Performance Check Procedure—2230 Service
c. 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.
d. Repeat part b using the Channel 2 controls.
2. Check Store Deflection Accuracy
a. Set:
CH 2 VOLTS/DIV 2 mV
STORE/NON STORE STORE (button in)
POSITION CURS/
SELECT WAVEFORM POSITION CURS
(button in)
b. Use the CURSORS control and SELECT C1/C2
switch to set one cursor at the bottom and the other cur
sor at the top of the square wave.
c. CHECK—Deflection accuracy is within the limits
given in Table 4-3 for each CH 2 VOLTS/DIV switch set
ting and corresponding standard-amplitude signal.

d. 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.
e. Repeat parts b and c using the Channel 1 controls.
3. Check Save Expansion and Compression
a. Set the CH 1 VOLTS/DIV switch to 0.1 V.
b. Set the generator to produce a 0.5 div standard-
amplitude signal.
c. Set the SAVE/CONTINUE switch to SAVE
(button in).
d. Set the CH 1 VOLTS/DIV switch to 10 mV and
reposition the display.
e. CHECK—The display is expanded to 5 divisions in
amplitude.
f. Set:
CH 1 VOLTS/DIV 0.1 V
SAVE/CONTINUE CONTINUE (button out)
g. Set the generator to produce a 5 division standard-
amplitude signal.
h. Set the SAVE/CONTINUE switch to SAVE
(button in).
i. Set the CH 1 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 1 OR X input connector
to the CH 2 OR Y input connector.
I. Set:
VERTICAL MODE CH 2
