d. Using Table 5-4, check magnified timing accuracy
(columns
3 and 4) for each of the TIME/DIV settings listed
in column 1. Set Time Mark Generator as shown in
column 2.

4. Check External Horizontal Deflection Factor
a. Set INTENSITY control fully counterclockwise.
b. Set TIME/DIV to EXT HORIZ X10, and TIME/DIV
Variable to CAL. Turn INTENSITY control clockwise to
produce a spot on graticule.
7----
CAUTION 1
High intensity spot can burn phosphor.
c. Set TRIGGERING Source to EXT/LINE (INT button
out) and TRIGGERING Source to EXT DC (AC and AC LF
REJ buttons in).
d. Set EXT ATTEN to 1X.
e. Connect Standard Amplitude Calibrator to EXT
TRlG OR HORlZ INPUT connector.
f. Set Standard Amplitude Calibrator for 0.1 V
square-
wave.
g. CHECK-horizontal deflection (between spots) is 4
to 6 divisions.
h. Switch TIMEIDIV to EXT HORlZ XI, and Standard
Amplitude Calibrator to 1-volt square-wave.
i. CHECK-horizontal deflection (between spots) is
4
to 6 divisions.
j. Turn TIME/DIV Variable fully counterclockwise.
k. CHECK-not more than l/lOthedeflection noted in
part
i.
I. Switch Standard Amplitude Calibrator to 2-volt
square-wave.
m. Adjust TIMEIDIV Variable for exactly
5 divisions
between spots.
n. Switch EXT
ATTEN to 10X. Switch Standard
Amplitude Calibrator output to 20-volt square-wave.
o. CHECK-horizontal deflection should be between
4.9 and 5.1 divisions.
p. Return VOLTS/DIV Variable to CAL position.
5. Check External Horizontal Bandwidth
a. Connect Function Generator through a 50-ohm
cable and 50-ohm termination to EXT TRlG OR HORlZ
INPUT connector.
b. Switch EXT
ATTEN to XI, TIME/DIV to EXT HORlZ
XI, and TRIGGERING Source to EXT (INT button out).
c. Set Function Generator frequency to 10 kHz and
amplitude for 10 divisions of horizontal deflection.
d. Increase generator frequency until the horizontal
trace has shortened to 7.1 divisions.
e. CHECK-the generator frequency should be at
least 200 kHz.
f. Remove the generator from EXT TRlG OR HORIZ
INPUT connector.
