Performance Check/Calibration—Type 422 AC-DC
Fig. 5-7. Location of high-voltage test point (rear panel, socket
cover removed).
b.
Adjust the FOCUS and ASTIGMATISM controls for a
well defined display.
Fig. 5-8. Location of Unblanking Center adjustment (Horizontal
Amplifier board).
d. Set the Channel 1 VO LTS/DIV switch so the large
markers extend beyond the top and bottom o f the graticule
area.
c.
CHECK—Trace should be parallel to the center
horizontal line w ithin 0.1 division/10 divisions (i.e., with
trace positioned to center horizontal line at the left vertical
line o f the graticule, the trace must be w ithin 0.1 division
of the center horizontal line at the right vertical line).
e. CHECK—Markers should be parallel to the center
vertical line w ithin 0.1 division.
f. ADJUST—Y Axis Align adjustment R856 (see Fig.
5-10) so the markers are parallel to the center vertical line.
NOTE
This tolerance is provided as a guide to correct
instrument operation and is not an instrument
specification.
d.
ADJUST—Trace rotation adjustment R851 (see Fig.
5-9) so the trace is parallel to the center horizontal line.
NOTE
If the Trace Rotation adjustment does not have
enough range to make the trace parallel w ith the
horizontal graticule lines, reverse the connection of
these leads at the Horizontal A m p lifie r board.
11. Check/Adjust Y Axis Alignment
a. Connect the time-mark generator (Type 184) to the
INPUT 1 connector w ith the 42-inch BNC cable.
b. Set the time-mark generator for output markers of
one and 0.1 millisecond.
c. Set the LEVEL control fo r a stable display.
