Y Axis Unit
Sets the unit of the Y-axis unit to Peak, RMS, or Power.
Remarks:
The Y-axis unit is valid when the data source is "CaptureTime" or
"CaptureSpectrum". After a unit is selected, the instrument will process the
signal data according to the currently selected unit. At this time, you can
observe the changes of the trace in the selected trace window, but the display of
the graticule scale remains unchanged.
For other data sources, if the trace format is "Log Mag", the default unit is dB; if
you select "Wrap Phase" or "Unwrap Phase", the default unit is deg. Other trace
format data are normalized, so they do not have the unit.

Copy Y Scale
Copies the Y scale of the current trace to other traces. The available ranges can be
Trace1 through Trace4.
Note: Only when the X-axis and Y-axis units of different traces are the same, the
Y-axis scale information can be copied between different traces.
