8 Frequency Scan Measurement

AMPTD Y Scale

PSA had multiple preselectors, but the X-Series has only one. These commands simply alias to

[:SENSe]:POWer[:RF]:PADJust

Initial S/W Revision Prior to A.02.00

Modified at S/W Revision A.03.00

Remote Command

[:SENSe]:POWer[:RF]:PADJust:PRESelector MWAVe | MMWave | EXTernal

[: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

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.

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.

Notes The Y axis unit has either logarithmic or linear characteristics. The set of units that is logarithmic

consists of dBm, dBmV, dBmA, dBµV, dBµA, dBµV/m, dBµA/m, dBpT, and dBG. The set of units that

are linear consists of V, W, and A. The chosen unit will determine how the reference level and all the

amplitude-related outputs like trace data, marker data, etc. read out.
