The spectrum analyzer, if used, should be configured as follows:
Center Frequency
Span
RBW
VBW
Ref. Level
Attach a ≥ 10 dB, 2 watt or greater, power attenuator to the spectrum analyzer RF input.
The direction control signal characteristics required will depend on the interface option
installed. The direction must be set to the NORMAL state.
R1 = Input Threshold Set
R2 = Output Level Set
R3 = Output Threshold Set

PA Input Alarm Adjustment

Set the signal generator output to RF ON. Adjust the output level of the generator to 10 dB
less than the expected input level. If this level exceeds the range of the input detector, the
detector should be set to its minimum detectable level.
