Table 1-11. SWHP Circuit
Indication: Sweep
or
Ramp problems.
Check
1 . Depress CONT
(SWeep).
Extend SWPISTOP.
Check E48 for + 4V.
2. Depress SWP/STO
P
.
Check collector of 03. 4V peak ramp.
If ramp amplitude is
>
4V peak.
If ramp amplitude
is
< 4V peak.
4. At SWP OUT check for period change of approximately 30
ms
to 60s
as
the TI ME control is rotated from full
ccw
to full
cw
o
5
.
At SWP OUT
check
tor ramp period drift.
6. At E39 with STOP control full
cw,
ramp amplitude is 4V peak, with STOP
control full CCW, ramp amplitude is av.
