(57) Change oscilloscope calibrator MARKER mode output to 50 nS/D.
(58) Adjust ∆REF OR DLY POS control for DLY 53.2 ns and horizontal
POSITION control to position leading edge of 2d time marker near graticule center.
(60) Press ∆t pushbutton to obtain a ∆t display and push in SEC/DIV knob for B
SWP only.
(61) Adjust ∆ control for a ∆t readout indication near -50.0 ns to superimpose the two
time markers. If ∆t readout indication is not between -49.30 ns and -50.70 ns with the two
time markers superimposed, perform b below.
(62) Adjust ∆ control for a ∆t readout indication near 50.00 ns to superimpose the
two time markers. If ∆t readout indication is not between 49.30 ns and 50.70 ns with the
two time markers superimposed, perform b below.
(63) Adjust ∆ control for a ∆t readout indication near 400.00 ns to superimpose the
two time markers. If ∆t readout indication is not between 398.30 ns and 401.70 ns with
the two time markers superimposed, perform b below.
(64) Press TRACK/INDEP pushbutton for TRACK.
(65) Press X10 MAG pushbutton to off. Set A SWP SEC/DIV switch to 100 ns and
B SWP SEC/DIV switch to 10 ns (knob out).
(66) Press X10 MAG switch on.
(67) Change oscilloscope calibrator MARKER mode output to .1 S/D.
DLY POS controls for a ∆t
(68) Press ∆t pushbutton on and adjust ∆ and ∆REF
OR
readout of (eight times A SWP SEC/DIV setting) 800.0 ns.
(69) Adjust horizontal POSITION control to align leading edge of 2d time marker on
A sweep with 2d vertical graticule line.
(70) Adjust TRACE SEP control ccw to separate traces.
(71) Adjust ∆REF OR DLY POS control to intensify 2d and 10th time markers of A
sweep and display leading edges of displayed B sweep time markers near center
graticule line.
(72) If horizontal distance between leading edges of B sweep time markers is not 3.4
divisions or less, perform b below.
(73) Press X10 MAG pushbutton to off.
(74) Set A SWP SEC/DIV switch to 200 ns and set B SWP SEC/DIV switch to
20 ns (knob out).
(75) Press Xl0 MAG pushbutton on.
(76) Change oscilloscope calibrator MARKER mode output to .2 S/D.
(77) Repeat technique of (68) through (72) above.
(78) Press Xl0 MAG pushbutton to off.
(79) Set A SWP SEC/DIV switch to 500 ns and set B SWP SEC/DIV switch to 5 ns
(knob out).
