Burst Mode
Burst Count
Number of cycles (1 to 100,000,000 or infinite) to be output per burst. Used in the triggered burst mode only (internal
or external source).
l
With Internal trigger source, specified number of cycles are output continuously at a rate determined by burst
period. The burst period is the time between the starts of consecutive bursts. Also, the burst count must be less
than the product of burst period and waveform frequency:
Burst Period > (Burst Count)/(Waveform Frequency) + 1µsec
l
The instrument will increase burst period to its maximum value to accommodate specified burst count (but wave-
form frequency will not be changed).
l
In gated burst mode, burst count is ignored. However, if you change the burst count from the remote interface
while in the gated mode, the instrument remembers the new count and will use it when the triggered mode is
selected.

Burst Period
Burst period is the time from the start of one burst to the start of next burst (1 µs to 8000 s, default 10 ms). Used in
internal triggered burst mode only. Burst period differs from "waveform frequency," which specifies the frequency of
the bursted signal.
l
Burst period is used only when Immediate triggering is enabled. The burst period is ignored when manual or exter-
nal triggering is enabled (or when the gated burst mode is selected).
l
You cannot specify a burst period that is too short for the instrument to output with the specified burst count and
frequency. If the burst period is too short, the instrument will increase it as needed to continuously re-trigger the
burst.
