhaust (back of the unit) and any surface which may obstruct the air-flow.
ARMA-C60-CRM 6. OPERATION 6.1 INTRODUCTION The amplifier may be operated via the RS-485 serial interface, discrete interface or from the front panel controls and display. All methods provide full access to the unit functions including system monitoring of all key operating parameters, control of output power and of amplifier operational status.

ARMA-C60-CRM 6.4 DISCRETE INTERFACE The discrete interface provides all the necessary functions to monitor and control the amplifier. The unit provides open collectors for continuous monitoring alarms, faults, amplifier status and amplifier enable/disable switching. Figure 9 at page 31 provides the detailed circuit information required to use the above features.
ARMA-C60-CRM 7. CONFIGURATION AND SET-UP 7.1 SOFTWARE CONFIGURATION The program ADV.EXE is located on the diskette delivered with this amplifier. To use the software, first copy ADV.EXE to your hard disk. 1. To execute the program, at the DOS prompt type ADV.
ARMA-C60-CRM 7.3 START-UP 1. Switch the power on (Front Panel). The POWER ON LED (green) will light and a message will appear on the front panel display indicating that the unit is performing self-diagnostics. If everything is OK, a second message will appear identifying the model number of the unit.
ARMA-C60-CRM 1. From the main menu, press either [ ] or [ ] successively to select the following display: STATUS: ____ <ENTER> FOR LOCAL CTL STATUS: ____ <ENTER> TO GO REMOTE 2. Press [Enter] to switch between the two modes. When switching to LOCAL control, the unit will wait 30 seconds before yielding local access.
ARMA-C60-CRM 7.6 GAIN ADJUSTMENT The output attenuation of the amplifier will be set to the factory default setting of 10 dB, or the previous setting stored in memory. (2 minutes wait period) 7.6.1 F ROM THE RONT ANEL 1. Verify that the unit is in LOCAL control mode (REMOTE/LOCAL LED indicator is OFF).
ARMA-C60-CRM 7.7.2 U SING THE ERIAL NTERFACE 1. Verify that the unit is in REMOTE control mode (REMOTE/LOCAL LED indicator is ON). If not, switch to REMOTE mode as instructed in Section 7.4 Select Local Control Mode at page 33.
ARMA-C60-CRM 7.8 STATUS DISPLAY SCREENS The front panel display allows an operator to view information on a number of critical operating parameters. Use [ ] and [ ] keys to move between the various displays and sub-menus. The following are typical status displays.
ARMA-C60-CRM 7.10 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.
ARMA-C60-CRM 8. 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 and FAULT conditions respectively. Also during a fault condition, a display similar to the following will appear on the front panel: HIST.FAULT: (message)
