1.2 Front Panel Indicators

PWR LED The power (PWR) LED shows that the dc supply is connected to the

amplifier.

RFO LED The RF output (RFO) LED indicates that the amplifier is being driven

and there is forward RF power present at the output.

ALARM LED The alarm (ALARM) LED illuminates if the internal temperature rises

above safe limits or high reverse power is present, output power is

automatically reduced in order to protect the amplifier.

1.3 Internal Adjustments

All internal adjustments are factory set and should not need to be changed under normal

conditions. A possible exception to this is the RF output power level which may need

to be changed to comply with local licensing requirements.

WARNING

Ensure that the power setting complies with the

requirements of your licensing authority. Failure to do

so may result in penalties being imposed by the

licensing authority.

Output Power The output power is set by RV1. This is nominally set to 100 Watts

(+50dBm), but may be set to any value between 1 and 120 Watts

depending upon local regulations in the destination country, and the

model of power amplifier.
