AMPTD Y Scale
interest. This function is only available when “Presel Center” on page 868 is available.
For general purpose signal analysis, using Presel Center is recommended. Centering the filter minimizes
the impact of long-term preselector drift. Presel Adjust can be used instead to manually optimize the
preselector. One application of manual optimization would be to peak the preselector response, which
both optimizes the signal-to-noise ratio and minimizes amplitude variations due to small (short-term)
preselector drifting.
Key Path: AMPTD Y Scale
Scope: Meas Global
Remote Command: [:SENSe]:POWer[:RF]:PADJust <freq>
[:SENSe]:POWer[:RF]:PADJust?
Example: POW:PADJ 100KHz
POW:PADJ?
Notes: The value on the key reads out to 0.1 MHz resolution.
Dependencies: • Grayed out if microwave preselector is off. )
• Grayed out if entirely in Band 0.
• Blank in models that do not include a preselector, such as option 503. If
the SCPI is sent in these instruments, it is accepted without error, and the
query always returns 0.
• Grayed out in the Spectrogram View.
Preset: 0 MHz
State Saved: The
Presel Adjust value set by Presel Center, or by manually adjusting
Presel Adjust, is not saved in instrument state, and does not survive a Preset
or power cycle.
Min: –500 MHz
Max: 500 MHz
Default Unit: Hz
Backwards Compatibility SCPI: [:SENSe]:POWer[:RF]:MW:PADJust
[:SENSe]:POWer[:RF]:MMW:PADJust
PSA had multiple preselectors, but the X-Series has only one. These
commands simply alias to [:SENSe]:POWer[:RF]:PADJust
