Burst Mode
In Burst mode, the module starts waveform generation when it is armed and receives the trigger signal, as in Gated mode. However, instead of repeating continuously, the waveform starts, repeats, and stops after a finite number of repetitions. The number of the repetitions can be specified by the property Burst Count via the GUI or API-based applications. The Burst Count property can be set from 1 to 255. Trigger signals received before the waveform stops will be ignored. Once the waveform stops, the module will arm itself automatically and await the next trigger signal.
The following figure shows waveform generation for different Burst Counts: 1, 2, and 3.
Until Loop Done is reached at the end of completing the number of loops in Burst Count, the module repeats the waveform continuously. There is no latency between consecutive waveforms within a burst. The following waveform starts right after the end of the preceding waveform. After the module receives the next trigger signal, it repeats this process. The waveform generation can be aborted by an Abort command from the GUI or API-based applications.
» With the program open, click on the Waveform tab if you are not already in the Waveform Panel.
» Click on the drop-down list and select one of the saved waveforms, such as "1/32 Sine (sine_1o32.wfa)", which is a Sine wave at 1/32th of the clock frequency. The files have the extension .wfa and are stored in your application folder or the user-defined waveform directory. You can adjust various parameters if desired.
Click on the Download button near the bottom of the window or in the toolbar. Wait several seconds for the file to finish downloading.
Check the Burst Mode box on the waveform tab and specify the number of loops that the waveform will run through.
Finally, apply a trigger signal, either via the TRIG SMA on the module or by enabling the Auto Trigger in the Configuration section of the Configuration & Status Tab.
