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,
