Burst Mode
The instrument can output a waveform for a specified number of cycles, called a burst. Burst is allowed with sine,
square, triangle, ramp, pulse, PRBS, or arbitrary waveforms (noise allowed only in gated burst mode; DC is not
allowed).
For details, see Tutorial -
To Select Burst
Burst cannot be enabled when sweep or modulation is enabled. Enabling burst turns off sweep and modulation.
To avoid multiple waveform changes, enable burst mode after configuring other parameters.

Burst Mode
Burst has two modes, described below. Selected mode controls allowable trigger source, and which other burst param-
eters apply.
Triggered Burst Mode (default): The instrument outputs a waveform for specified number of cycles (burst
l
count) each time trigger is received. After outputting specified number of cycles, instrument stops and waits for
next trigger. The instrument can use an internal trigger to initiate burst, or you can provide external trigger by
pressing the front-panel Trigger key, applying trigger signal to rear-panel Ext Trig connector, or sending software
trigger command from remote interface.
External Gated Burst Mode: Output waveform is on or off, based on level of external signal applied to rear-panel
l
Ext Trig connector. When the gate signal is true, the instrument outputs a continuous waveform. When the gate
signal goes false, the current waveform cycle is completed and the instrument stops while remaining at the volt-
age level corresponding to the starting burst phase of the selected waveform. The noise waveform output stops
immediately when the gate signal goes false.
