:LEVel:VOLTs <real number>
:LEVel:VOLTs?
:LEVel:VOLTs?
These commands set/query the expected data signal level (after
de-emphasis, if used). For more information about the effects of
de-emphasis, see the “De-emphasis and Input Level” in the Reference
Guide.

de-emphasis, see the “De-emphasis and Input Level” in the Reference
Guide.
The higher the level of signal expected by the analyzer, the higher the
trigger level is set. The input level should be set high enough to prevent
false triggering, but low enough to allow triggering for valid signals.
This may require you to set the input level well below the expected level.

This may require you to set the input level well below the expected level.
This command requires one of the following settings for the AF
analyzer’s input (AFAN:INP), ‘Audio In’, ‘Audio Out’, ‘Ext Mod’ or ‘SSB
Demod’.
