Burst Type
You can use burst in one of two modes as described below. The function
generator enables one burst mode at a time based on the trigger source
and burst source that you select (see the table below).
• Triggered Burst Mode: In this mode (default), the function 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 function generator stops and waits for the next
trigger. You can configure the function 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 Trig In 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 Trig In connector. When the gate signal is true,
the function generator outputs a continuous waveform. When the
gate signal goes false, the current waveform cycle is completed and
then the function 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.
