7 Get/Set Number of Spectrum
Lines UDINT Number of lines or bins in the
spectrum data. 100, 200, 400, 800, or 1600
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, 2048, or 4096
11 Get Overlap USINT The percent overlap applied to the
waveform data sets used for
calculating the spectrum. Only 0% supported.
12 Get/Set Data Format USINT The format of the spectrum data. 0 = Complex data
1 = Magnitude data
13 Get Average Type USINT The type of averaging performed. 0 = Asynchronous (spectrum)
1 = Synchronous (waveform)
Determined by the Synchronous
attribute of the Channel Object.
When set to Asynchronous, consecutive
spectrum measurements are averaged
together to produce the Spectrum data.
When set to synchronous, synchronized
waveforms are averaged together to
produce the Waveform data, and the
Spectrum data is produced from the
averaged waveform. A trigger source from
a tachometer, for example, is required to
obtain the synchronized waveforms.
14 Get/Set Number of Averages UINT The number of individual data sets
to be incorporated into the
average calculation. 0 = Invalid
1 = No averaging
> 1 = Averaging
15 Get/Set Storage Option BYTE Determines what must be stored
in response to a storage trigger
event. 1 = Store waveform
2 = Store spectrum
16 Get Storage Timestamp LTIME Records the timestamp of the
stored data. 64-bit microsecond counter value.
