Adjustment Procedure— 2230 Service
h. Set the SAVE/CONTINUE switch to SAVE (button
in).
i. Set the CH 2 VOLTS/DIV switch to 1 V.
j. CHECK—The display is compressed to 0.5 division
in amplitude.
k. Move the cable from the CH 2 OR Y input connector
to the CH 1 OR X input connector.
i. Set:
VERTICAL MODE
CH 1
SAVE/CONTINUE
CONTINUE (button out)
m. Repeat parts c through j.
n. Disconnect the test equipment from the instrument.
16. Adjust Attenuator Compensation
(C12, C11, C5, C4, C62, C61, C55, C54)
a. Set:
VOLTS/DIV (both)
0.1 V
STORE/NON STORE
NON STORE (button out)
b. Connect the high-amplitude square wave output via
a 50 0 termination, a probe-tip-to-BNC adapter, and the
10X probe to the CH 1 OR X input connector.
c. Set the generator to produce a 1 kHz, 5-division
display and compensate the probe using the probe com
pensation adjustment (see the probe instruction manual).
d. Set the CH 1 VOLTS/DIV switch to 0.1 V.
e.
Replace the probe and probe-tip-to-BNC adapter
with a 50
Q
cable.
f. Set the generator to produce a 5-division display.
NOTE
Use Table 5-5 to identify the correct capacitor for
each channel adjustment.
g. ADJUST—The 10X Attn (Cl 2) for best front corner.

k. Repeat parts e through j until no further improve
ment is noted.
l
. Set the CH 1 VOLTS/DIV switch to 1 V.
m. Replace the probe and probe-tip-to-BNC adapter
with the 50 S2 cable and 50 Si termination.
n. Set the generator to produce a 5-division display.
o. ADJUST—The 100X Attn (C5) for best front corner.
p.
