Burst
DG2000 can output the waveforms with a specified number of cycles (Burst) from a
single channel or from dual channels at the same time. DG2000 supports control of
burst output by internal, manual or external trigger source; supports three kinds of
burst types, including N cycle, Infinite, and Gated. The generator can generate burst
by using Sine, Square, Ramp, Pulse, Noise (only for gated burst), arbitrary waveform,
PRBS, RS232, or Sequence.
To Enable the Burst Function
When the Shift key is illuminated, press Home/Menu → Burst to select "NCycle",
"Infinite", or "Gated" to enable the pulse function. The Modulation or Sweep
function will be disabled automatically (if enabled currently). At this time, the
generator will output burst waveform from the corresponding channel (if currently
turned on) according to the current configuration. You can also reset the burst
function menu. Please refer to the following section for details.
Burst Type
DG2000 can output three types of bursts, including N cycle, Infinite and Gated.

Note

: When the waveform points ≥128, the output cycle is 1; when the waveform
points < 128, the output cycle is Ceiling (128/waveform points).
N Cycle
In N Cycle mode, the generator will output waveforms with a specified number of
cycles after receiving the trigger signal.
When the Shift key is illuminated, press Home/Menu → Burst → "NCycle" to
enable the N Cycle burst. Tap the Cycles menu label, then use the numeric keypad
to input the number of cycles. You can also use the arrow keys and the knob to
modify the number of cycles. The default is 1, and the range is from 1 to 1,000,000
(external or manual trigger) or from 1 to 500,000 (internal trigger).
