Download TimePod 5330A Operation and Service

MaskSelect([String mask_name])
This function selects a mask for use with MaskResultMargin() and MaskResultValid(), returning
the previously-selected mask if any. If mask_name is omitted, the function returns the
currently-selected mask name. In both cases, the function will return an empty string if
no mask was selected.
Mask names should be specified exactly as they appear in the masks.txt file accessed via
Masks→Edit mask definitions (which also determines the names under which they are
added to the Masks menu). See MaskResultMargin() for other notes on scripted mask
tests.
MeasurementSelectView(String hotkey)
MeasurementDeferSelectView(String hotkey)
These functions accept a hotkey parameter that consists of the (case-sensitive) shortcut
key for the desired measurement view as it appears in the Measurement menu. For
example, MeasurementSelectView(“P”) will emulate the ‘P’ keyboard shortcut
(Measurement→Phase noise (P)).
If your script is performing mask tests with multiple measurement types, it’s a good idea
to call MeasurementDeferSelectView() as the last action taken before returning from
EventTimer(). Upon the next invocation of EventTimer(), your script should call
MeasurementView() and evaluate the masks or other test parameters for that view,
regardless of any changes to the measurement view that may have taken place between
timer ticks. Script authors are encouraged to use the EventTimer() handler in
5330A_performance_test.js as a model for test procedures that use multiple
measurement types.
The difference between MeasurementSelectView() and MeasurementDeferSelectView() is that
the latter will not take effect until after the event handler returns. This distinction is
important when multiple instances of the same script may be executed at once.
Essentially, deferring the view selection until after all script instances with the same
EventTimer() interval have been serviced leaves a single script instance “in charge” of the
view, reducing opportunities for confusion.
MeasurementView()
Returns the current measurement view as a String containing the hotkey for the view as
it appears in the Measurement menu. For example, when viewing a phase noise plot,
MeasurementView() will return “P”, the shortcut key for Measurement→Phase noise.
See MeasurementSelectView() for additional notes on measurement view selection.
