□ SteP 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 division standard-amplitude
signal.
c. Press in the SAVE/CONT button to select SAVE.
d. Set the CH 1 VOLTS/DIV switch to 10 mV and reposition the display.
e. CHECK^The display is expanded to five divisions in amplitude.
f. Set;
CH 1 VOLTS/DIV 0.1 V
SAVE/CONT CONT
g. Set the generator to produce a five division standard-amplitude
signal.
h. Press in the SAVE/CONT button to select SAVE.
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.
l. Set:
