:DISPlay Subsystem
This subsystem provides commands that modify the display of data for the user. They do not modify the way in which data are returned to the controller.
:DISPlay:WINDow:TRACe:Y:ADJust
Title
Adjust Range
Description
Automatically adjusts reference level if input signal strength is too high (ADC error) or too low.
Example
:DISPlay:WINDow:TRACe:Y:ADJust
Front Panel Access
Amplitude, Auto Ref Level
:DISPlay:WINDow:TRACe:Y[:SCALe]:PDIVision <rel ampl>
:DISPlay:WINDow:TRACe:Y[:SCALe]:PDIVision?
Title
Scale
Description
Sets the scale (dB/division) for the y‑axis.
Parameter
<rel ampl>
Default Value
10 dB/div
Default Unit
dB
Range
1 dB to 15 dB

Amplitude, Scale
:DISPlay:WINDow:TRACe:Y[:SCALe]:RLEVel <amplitude>
:DISPlay:WINDow:TRACe:Y[:SCALe]:RLEVel?
Title
Reference Level
Description
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.
Parameter
<amplitude>
Default Value
10 dBm
Default Unit
Current active amplitude unit
Range
With reference level offset = 0 dB: 30 dBm to –150 dBm
Example
To set the reference level to 15dBm (If y‑axis is dBm)
:DISPlay:WINDow:TRACe:Y:SCALe:RLEVel 15
:DISPlay:WINDow:TRACe:Y:SCALe:RLEVel 15dBm

Title
Reference Level Offset
Description
Sets the reference level offset value for the y‑axis.
Parameter
<rel ampl>
Default Value
