Output Power Adjustment
The RF power output of the amplifier is set to its rated value of 3.0 Watts at the factory. This
should not require adjustment under normal circumstances. However, should it be necessary to
correct the output power, the 'Output Power Adjustment' which is described in the Amplifier
Manual can be adjusted accordingly. If the Synthesizer module is replaced, it is strongly
recommended that the amplifer undergo a realignment as described in the Amplifier Module,
