(6) Repeat technique of steps (2) through (5) above for appropriate series
oscilloscope.
(7) Set DISPLAY MODE switch to CH 2.
(8) Set CH 2 VOLTS/DIV switch as listed in 1st row of table 7.
(9) Ensure oscilloscope calibrator CHAN 2 is connected to TI CH 2 using a 50Ω
feedthrough termination. Press oscilloscope calibrator CHANNEL pushbutton then press
blue soft pushbutton located below CHAN 2 on oscilloscope calibrator display.
(11) Rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton to
obtain oscilloscope display divisions as listed in table 7. Measure risetime using standard
risetime techniques. Risetime will be within limits as specified in table 7; if not, perform b
below.
