General Preferences

The General Preferences tab includes settings that affect the general operation of the 89600 VSA software.

Measurements

Preset measurement on hardware configuration change:

Selected (default): The VSA will return the measurement settings to their preset states each time the hardware configuration changes. This is the default state for backward compatibility.

Cleared: The VSA will try to preserve the measurement settings when possible. In most cases, when switching between hardware configurations:

a) The measurement type is preserved (e.g., if digital demodulation was selected before, it should remain selected)

b) Measurement settings are preserved (e.g., symbol rate)

c) Input extension parameters are preserved

Some hardware configurations may be too dissimilar for this feature to preserve some or all of the measurement settings.

Fast measurement restart:

Selected (default): The VSA will restart the measurement faster than the previous versions of the VSA if the current measurement supports faster measurement restarts. Previously, a measurement restart displayed a blank trace before starting the first data acquisition. If the measurement supports it, this blank trace is not displayed and the first acquisition of data is started immediately.

Cleared: The VSA will retain the behavior of previous versions where a measurement restart causes a blank trace to be displayed before starting the first data acquisition.

If fast measurement restart is not supported by a measurement, then it retains its previous behavior (as if fast measurement restart is cleared). If multiple measurement are restarted at the same time and any of the restarted measurements do not support fast measurement restart, then none of the measurements will do the fast restart.

Preset the custom channel configuration's logical to measurement channel mapping on measurement preset:

Selected: The VSA will retain the behavior of previous versions where the custom channel configuration’s logical channel to measurement mapping will be preset when the measurement is preset.

Cleared (default): When a measurement preset is performed, the custom channel configuration’s channel mapping between logical channels and the measurement will not be preset.

Macros Path

The Browse button opens a dialog for selecting the path where user-created macros are stored. The default macros path is C:\Users\<user>\Documents\Keysight\89600B VSA\Macros.
