Amplitude Unit

This displays the menu keys that enable you to change the amplitude unit for X Axis. For this measurement,
the amplitude level falls on the X-axis of the display.

PSA had multiple preselectors, and you could select which preselector to adjust. Since the X-Series
has only one mm/uW preselector, the preselector selection softkey is no longer available. However,
to provide backward compatibility, we accept the legacy remote commands.
The command form has no effect, the query always returns MWAVe

If an amplitude correction with an Antenna Unit other than None is applied and enabled, and you then
turn off that correction or set Apply Corrections to No, the Amplitude Unit that existed before the
Antenna Unit was applied is restored.
In the EMI Receiver application, this parameter is coupled to the X Axis unit of other measurements.
