DISPlay Subsystem

This subsystem provides commands that modify the display of data for the user. They do
not modify the way in which data is returned to the controller.

Scale

:DISPlay:WINDow:TRACe:Y[:SCALe]:PDIVision <rel ampl>
:DISPlay:WINDow:TRACe:Y[:SCALe]:PDIVision?
Sets the scale (dB/division) for the y-axis.

Default Unit:
Front Panel Access: Amplitude, Scale

Reference Level

:DISPlay:WINDow:TRACe:Y[:SCALe]:RLEVel <amplitude>
:DISPlay:WINDow:TRACe:Y[:SCALe]:RLEVel?
Sets the reference level amplitude value for the y-axis.
Note that this may cause a change in attenuation if the automatic input attenuation
coupling is enabled.
