(11) Set A SWP SEC /DIV switch to 5 ms and press X10 MAG pushbutton on.
(12) Change oscilloscope calibrator output to .5 mS/D.
(13) Adjust horizontal POSITION control to align 2d time marker with 2d vertical
graticule line.
(14) Rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton to
align 10th time marker with 10th vertical graticule line. If oscilloscope calibrator Err
display does not indicate within 1.95 percent, perform b below.
(15) Press X10 MAG pushbutton to off.
(16) Set A SWP SEC/DIV switch to 10 ns, and B SWP SEC/DIV switch to 5 ns and
push knob in for B SWP only.
(17) Set oscilloscope calibrator for a CHAN 1, MARKER mode output of 5 ns /div.
(18) Adjust TRIGGER LEVEL control for a stable display.
(19) Adjust horizontal POSITION control to align 2d time marker with 2d vertical
graticule line.
(20) Rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton to
align 10th time marker with 10th vertical graticule line. If oscilloscope calibrator Err
display does not indicate within limits specified in first row of table 9, perform b below.
(21) Repeat technique of (16) through (20) 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 below.
