(8) Pull TI SEC/DIV variable knob out for X10 sweep magnification.
(9) Set oscilloscope calibrator for a CHAN 1, MARKER mode output of 10 ns/div.
(10) Set TI SEC/DIV to .05 s.
(11) Adjust TI TRIGGER LEVEL, INTENSITY, and CH 1 ⇕POSITION controls
for suitable viewing.
(12) Adjust TI ⇦POSITION⇨ control to align 1st time marker that is 50 ns beyond
start of sweep with 2nd vertical graticule line.
(13) Rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton to
align 5th time marker with 10th vertical graticule line. If oscilloscope calibrator err display
and TI linearity are not within limits specified in table 8, perform b below.
