CALIBRATE EXCITER FWD POWER METER

On the Exciter, navigate to the CAL setting under the AD3 Advanced submenu
and select CAL then press OK to calibrate the FWD PWR meter on the Exciter
front panel to ~ 100%.

Please note that the Exciter FWD PWR meter reading is based on the RF_IN_A
BNC feedback sample on the rear panel of the Exciter and is only available when
this sample is connected and in the proper signal level range (35% < FSSI A <
75%).
