Set the Mode Selector 21 to N.
b. Apply suitable trigger pulses to the
TRIGGER INPUT socket 16.
c.
Set the PULSE PERIOD switch 1 to
EXT+ for positive trigger input pulses
or to EXT- for negative trigger input
pulses.
d. Set the delay between the trigger and
output pulses as described in para¬
graph 3—6,
e.
Set the width, amplitude, risetime,
falltime, polarity and offset of the
output pulses as described in para¬
graph 3-6.
