c. Set the standard amplitude calibrator for a fivt .1illi-
volt square-wave output.
d. CHECK-CRT display five divisions or greater in ampli-
tude (one millivolt/division, or
less, minimum deflection
factor).
1 8. Check Channel 1 and 2 Input Coupling
Switch Operation
a. Set the CH 1 and CH 2 VOLTS/DIV switches to 20 mV.
h. Disconnect the 18-inch BNC cable from the Channel 2
INPUT connector and reconnect the standard amplitude cali-
brator to the Channel 2
INPUT connector.
c. Set the standard amplitude calibrator for a SO-millivolt
square-wave output.
d. Position the display with the Channel 2 POSITION con-
trol
so the bottom of the square wave is at the center hori-
zontal line.
e. Set the Channel 2 Input Coupling switch to GND.
f. CHECK-CRT display for straight line near the center
horizontal line.
g. Set the Channel 2 Input Coupling switch to AC.
h. CHECK-CRT display centered about center horizontal
line.
i. Set the MODE switch to CH 1.
j. Position the display with the Channel 1 POSITION con-
trol
so the bottom of the square wave is at the center hori-
zontal line.
k. Set the Channel 1 Input Coupling switch to GND.
I. CHECK-CRT display for straight line near the center
horizontal
line.
m. Set the Channel 1 Input Coupling switch to AC.
n. CHECK-CRT display centered about center horizontal
line.
19. Check Low-Frequency Vertical Linearity
a. Set the Channel 1 and 2 Input Coupling switches to DC.
b. Position the display to the center of the graticule with
the Channel 1 POSITION control.
c. Adjust the Channel 1 VARIABLE control for exactly two
divisions
of deflection.
d. Position the top of the display to the top horizontal line.
e. CHECK-Compression or expansion 0.15 division or less
(see Fig. 5-15).

f. Position the bottom of the display to the bottom hori-
zontal line.
:g. CHECK-Compression or expansion 0.15 division or
less (see Fig. 5-15).
h. Set the MODE switch to CH 2.
i. Position the display to the center of the graticule with
the Channel 2 POSITION control.
j. Set the Channel 2 VARIABLE control for exactly two
divisions
of deflection.
k. Position the top of the display to the top horizontal
line.
I. CHECK-Compression or expansion 0.15 division or
less (see Fig. 5-15).
