AMPTD Y Scale
Y Axis Unit
Displays the menu keys that enable you to change the vertical (Y) axis amplitude unit. The analyzer
retains the entered Y Axis Unit separately for both Log and Lin amplitude scale types. For example, if
Scale Type has been set to Log, and you set Y Axis Unit to dBm, pressing Scale Type (Log) sets the Y
Axis Unit to dBm. If Scale Type has been set to Lin and you set Y Axis Unit to V, pressing Scale Type
(Lin) sets the Y Axis Unit to V. Pressing Scale Type (Log) again sets the Y axis unit back to dBm.
NOTE The units of current (A, dBmA, dBuA) are calculated based on 50 ohms input
impedance.
All four of the EMI units (dBμA/m, dBμV/m, dBG, dBpT) are treated by the
instrument exactly as though they were dBuV. The user must load an appropriate
correction factor using Amplitude Corrections for accurate and meaningful results.
If a SCPI command is sent to the analyzer that uses one of the EMI units as a
terminator, the analyzer treats it as though DBUV had been sent as the terminator.
Remote Command: [:SENSe]:POWer[:RF]:PADJust:PRESelector

[:SENSe]:POWer[:RF]:PADJust:PRESelector?
Notes: 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
