STEP 6 Restore transmitter to normal operating condition and reset the
exciter output power to 100 mW.
STEP 7 End of procedure.
5.8.5.2 Cabinet Reject Load Thresholds
Cabinet reject loads should be set to approximately 3V thresholds at 100% reject power
levels.
5.8.5.3 System Reflected Thresholds
System reflected threshold voltage should be set to approximately 100 mV less than the
detector voltage level noted in "5.8.2.1 Calibrate Reflected Total Power" on page 5-19.
Approximately 2.4V is typical. For a 6kW digital transmitter this corresponds to a
reflected power level of 168W.
5.8.5.4 System Foldback Power
System foldback power (Watts) can be set as needed to a maximum value of 2.8% of
nominal output power.
5.8.5.5 FWD Pwr Warn
Sets kW level where power bar turns yellow.
5.8.5.6 Fwd Pwr Flt
Sets kW level where power bar turns red and fault is entered into log.
