c.
Move the cabie 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 CH 2 controls.
Step 2: Check Store Deflection Accuracy
a.
Set:
CH 2 VOLTS/DiV
STORE/NON-STORE
Acquisition MODE
b. Set the generator to produce a five division standard amplitude
signal.
c.
Use the CURSORS control and SELECT C1/C2 switch (push in the
CURSORS controls knob) to set one cursor at the bottom of the
square wave and the other cursor at the top of the square wave.
d. CHECK — Deflection accuracy is within the limits given in Table A-9
for each CH 2 VOLTS/DIV switch setting and corresponding stan­
dard-amplitude signal.
e.
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.
f.
Repeat parts b and c using the CH 1 controls.
