(14) Set oscilloscope calibrator output and frequency as listed in table 13.
(15) Rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton to
obtain TI display divisions listed in table 13. Measure risetime using standard risetime
techniques. Risetime will be within limits as specified in table 13 for oscilloscope series
being used.
