Burst Mode
You can use burst in one of two modes as described below. The selected
mode controls the allowable trigger source that you selected, and
whether certain other burst parameters apply (see the table below).
• Triggered Burst Mode : In this mode (default), the waveform
generator outputs a waveform with a specified number of cycles
(
burst count ) each time a trigger is received. After the specified
number of cycles have been output, the waveform generator stops and
waits for the next trigger. You can configure the waveform generator
to use an internal trigger to initiate the burst or you can provide an
external trigger by pressing the front-panel
key, applying a
trigger signal to the rear-panel Ext Trig connector, or sending a
software trigger command from the remote interface.
• External Gated Burst Mode : In this mode, the output waveform is
either “on” or “off ” based on the level of the external signal applied
to the rear-panel
Ext Trig connector. When the gate signal is true ,
the waveform generator outputs a continuous waveform. When the
gate signal goes
false , the current waveform cycle is completed and
then the waveform generator stops while remaining at the voltage
level corresponding to the starting burst phase of the selected
waveform. For a noise waveform, the output stops immediately when
the gate signal goes false.
