Adjustment Procedure—2213 Service
e. Set the X I0 Magnifier off (knob in).
g. ADJUST—5 ns Linearity (C734) for one time marker
every 2 divisions over the center 8 divisions of the mag
nified sweep. Adjust the Horizontal POSITION control to
f. CHECK—There is no discernable shift in the time
marker when switching between X I0 Magnifier on and X I0
Magnifier off.
check the linearity to the 15th time marker.
h. Repeat parts e through g until no further improve
ment is noted.
g. Turn the X10 Magnifier on (knob out) and repeat
parts b through e until no further improvement is noted.
i. Set the X I0 Magnifier off (knob in) and recenter the
trace using the Horizontal POSITION control.
3. Adjust 5-jus Timing (C626)
a. Set the SEC/DIV switch to 5 jus.
j. Repeat parts b through i until no further improve
ment is noted.
b. Select 5-jus time markers from the time-mark
generator.
5. Check Timing Accuracy
a. Select 50-ns time markers from the time-mark
generator.
c. ADJUST-5 jus Timing (C626) for 1 time marker per
division across the graticule area.
b. Use the Channel 1 POSITION control to center the
trace vertically. Adjust the TRIGGER LEVEL control
for a stable, triggered display.
4. Adjust High-Speed Timing (C754, C774, C784,
and C734)
a. Set the SEC/DIV switch to 0.05 jus.
c. Use the Horizontal POSITION control to align the
first time marker that is 50 ns beyond the start of the
sweep with the 2nd vertical graticule line.
b. Select 50-ns time markers from the time-mark
generator.
NOTE
When making timing measurements, use as a reference
the same point on each time marker.
c. ADJUST—50 ns Linearity (C754) for equally spaced
time markers at the start of the sweep.
d. CHECK—Timing accuracy is within the limits shown
in Table 5-6 for the applicable position of the X10 Mag
nifier. When making the check with the X10 Magnifier On,
d. Set the X10 Magnifier on (knob out) and select 10-ns
time markers from the time-mark generator.
exclude any portion of the sweep past the 100th magnified
division.
NOTE
Table 5-6
Timing Accuracy
In the next part, keep the adjustment screws for
C774 and C784 as close to the same length as possible.
X10 Magnifier Accuracy at 10th Vertical Graticule Line
e. ADJUST—5 ns Timing (C774 and C784) alternately
for one time marker every 2 divisions over the center 8
divisions of the magnified sweep.
Off (knob in) 3% (0.24 division)
On (knob out) 5% (0.40 division)
f. Adjust the Horizontal POSITION control so that the
5th time marker is aligned with the 2nd vertical graticule
line.
e. Repeat parts b through d for the SEC/DIV and time-
mark generator setting combinations shown in Table 5-7
under the "Normal" column.
