AcqClearParams()
Each script instance maintains a dictionary of acquisition parameters that can be used to
override any or all of the acquisition dialog parameters when
AcqStartAcquisition()
is called.
AcqClearParams()
clears this dictionary. It is normally called before issuing the
AcqSetParam()
call(s) needed to configure the measurement.
Acquisition parameters that the script does not explicitly set with
AcqSetParam()
will
assume their default values when the measurement begins.
See
AcqNumParam()
,
AcqStrParam()
and
AcqSetParam()
for more information.
AcqGetAMSpurTable(Array offset_array, Array amplitude_array)
Populates
offset_array
and
amplitude_array
with a list of all detected AM spurs in the
current measurement, returning the total number of AM spurs.
AcqGetPMSpurTable(Array offset_array, Array amplitude_array)
Populates
offset_array
and
amplitude_array
with a list of all detected PM spurs in the
current measurement, returning the total number of PM spurs.
AcqGetXDEVBins(String selection, Array tau_array, Array sigma_array)
AcqGetXDEVChart(Array tau_array, Array sigma_array)
Populates
tau_array
and
sigma_array
with a list of sigma(tau) values from all valid bins in
the specified statistical measurement, or from the most recently rendered sigma(tau)
chart, depending on which function is called. The selection parameter passed to
AcqGetXDEVBins()
should be a string beginning with ‘a’, ‘h’, ‘m’, or ‘t’, corresponding to
Allan deviation, Hadamard deviation, modified Allan deviation, or time deviation,
respectively.
The
AcqGetXDEVBins()
function differs from
AcqGetXDEVChart()
in that
AcqGetXDEVChart()
returns results only for the 1, 3, 10 tau multiples beginning at t=1s that were displayed
in the most-recently-visible numeric table for the measurement. Before calling
AcqGetXDEVChart()
, you should use
MeasurementSelectView()
or
MeasurementDeferSelectView()
to
display the statistical measurement for which the chart contents should be returned.
Additionally,
TraceShowNumTab(true)
should be called to ensure that the numeric table is
visible, and the script must allow time for at least one frame to be rendered.
AcqGetXDEVBins()
does not have any of these constraints.
AcqNumAcquiredPoints()
Returns the number of acquired points in the phase data record.
