A ONLY
(20) Repeat technique of (17) through (19) for remaining TI settings and oscilloscope
calibrator output settings listed in table 12. Oscilloscope calibrator err display and TI
linearity will be within limits listed in table 12; if not, perform adjustments listed in
(21) Set X10 CAL control to out position.
(22) Set TI A AND B SEC/DIV switches and oscilloscope calibrator output as listed
in table 13.
(23) Adjust A AND B TRIGGER LEVEL, B INTENSITY, and CH 1 POSITION
controls for suitable viewing.
(24) Adjust horizontal POSITION control to aline the 1st time marker that is 25 ns
beyond start of sweep with the 2d vertical graticule line.
(25) Rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton to
and TI linearity will be within limits listed in table 13; if not, perform adjustments listed in
