DISPlay[:WINDow<n>]:TRACe<t>:Y[:SCALe]:RLEVel:OFFSet <Value>
This command specifies the external attenuation/gain applied to measurements. The
value corresponds to the reference level offset in the spectrum analyzer mode.
Suffix:

Parameters:
<Level> <numeric value> in dB
*RST: 0 dB
Example:
DISP:TRAC:Y:RLEV:OFFS 10
External attenuation (level offset) of the analyzer is 10 dB.
DISP:TRAC:Y:RLEV:OFFS -10
External attenuation of the analyzer is -10 dB. i.e. a gain of 10
dB.
Mode: WLAN
5.8 FETCh Subsystem (WLAN)
The FETCh subsystem contains commands for reading out results of complex mea-
surement tasks. This subsystem is closely linked to the CONFigure and SENSe sub-
systems.
