(1) Attributes can only be set while the device is in Program Mode. See the description of the Device Mode Object
for more information.
12 Get Data Format USINT The format of the
spectrum data. 0 = Complex 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
