Hello,
I have the following for sale:
------------------------------
AN/PRM-34 Portable Tester for AN/PRC-8, 9, 10, 25, 77, 68, 126 & AN//VRC-12
Military Radios. This is a portable tester that checks for receiver
sensitivity, frequency and transmitter RF power.
The mode switch has the following positions:
* OFF CHK - PTT shows Built In Test results as 01.000 in display for
all pass.
* SENS SQ - to test receiver squelch action.
* FREQ - to measure the transmitter output frequency (or deviation from
channel center).
* FWD PWR - to measure the transmitter output power in Watts ( 1 to 50 Watt
range).
* REV PWR - to measure the reverse power, or VSWR of the antenna.
* FLD STR - to check the output of a radio transmitter and is used to align
the PRC-68 ANT coupler circuit.
* PUSH TO TEST - activate the selected test mode.
* It also has an antenna for field strength measurements so that it could
also be used for a number of different radios including the PRC-68.
* There are BNC connectors for ANT and RADIO.
Theory of Operation
There is a comb generator with outputs of 30, 35, 40, 45, 50, 55, 60, 65,
70, 75, and 80 MHz at -97 dBm with a 900 Hz FM modulation for receiver testing.
There is a Watt meter with a 1 to 50 Watt range along with a digital
frequency counter for transmitter testing and a reverse power test for
antenna VSWR testing.
There is a field strength meter to align the L1 ANT adjustment on the PRC-68
in transmit mode.
