Using the Agilent 81101A
The Mode/Trigger Screen
Gated Pulses Mode
The following figures show typical timings for trigger mode GATED and
pulse mode PULSES.
For the first example, the synchronously triggerable internal oscillator is
used to source the period.
Characteristics
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 is not used in gated pulses mode.
