Description
Sets the reference level offset.
Queries the reference level offset.
Parameter
Name
Type
Range
Default
<rel_ampl>
Consecutive Real Number
-300 dB to 300 dB
0 dB
Remarks
The offset of the reference level only modifies the reference level and amplitude readout of the marker, but
does not change the position of the curve.
Return Format
The query returns the offset of the reference level in scientific notation.
Example
The following command sets the reference level offset to 10 dB.
:DISPlay:WINDow:TRACe:Y:SCALe:RLEVel:OFFSet 10
The following query returns 1.000000e+01.
