(6) CH 1 and CH 2 AC-GND-DC switches to DC.
(7) BW switch to FULL.
a. Performance Check
(1) Connect oscilloscope calibrator CHAN 1 to TI CH 1 and connect oscilloscope
calibrator CHAN 2 to TI CH 2. Ensure oscilloscope calibrator CHAN 1 output is presently
selected by pressing oscilloscope calibrator CHANNEL pushbutton and then pressing blue
soft pushbutton located below CHAN 1 on oscilloscope calibrator display.
(3) Adjust CH 1 POSITION, oscilloscope, and time base controls as necessary to
(4) Adjust CH 1 (front panel) GAIN control for 5 divisions of display.
(6) Set CH 1 VOLTS/DIV switch as listed in 1st row of table 8 and rotate
oscilloscope calibrator knob located below EDIT FIELD pushbutton to obtain oscilloscope
display divisions as listed in 1st row of table 8. Oscilloscope calibrator err display will
indicate within limits as specified in table 8; if not, perform b(1) through (4) below.
(7) Repeat technique of steps (4) through (6) above for remaining rows listed in table
8. Oscilloscope calibrator err display indications will be within limits specified in table 8.

(8) Set DISPLAY MODE switch to CH 2.
(9) Set oscilloscope calibrator output to CHAN 2 using technique in step 1 above.
(10) Set oscilloscope calibrator VOLTAGE output to 50 mV at 1 kHz.
(11) Adjust CH 2 POSITION, oscilloscope, and time base controls as necessary to
(12) Adjust CH 2 (front panel) GAIN control for 5 divisions of display.
