Using the Agilent 81101A
The Mode/Trigger Screen
Gated Burst Mode
The following figures show typical timings for trigger mode GATED and
pulse mode BURST.
For the first example, the synchronously triggerable internal oscillator is
used to source the period.
Characteristics
Bursts of pulse periods are gated by (enabled by) an active level at
the selected arming source:
MAN key on the front panel, gated while pressed or released or
both.
EXT INPUT (external signal) gated by high, low or both levels.
You can select single pulses or double pulses per pulse period.
TRIGGER OUT marks each pulse period.
STROBE OUT rises at the start of the first pulse period in a burst and
falls at the start of the last pulse period.
