Agilent Technologies E6380-90073 manual LEVelVOLTs real number LEVelVOLTs?, Mode string MODE?

GPIB Command Dictionary

DECoder subsystem

:LEVel:VOLTs <real number> :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.

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 command requires one of the following settings for the AF analyzer’s input (AFAN:INP), ‘Audio In’, ‘Audio Out’, ‘Ext Mod’ or ‘SSB Demod’.

This command utilizes the “Real Number Setting Syntax” on page 299, but does not use the :STATe command.

DEC:LEV:VOLT?

Screen/field equivalent
