S1 (SS)
In this mode, S2 is synchronous with S1. Each S1 pulse will produce an
S2 pulse. If delay is required between the S1 and S2 pulses, the
S2 DELAY
can be used.
For example, it is desired to deliver monophasic pulses at the same pulse
rate of 50 PPS from S1 and S2 outputs but separated by a 20 millisecond
delay. Note that the pulse durations and output voltages can be the same
or
different. The following procedure lists the settings.
1. Select S1 FUNCTION , then S1 REPEATING PULSES (RP).
2. Select S1 PULSES
,
then MONOPHASIC
.
3. Select TIMING RATE
,
and set to 0050.00 PPS.
4. Select TIMING DELAY and set to minimum.
5. Select TIMING DURATION and set to desired pulse duration (observe
50 % duty cycle limit).
6. Select S2 FUNCTION , then FUNCTION = SYNC WITH S1 (SS).
7. Select S2 PULSES
,
then MONOPHASIC.
8. Select TIMING DELAY and set to
00.0200
(seconds).
9. Select TIMING DURATION and set to desired pulse duration (observe
50% duty cycle limit).
10. Turn the S1 and S2 OUTPUT ON/OFF to on .
