n. C HECK—Repeat step 53-d.
o. Set the A SOURCE switch to E XT.
p. C HECK—Repeat step 53-c.
q. CHECK —Repeat step 53-d.
r. Disconnect the test setup.
54. Check A LEVEL Control External Range
a. Set both SOURCE switches to E XT, the CH 1
V O L T S /D IV switch to 1 V , the A SLOPE switch to +, and
the A COUPLING switch to AC.
b. Connect the output of the Low-Frequency Sine-Wave
Generator (General Radio 1310-A) to the CH 1 input and
the A External Trigger input through a BNC-T connector
and two 18-inch 50 12 BNC cables.
c. Adjust the Low-Frequency generator for a four
division display of a 1 kilohertz signal.
d. CHECK —That the display can be triggered at any
point along the positive slope of the waveform when
rotating the A LE V E L control throughout its range.
e. C HECK—CRT display is not triggered at either
extreme of the A LE V E L control.
f. Set the A SLOPE switch to —.
g. CHECK—That the display can be triggered at any
point along the negative slope of the displayed waveform
when rotating the A L E V E L control throughout its range.
h. CHECK—Repeat step 54-e.
i. Set the CH 1 V O L T S /D IV switch to 10 V and the A
SOURCE switch to E XT
10.
j. Adjust the Low-Frequency generator for a four
division display of a 1 kilohertz signal.
Calibration—475
k. C HECK —That the display can be triggered at any
point along the negative slope of the displayed waveform,
in the AC, HF REJ, and DC positions of the A COUPLING
switch, when rotating the A LEV E L control throughout its
range.
l
. C HECK —Repeat step 54-e.
m. Set the A SLOPE switch to +.
n. CHECK —That the display can be triggered at any
point along the positive slope of the displayed waveform, in
the AC, HF REJ, and DC positions of the A COUPLING
switch, when rotating the A LEV E L control throughout its
range.
o. C HECK —Repeat step 54-e.
55. Check B LEVEL Control External Range
a. Set the H O R IZ DISPLA Y switch to B D L Y 'D , the A
SOURCE switch to N O R M , the B SLOPE switch to +, and
the CH 1 V O L T S /D IV switch to 1 V.
b. Move the External Trigger signal to the B External
Trigger input.
c. Adjust the Low-Frequency generator for a four-
division display of a 1 kilohertz signal.
d. C HECK —That the display can be triggered at any
point along the positive slope of the displayed waveform
when rotating the B LE V E L control throughout its range.
e. C H EC K —CRT display is not triggered at either
extreme of the B LE V E L control.
f . Set the B SLOPE switch to —.
g. C H EC K —That the display can be triggered at any
point along the negative slope of the displayed waveform
when rotating the B LEV E L control throughout its range.
h. C HECK —Repeat step 55-e.
56. Check Single Sweep Operation
a. Set the H O R IZ D ISPLA Y switch to A and the A
COUPLING switch to AC.
