(f)
(2) Connect oscilloscope calibrator to CH 1 input through 50 Ω termination.
(3) Set oscilloscope calibrator for MARKERS at 1 ms.
(4) Adjust horizontal POSITION control to align 1st time marker with 1st vertical
graticule line. Adjust INTENSITY control to view intensified 2d time marker.
(5) Press HORIZ DISPLAY pushbutton B DLY'D to on (in). If start of signal is

(8) Press HORIZ DISPLAY pushbutton B DLY'D to on (in). If start of signal is
not aligned with start of sweep trace, perform b (2) below.
(9) Press HORIZ DISPLAY pushbutton A to on (in) and set DELAY TIME
POSITION dial to full ccw.
(10) Adjust horizontal POSITION control to align 1st time marker with 1st vertical
graticule line. Adjust oscilloscope calibrator in EDIT mode for 1 marker per division. If
oscilloscope calibrator readout does not indicate within 2%, perform b (3) below.
(11) Press X10 MAG pushbutton to on (in).
(12) Set oscilloscope calibrator for MARKERS at .1 ms.

(17) Set B TIME/DIV control to 1 ms and press HORIZ DISPLAY pushbutton B
DLY'D to on (in).
(18) Repeat technique of (10) above.
If oscilloscope calibrator readout does not
indicate within 2%, perform b (5) below.
(19) Set oscilloscope calibrator for MARKERS at 5 μs.
(20) Position controls as listed in (a) through (e) below:
