b. While monitoring generator No. 1 output
with oscilloscope, set No. 1 generator
controls as follows:
1. REP RATE to Ik-10k with adjust-
ment centered.
2. PULSE WIDTH for .2 /^sec pulse at
2 V amplitude.
3. PULSE POLARITY to +.
c. While monitoring generator No.2 output
with oscilloscope, set No. 2 generator
controls as follows:
1. REP RATE to MAN/EXT +.
2. PULSE POLARITY to +.
3. PULSE WIDTH for .2 A/sec pulse at
2 V amplitude.
4. PULSE DELAY for .5 /jsec.
d. Set Oscilloscope DISPLAY control to
A + B to monitor No.2 pulse position.
e. Set 5304A control as follows:
1. ATTEN (both channels) to XI.
2. AC-DC (both channels) to DC.
3. SLOPE (both channels) to +.
4. LEVEL (both channels to PSET.
5. COM-SEP-CHK to SEP.

f. 5304A should display 00000.5 psec;
verify time interval with oscilloscope.
g. While monitoring oscilloscope, adjust No.
2 generator PULSE DELAY for time
intervals from .5 /jsec to 150 /jsec. 5300A
Display should be the same as oscil-
loscope display.
h. Set No. 1 generator REP RATE to 100-
lk and adjustment centered.
i. While monitoring oscilloscope, adjust
No. 2 generator PULSE DELAY for time
intervals from 150 /jsec to 2000 /jsec.
5300A display should be the same as
oscilloscope display.
j. Set No. 1 generator REP RATE to 10-100
and adjustment full ccw.
k. While monitoring oscilloscope, adjust
No. 2 generator PULSE DELAY for time
intervals from 2000 /jsec to 6000 /jsec.
5300A display and oscilloscope display
should indicate the same time intervals.
NOTE
Measurement resolution may be
adjusted from .1 |j.sec to 1 msec
with the T.I. \ to B switch.
