Fields

AF Anl In

The audio frequency analyzer input selects the input for the analyzer. When 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.

AF Cnt Gate

Audio frequency counter gate specifies how long the AF counter samples the signal before displaying the frequency. Specifying a shorter gate time may enable you to see frequency fluctuations that might not be seen using a longer gate time.
