center.
positive voltage that produces a barely triggered,
jittering display for each position (+ and -) of
SLOPE.
5. Rotate the A REF OR DLY POS control to align
the reference cursor with the bottom of the
waveform.
CHECK—The A Trigger Level readings are
within the limits given in the + Peak column of
Table 4-2.
6. Rotate the A control to align the delta cursor
with the top of the signal display.
7. CHECK—Vertical Deflection Accuracy (measured
against the graticule) and <AV Readout Accuracy
are within the limits listed in Table 4-2.
8. Set the TRIGGER LEVEL control at the most
10. Set the TRIGGER LEVEL control at the most
negative voltage that produces a barely trig-
gered, jittering display for each position (+ and
-) of SLOPE.
11. CHECK—The A Trigger Level readings are
within the limits given in the —Peak column of
Table 4-2.
