Burst Mode Overview
The following is an overview of the steps required to generate a burst.
You can use burst in one of two modes as described below. The function
generator enables one burst mode at a time.
• Triggered Burst Mode: In this mode (also called N Cycle Burst), 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 (manual) trigger by pressing the front-panel key,
applying a trigger signal to the rear-panel Trig In connector, or by
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.
