selected, this field displays a list of choices.
Signals can be analyzed from three different types of inputs:
• The output of the AM, FM, or SSB demodulators.
• The AUDIO IN, MODULATION INPUT, MIC/ACC, and AUDIO OUT connectors.
• The signal present at the AM or FM modulators for the RF Generator.
See “AF Analyzer” in the GPIB Command Syntax chapter of the Agilent
Technologies E8285A Condensed Programming Reference Guide for
programming command syntax.

you to see frequency fluctuations that might not be seen using a longer gate time.
