Burst
DG800 can output the waveforms with a specified number of cycles (Burst) from a
single channel or from dual channels at the same time. DG800 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
Press 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
DG800 can output three types of bursts, including N cycle, Infinite and Gated.

Type Trigger Source Carrier Waveform
N Cycle Internal/External/Manual Sine, Square, Ramp, Pulse, Arbitrary
Waveform, PRBS, RS232, Sequence
Infinite External/Manual Sine, Square, Ramp, Pulse, Arbitrary
Waveform, PRBS, RS232, Sequence
Gated External Sine, Square, Ramp, Pulse, Noise, Arbitrary

N Cycle
In N Cycle mode, the generator will output waveforms with a specified number of
cycles after receiving the trigger signal.
Press 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).
