(7) Repeat technique of (3) through (6) above for remaining TI settings and
oscilloscope calibrator outputs listed in table 9. If oscilloscope calibrator Err display and TI
linearity are not within limits specified in table 9, perform b (1) through (10) below.

(8) Pull TI A AND B SEC/DIV CAL knob out for X10 sweep magnification.
(9) Set oscilloscope calibrator for a CHAN 1, MARKER mode output of 10 ns/div.
(10) Set TI A AND B SEC/DIV to .05 s.
(11) Adjust TI A TRIGGER LEVEL, A INTENSITY, and CH 1 ⇕POSITION
controls for suitable viewing.
(12) Adjust TI ⇐POSITION⇒ control to align 1st time marker that is 25 ns beyond
start of sweep with 2nd vertical graticule line.
(13) Rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton to
and TI linearity are not within limits specified in table 10, perform b (11) through (17)
below.
