Adjustment Procedure— 2236 Service
18. Check Channel Isolation
a. Set:
VOLTS/DIV (both)
1 V
Channel 1 Input Coupling
GND
A SEC/DIV
0.1 tis
b.
Set the generator to produce a 50-MHz, 5-division
display.
c. Set the VERTICAL MODE switch to CH 1.
d. CHECK— Display amplitude is 0.05 division or less.
e.
Move the cable from the CH 2 OR Y input connector to
the CH 1 OR X input connector.
f. Set:
VERTICAL MODE
CH 2
Channel 1 Input Coupling
DC
Channel 2 Input Coupling
GND
g. CHECK— Display amplitude is 0.05 division or less.
h. Disconnect the test equipment from the instrument.
19. Check Common-Mode Rejection Ratio
a. Set:
VOLTS/DIV (both)
10 mV
INVERT
On (button in)
Channel 2 Input Coupling
DC
A SEC/DIV
50 jus
b.
Connect the leveled sine-wave generator output via a
50-0 cable, a 50-0 termination, and a dual-input coupler to
the CH 1 OR X and CH 2 OR Y input connectors.
c.
Set the generator to produce a 50-MHz, 6-division
display.
d.
Vertically center the display using the Channel 2 POSI
TION control. Then set the VERTICAL MODE switch to CH
1 and vertically center the display using the Channel 1 PO
SITION control.
e. Set the VERTICAL MODE switches to BOTH and
ADD.
f. CHECK— Display amplitude is 0.6 division or less.
g. If the check in part f meets the requirement, skip to
part p. If it does not, continue with part h.
h. Set the VERTICAL MODE switch to CH 1.
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.
I. 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.
20. Check External Z-Axis Operation
a. Set:
VERTICAL MODE
CH 1
CH 1 VOLTS/DIV
1 V
VOLTS/DIV Variable (both)
CAL detent
INVERT
Off (button out)
A SEC/DIV
20
ms
b.
Connect the leveled sine-wave generator output via a
50-0 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.
