Performance Check Procedure— 2236 Service
i. Set the generator to produce a 50-kHz, 6-division
display.
j. Set the VERTICAL MODE switch to BOTH.
k. Adjust the CH 1 or CH 2 VOLTS/DIV Variable control
for minimum display amplitude.
l
. Set the VERTICAL MODE switch to CH 1.
m. Set the generator to produce a 50-MHz, 6-division
display.
n. Set the VERTICAL MODE switch to BOTH.
o. CHECK— Display amplitude is 0.6 division or less.
p. Disconnect the test equipment from the instrument.
g. Set:
VERTICAL MODE
CH 1
Channel 1 Input Coupling
GND
Channel 2 Input Coupling
DC
h. CHECK— Display amplitude is 0.05 division or less.
i. Disconnect the test equipment from the instrument.
9. Check External Z-Axis Operation
a. Set:
CH 1 VOLTS/DIV
1 V
Channel 1 Input Coupling
DC
A SEC/DIV
20
ms
b. Connect the leveled sine-wave generator output via a
50-fi cable and a T-connector to the CH 1 OR X input con
nector. Then connect a 50-0 cable and a 50-0 termination
from the T-connector to the EXT Z AXIS INPUT connector
on the rear panel.
8. Check Channel Isolation
a. Set:
VERTICAL MODE
VOLTS/DIV (both)
VOLTS/DIV Variable (both)
INVERT
Channel 2 Input Coupling
A SEC/DIV
CH 1
1 V
CAL detent
Off (button out)
GND
0.1
ms
c. Set the generator to produce a 5-V, 50-kHz signal.
d. CHECK— For noticeable intensity modulation. The
positive part of the sine wave should be of lower intensity
than the negative part.
e. Disconnect the test equipment from the instrument.
b. Connect the leveled sine-wave generator output via a
50-0 cable and a 50-0 termination to the CH 1 OR X input
connector.
c. Set the generator to produce a 50-MHz, 5-division
display.
d. Set the VERTICAL MODE switch to CH 2.
10. Check Probe Adjust Operation
a. Set:
CH 1 VOLTS/DIV
10 mV
A SEC/DIV
0.5 ms
b. Connect the 10X Probe to the CH 1 OR X input con
nector and insert the probe tip into the PROBE ADJUST
jack on the instrument front panel. If necessary, adjust the
probe compensation for a flat-topped square-wave display.
e. CHECK— Display amplitude is 0.05 division or less.
c. CHECK— Display amplitude is 4.75 to 5.25 divisions.
f. Move the cable from the CH 1 OR X input connector to
the CH 2 OR Y input connector.
4-8
d. Disconnect the probe from the instrument.
