c. Adjust the CH 2 VOLTS/DIV Variable control to pro
duce a 4.4-division display. Set the CH 2 VOLTS/DIV switch
to 10 mV.
Performance Check Procedure— 2236 Service
d. CHECK— Rotating the Channel 2 POSITION control
fully counterclockwise positions the top of the trace below
the center horizontal graticule line.
e. CHECK— Rotating the Channel 2 POSITION control
fully clockwise positions the bottom of the trace above the
center horizontal graticule line.
j. Set the A EXT COUPLING switch to DC -=- 10.
k. Set the generator to produce a 5-V signal.
l
. Repeat parts b and c.
m. Disconnect the test equipment from the instrument.
f. Move the cable from the CH 2 OR Y input connector to
the CH 1 OR X input connector. Set the VERTICAL MODE
switch to CH 1.
g. Repeat parts c through e using the Channel 1
controls.
3. Check Trigger View Gain
a. Set:
Vertical POSITION (both)
Midrange
VOLTS/DIV (both)
0.1 V
VOLTS/DIV Variable (both)
CAL detent
4. Check Aberrations
a. Set:
VERTICAL MODE
BW LIMIT
VOLTS/DIV (both)
Input Coupling (both)
A SEC/DIV
A SOURCE
CH 1
Off (button out)
2 mV
DC
0.05 fis
INT
b. Connect the fast-rise, positive-going square-wave
output via a 5042 cable, a 10X attenuator, and a 50-12 termi
nation to the CH 1 OR X input connector.
b. While holding in the TRIG VIEW button, use the
A TRIGGER LEVEL control to vertically center the display.
c. Set the generator to produce a 1-MHz, 5-division
display.
c. CHECK— Display amplitude is 4 to 6 divisions while
holding in the TRIG VIEW button.
d. CHECK— Display aberrations are within 5% (0.25 di
vision or less).
d. Move the cable from the CH 1 OR X input connector
to the CH 2 OR Y input connector. Set the VERTICAL
MODE switch to CH 2.
e. Repeat parts b and c.
f. Move the cable from the CH 2 OR Y input connector to
the EXT INPUT connector. Set the A SOURCE switch to
EXT.
g. Repeat parts b and c.
h. Set the A EXT COUPLING switch to DC.
i. Repeat parts b and c.
e. Set the CH 1 VOLTS/DIV switch to 5 mV.
f. Set the generator to produce a 5-division display.
g. CHECK— Display aberrations are within 4% (0.2 divi
sion or less).
h. Repeat part g for each of the following VOLTS/DIV
switch settings: 10 mV through 0.5 V. Adjust the generator
output and attach or remove the 10X attenuator as neces
sary to maintain a 5-division display at each VOLTS/DIV
switch setting.
i. Disconnect the cable from the CH 1 OR X input con
nector. Reconnect the 10X attenuator (if previously re
moved) and reduce the generator amplitude to minimum.
