PROCEDURE STEPS
1. A d ju st V ertical Gain (R 1 8 6 , R 2 8 6 , R 1 4 5 , and
R 2 4 5 )
a. Connect a 100-mV standard-amplitude signal via a
5 0-ft cable to the CH 1 OR X input connector.
b. ADJUST— Ch 1 Gain (R186) fo r an exact 5-division
display.
c. Move the cable from the CH 1 OR X input connector
to the CH 2 OR Y input connector. Change the VER TICAL
MODE switch to CH 2.
d. ADJUST— Ch 2 Gain (R286) fo r an exact 5-division
display.
e. Change the generator output to 10 mV and set the
CH 1 and CH 2 VO LTS/DIV switches to 2 mV.
f. ADJUST—Ch 2 X10 Vert Gain (R245) fo r an exact
5-division display.
g. Move the cable from the CH 2 OR Y input connector
to the CH 1 OR X input connector. Change the VER TICAL
MODE switch to CH 1.
h. ADJUST— Ch 1 X10 Vert Gain (R145) fo r an exact
5-division display.
