Field Descriptions
AC Level
This measurement displays either rms potential (voltage) or audio power (Watts
or dBm).
Operating Considerations
When the unit-of-measure is changed to measure AF power, the external load
resistance must be specified. Refer to the
Ext Load R field description, on page 106.
The input for the ac level measurement on this screen is always the AUDIO IN
connectors.

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, RADIO INTERFACE, MODULATION INPUT, MIC/ACC, and
AUDIO OUT connectors.
• The signal present at the AM or FM modulators for the RF Generator.
