Spectrum Waveform
Measurement Object
(Class ID 324
H
)
The Spectrum/Waveform Measurement Object models a spectrum and
waveform measurement.
When requesting the first byte of waveform or spectra data, the module copies
the most recently sampled live measurement to a hold buffer. This buffer holds
measurement until the entire measurement is uploaded to the host, or until a
new first byte request is made. If the measurement mode is Synchronous, and
the channels have the same number of orders and number of lines, then when
the first byte of the channel 0 data is requested. The module copies the
simultaneous measurements for both channel 0 and channel 1 to the hold
buffer.
Class Attributes
The Spectrum/Waveform Measurement Object provides no class attributes.
Instances
There are four instances of this object. Instances 1 and 2 are the standard
spectrum (and waveform) for channels 1 and 2, respectively. Instances 3 and 4
are the gSE spectrum for channels 1 and 2, respectively. Instance 3 and 4
support the gSE spectrum only and not a waveform. Also, instances 3 and 4 do
not support the Complex Data Format.
