Command Groups
The DSA8300 programmable interface conforms to Tektronix standard codes
and formats except where noted. The GPIB interface also conforms to IEEE
Std 488.2-1987 except where noted.
Acquisition Command Group
Use the commands in the Acquisition Command Group to set up the modes and
functions that control how the instrument acquires the signals you input to the
channels and processes them into waveforms.
Using these commands for acquiring waveforms, you can do the following:
Start and stop acquisitions.
Control whether all waveforms are simply acquired, averaged, or enveloped
over successive acquisitions.
Set the controls or conditions that start and stop acquisitions.
Determine the action the system takes upon completing an acquisition, such
as saving all waveforms or saving the current display to a
fi le when the
acquisition is stopped.
Get data on acquired waveforms, histograms, and masks.
Get acquisition parameters.
Clear all acquired data.
