ACP AUTO MEASURE turns off the following
functions if they are on:
Trace Math
Video Averaging Functions
Frequency Count
Signal Tracking
AM/FM Demodulation
The spectrum analyzer center frequency should be set
to the transmitter intended center frequency. The
reference level should be set to optimize the displayed
range to minimize the number of data points above the
top or below the bottom of the range of the chosen
display scale. The display scale should be set to LOG 10
dB/division. The input attenuator should be set to
optimize the tradeoff between analyzer-induced
third-order intermodulation distortion products and
noise.
