1.3 POWER CALIBRATION
- FWD Power calibration
Disconnect the antenna and connect a wattmeter to the antenna connector. Give power to the amplifier until
you will read on the wattmeter a value corresponding to the equipment nominal power. Then turn the trimmer
A (see mounting plan BOTTOM - PN1071AR2, it is a variable resistor used to adjust the A analog input
measure) until you read approximately the same FWD power value on the display.
- REF Power calibration
Disconnect the antenna and connect a wattmeter to the antenna connector. Connect the Forward power
monitoring cable to the Reflected power input connector. Give power to the amplifier until you will read on the
wattmeter a value corresponding to 10% of the equipment nominal power. Then turn the trimmer B (see
mounting plan BOTTOM - PN1071AR2, it is a variable resistor used to adjust the B analog input measure)
until you read approximately the same REF power value on the display.
- UNB Calibration
Connect a wattmeter before the dummy load. Give power to the amplifier then turn off one slave module: you
will read an amount of unbalancing power on the wattmeter. Turn the trimmer C (see mounting plan BOTTOM
- PN1071AR2, it is a variable resistor used to adjust the C analog input measure) until you read approximately
the same UNB power value on the display.
