(6) Press TI upper select/adjust key to go to test 12. TI will display Verif 12.
(7) Set oscilloscope calibrator for a channel 2, 50 kHz, LEVEL SINE output. Adjust
oscilloscope calibrator output amplitude for a 6 division display on TI screen.
(8) Without changing oscilloscope output amplitude, switch TI to test 13 using
upper select/adjust key. TI will display Verif 13.
(9) Increase oscilloscope calibrator output frequency to 50 MHz. If TI vertical
displayed amplitude is not •4.2 divisions, perform b below.

a. Performance Check
(1) Press TI upper select/adjust key to go to test 14. TI will display Verif 14.
(2) Set oscilloscope calibrator for a channel 2, 100 MHz, LEVEL SINE output.
(3) Adjust oscilloscope calibrator output amplitude for a 4.5 division display on TI
screen. If TI will not trigger consistently, perform b below.
(4) Decrease oscilloscope calibrator output frequency to 60 MHz.
(5) Adjust oscilloscope calibrator output amplitude for a 2.0 division display on TI
screen. If TI will not trigger consistently, perform b below.

(7) Decrease oscilloscope calibrator output frequency to 10 MHz.
(8) Adjust oscilloscope calibrator output amplitude for a 1.5 division display on TI
screen. If TI will not trigger consistently on falling edge, perform b below.
(9) Set oscilloscope calibrator to STBY and press TI upper select/adjust key to go to
test 16. TI will display Verif 16.
(10) Set oscilloscope calibrator for a channel 1, 10 MHz, LEVEL SINE output.
(11) Adjust oscilloscope calibrator output amplitude for a 1.5 division display on TI
screen. If TI will not trigger consistently on falling edge, perform b below.
(12) Press TI upper select/adjust key to go to test 17. TI will display Verif 17.
(13) Increase oscilloscope calibrator output frequency to 100 MHz.
(14) Adjust oscilloscope calibrator output amplitude for a 4.5 division display on TI
screen. If TI will not trigger consistently, perform b below.
(15) Decrease oscilloscope calibrator output frequency to 60 MHz.
(16) Adjust oscilloscope calibrator output amplitude for a 2.0 division display on TI
screen. If TI will not trigger consistently, perform b below.
(17) Set oscilloscope calibrator output to STBY.
