Reference Level
:DISPlay:WINDow:TRACe:Y[:SCALe]:RLEVel
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.
Syntax: :DISPlay:WINDow:TRACe:Y[:SCALe]:RLEVel <amplitude>
:DISPlay:WINDow:TRACe:Y[:SCALe]:RLEVel?
Cmd Parameter: <amplitude>
Query Response: <amplitude>
Range: With reference level offset = 0 dB: 30 dBm to –130 dBm
Default Value: 10 dBm
Default Unit: Current active amplitude unit
Example: To set the reference level to 15 dBm (If y-axis is dBm)
:DISPlay:WINDow:TRACe:Y:SCALe:RLEVel 15
:DISPlay:WINDow:TRACe:Y:SCALe:RLEVel 15dBm
Related Command: :DISPlay:WINDow:TRACe:Y[:SCALe]:RLEVel:OFFset
