54. Check A LEVEL Control External Range
a. Set both SOURCE switches to EXT, the CH 1
VOLTS/DIV 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 LEVEL control throughout its range.
e. CHECK—CRT display is not triggered at either
extreme of the A LEVEL 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 LEVEL control throughout its range.
h. CHECK—Repeat step 54-e.
i. Set the CH 1 VOLTS/DIV switch to 10 V and the A
SOURCE switch to EXT 10.
j. Adjust the Low-Frequency generator for a four
division display of a 1 kilohertz signal.
Calibration—475
k. CHECK—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 LEVEL control throughout its
range.
l. CHECK—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 LEVEL control throughout its
range.

55. Check B LEVEL Control External Range
a. Set the HORIZ DISPLAY switch to B DLY'D, the A
SOURCE switch to NORM, the B SLOPE switch to +, and
the CH 1 VOLTS/DIV 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.

point along the positive slope of the displayed waveform
when rotating the B LEVEL control throughout its range.
e. CHECK—CRT display is not triggered at either
extreme of the B LEVEL control.
f . Set the B 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 B LEVEL control throughout its range.
