Analog Demod Tune And Listen - Keysight x-series User Reference Manual

Analog Demod Tune and Listen

The Analog Demod Tune and Listen key opens the Analog Demod menu that contains keys to turn the
demod function on and off and select modulation type.
When the function is on (set to AM, FM, or ΦM), the demodulated signal is fed to the analyzer's speaker.
Muting and volume control functions are done through the standard Windows speaker volume control
interface.

Tune & Listen is only for Meters, which means that there will be no tune & Listen if any of the scan
sequences are running. When Tune & Listen is turned on, only Meter 1 will return the valid
measurement result. Meter 2 & 3 will return –1000dBm. Meter 2 & 3 will return valid measurement
results when Turn & Listen is turned off.
This key is grayed out when a scan sequence is running. If the grayed out key is pressed, an advisory
message is generated. If the equivalent SCPI command is sent, this same message is generated as
part of a "–221, Settings conflict" warning.

This command above is included for ESU compatibility. The suffix 1|2 is irrelevant to the
