Burst Period
Burst period is only available for internally triggered N-Cycle burst mode (user-
defined burst count). Burst period is defined as the time from the start of a burst to
the time when the next burst starts.
Click or tap the Burst Period input field and use the pop-up numeric keypad to set
the period. It ranges from 4 μs to 8 ks and the default is 10 ms. The resolution is 0.1
ns.
•
Burst Period ≥ ⌈(Burst Count x Waveform Period) ÷ 6.4 ns⌉ x 6.4 ns + 4 μs
•
If the burst period is too short, the generator will increase it automatically to
allow the output of the specified number of cycles.
NOTE
[1]: ⌈x⌉ indicates that x is rounded up.

each time a TTL pulse with leading edge is received.
•
Ext Trailing: When external trailing edge is selected, the instrument receives the
trigger signal from the rear-panel [AUX IN/OUT] connector. A burst is generated
each time a TTL pulse with trailing edge is received.
