3.3.5 RF power reading and selector switch

The Transmitter Controller has a digital panel meter which displays Forward RF 

Power and Reverse RF Power as detected by the RF power sampler built into the 

output combiner. The reading on the display is determined by the setting of the 

selector switch and accompanying green LED indicator. The readings are in 

Kilowatts and have an accuracy of better that 2% at the specified RF level and 

frequency at the time of order. However, it is recommended that an external watt 

meter be used for a more accurate reading. See illustration 3-5 for the location of the 

panel meter and selector switch with accompanying green LED indicators.
