(26) Pull TI A AND B SEC/DIV CAL knob out for X10 sweep magnification.
(27) Set oscilloscope calibrator for a CHAN 1, MARKER mode output of 10 ns/div.
(28) Set TI A SEC/DIV switch to .1 s and B SEC/DIV switch to .05 s.
(29) Adjust TI A and B TRIGGER LEVEL, B INTENSITY, and CH 1
⇕POSITION controls for suitable viewing.
(30) Adjust TI ⇦POSITION⇨ control to align 1st time marker that is 25 ns beyond
start of sweep with 2nd vertical graticule line.
(31) 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 13, perform b (25) through (28)
below.

(32) Set TI A SEC/DIV switch to .2 s and B SEC/DIV switch to .1 s.
(33) Ensure oscilloscope calibrator is set for a CHAN 1, MARKER mode output
of 10 ns/div.
(34) Adjust TI A and B TRIGGER LEVEL, B INTENSITY, and CH 1
⇕POSITION controls for suitable viewing.
(35) Adjust TI ⇐POSITION⇒ control to align 1st time marker that is 25 ns beyond
start of sweep with 2nd vertical graticule line.
(36) Rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton to
align 10th time marker with 10th vertical graticule line. Oscilloscope calibrator Err display
and TI linearity will be within limits specified in first row table 14.
(37) Repeat technique of (32) through (36) above for remaining TI settings and
oscilloscope calibrator outputs listed in table 14. Oscilloscope calibrator Err display and
TI linearity will be within limits specified in table 14.
b. Adjustments
(1) Position TI controls as listed in (a) through (c) below:
(a) HORIZONTAL MODE switch to A.
(b) A AND B SEC/DIV switches to .1 ms.
(c) X10 CAL control to in position.
(2) Set oscilloscope calibrator MARKER output to .1 mS/D.
