Triggered Burst Mode

The following figures show typical timings for trigger mode TRIGGERED
and pulse mode BURST. The bursts are triggered by the rising edge of the
arming source.
For the first example, the synchronously triggerable internal oscillator is
used to source the period.

– MAN key on front panel, triggered by press or release or both.
– EXT INPUT triggered by rising or falling or both edges.
– PLL (internally triggered bursts)
When using the internal PLL as the arming source, you must specify
the triggering period.
