(5) Connect oscilloscope calibrator to TI SCOPE IN using 50 Ω feedthrough
termination.
(6) Press Sweep (F3) key, adjust DATA SCROLL knob to select 20 s, and press
DATA ENTRY ENTER key.
(7) Press Scale (F1) key, adjust DATA SCROLL knob to select 10 mV, and press
DATA ENTRY ENTER key.
NOTE
If necessary, press Vert (F2) key and use DATA SCROLL
controls to position waveform vertically on display.
(8) Set oscilloscope calibrator level sine output for 50 kHz and 6 divisions of vertical
deflection on TI.
(9) Set oscilloscope calibrator leveled sine wave frequency to 1 MHz. Press Sweep
(F3) key and use DATA SCROLL controls, as necessary, to view waveform. Displayed
waveform will be greater than 4.2 divisions.
(10) Repeat technique of (6) through (9) above for Scale 100 mV.
NOTE
For (11) through (15) below; press Scale (F1) key, use DATA
SCROLL controls to set convenient display amplitude, press
Vert (F2) key, and use DATA SCROLL controls to position
markers vertically on display as necessary.
(11) Press Sweep (F3) key, adjust DATA SCROLL knob to select 1 s, and press
DATA ENTRY ENTER key.
(12) Set oscilloscope calibrator markers output for 1 s.
