(57) Change oscilloscope calibrator MARKER mode output to 50 nS/D.
(58) Adjust ΔREF OR DLY POS control for DLY 53.2 ns and horizontal
POSITION control to position leading edge of 2d time marker near graticule center.
(59) Position calibration generator controls for 5 nS/D output.
(60) Press Δt pushbutton to obtain a Δt display and push in SEC/DIV knob for B
SWP only.
(61) Adjust Δ control for a Δt readout indication near -50.0 ns to superimpose the two
time markers. If Δt readout indication is not between -49.30 ns and -50.70 ns with the two
time markers superimposed, perform b below.
(62) Adjust Δ control for a Δt readout indication near 50.00 ns to superimpose the
two time markers. If Δt readout indication is not between 49.30 ns and 50.70 ns with the
two time markers superimposed, perform b below.
(63) Adjust Δ control for a Δt readout indication near 400.00 ns to superimpose the
two time markers. If Δt 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 μS/D.
(68) Press Δt pushbutton on and adjust Δ and ΔREF
DLY POS controls for a Δt
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 ΔREF 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 μS/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).
