(13) Connect oscilloscope calibrator CHAN 1 to TI CH 1 using a 50Ω feedthrough
termination.
(14) Position controls as listed in (a) through (c) below:
(a) VERTICAL MODE CH 1 BOTH CH 2 switch to CH 1.
(b) CH 1 and CH 2 VOLTS/DIV switches to 2m.
(c) Set A AND B SEC/DIV switch to .05 s.
(15) Press oscilloscope calibrator EDGE pushbutton to illuminate green LED and set
oscilloscope calibrator output to 10 mV at 1 MHz.
(16) Use technique of step 17 below for TI settings and oscilloscope calibrator output
settings listed in table 5.
(17) Adjust CH 1 POSITION control to position top of waveform to center horizontal
graticule line. If squarewave aberrations exceed those listed in table 5, perform
adjustments listed in table 5.
