Irregular external width
input pulses (INPUT 22).
Positive output pulses
(OUTPUT 20).
Note: A small delay exists between the
input and output pulses.
Output pulses may be negative
and the output pulse baseline
offset as shown in figure 3-2.

When operating in the RZ or EXT.WIDTH
modes, the internal oscillator is available for use as an
independent
clock
generator
(figure
3—14)
which
provides an output at the TRIGGER OUTPUT connec¬
tor 17.
This output may be triggered
internally,
externally,
or
manually, and in addition gated, as
described for the normal operating mode (paragraph
3-3). If this facility is not required, it may be switched
off by setting the PULSE PERIOD control 1 to EXT and
disconnecting the TRIGGER INPUT 16.
