6 Get/Set FMAX REAL The maximum frequency
or order of the spectrum
data. 0...20000 Hz if
Domain = 0.
There are several predetermined
FMAX settings for which
spectrum data can be produced.
If you select an unsupported
value, then the next greater
supported FMAX value will be
used for the spectrum data.
4...40 Orders if
Domain = 1.The
Number of Lines value must
be evenly divisible by the FMAX
value or an Invalid Device
Configuration error will be
returned during the Device
Mode Object Start and Save
services.
7 Get/Set Number of
Spectrum Lines UDINT Number of lines or bins in
the spectrum data. 100, 200, 400, or 800
8 Get/Set Window Type USINT The window function to
be applied to the
waveform data prior to
computing the spectrum. 0 = Rectangular
1 = Hamming
2 = Hanning
3 = Flat Top
4 = Kaiser Bessel
9 Get/Set Period REAL The period of the
waveform. Seconds if
Domain = 0.
Cycles if
Domain = 1.
10 Get Number of
Waveform
Points UDINT Number of points in the
waveform data. 256, 512, 1024, or 2048
11 Get Overlap USINT The percent overlap
applied to the waveform
data sets used for
calculating the spectrum. Only 0% supported.
