Manual
Triggering If a manual source is selected, the
trigger softkey (F1) must be
pressed each time to output a
burst.
Note When the internal trigger source is chosen, the
burst is output continuously at a rate defined by
the burst period setting. The interval between
bursts is defined by the burst period.
When the external trigger is selected the function
generator will receive a trigger signal (TTL) from
the Trigger INPUT terminal on the rear panel.
Each time the trigger is received, a burst is output
(with the defined number of cycles). If a trigger
signal is received during a burst, it is ignored.
When using the manual or external trigger only
the burst phase and burst cycle/count are
applicable, the burst period is not used.
A time delay can be inserted after each trigger,
before the start of a burst.
