:DISPlay:WAVeform[n]:WINDow[m]:TRACe:Y[:SCALe]:RLEVel?
Sets the amplitude reference level for the y-axis.
n, selects the view, the default is RF envelope.
n=1, RF envelope
n=2, I/Q waveform
m, selects the window within the view. The default is 1.
Factory Preset
and *RST: 0 dBm, for RF envelope
Range: −250 to 250 dBm, for RF envelope
Default Unit: dBm, for RF envelope
Remarks: May affect input attenuator setting.
To use this command, the appropriate mode should be
selected with INSTrument:SELect.
