This function automatically selects the reference level in rectangular coordinates. After selection, the trace of the measured value shifts vertically so that the reference level crosses the trace in the middle. The scale division is unaffected. The function can be applied to the active trace or to all traces of the active channel.
To automatically select the reference level of the active trace, use the following softkeys: Scale > Auto Ref Value |
To automatically select the reference level of all traces of the active channel, use the following softkeys: Scale > Auto Ref Value All |
