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.
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 15 dBm (If y-axis is dBm)
Causes the reference level to immediately be set to an automatically computed value that best displays the particular data. The computed reference level is the smallest multiple of the scale that would cause the current trace peak to be positioned half a division from the top grid line. This command is semantically equivalent to :DISPlay[:WINDow]:TRACe[:SCALe]:RLEVel <amplitude> with the computed value for amplitude.
