(24) Set A SWP SEC/DIV switch to 10 ns and B SWP SEC/DIV switch to 5 ns
(knob out).
(25) Press corresponding pushbuttons for indications as listed in (a) through (e) below.
TRIGGER SOURCE to VERT CH 1.
(a)
t to off (DLY readout).
(b)
A/B TRIG for B TRIGGER.
(c)
TRIGGER MODE to RUN AFT DLY.
(d)
XI0 MAG on.
(e)
(26) Set oscilloscope calibrator MARKER output initially for 10 nS/D.
(27) Set VOLTS/DIV switch as required for a display of 3 to 6 divisions and adjust
REF OR DLY POS control for DLY 10.64 ns.
(28) Adjust TRIGGER LEVEL control as required for a stable display.
(29) Adjust horizontal POSITION control cw until the trace stops moving, then ccw
to position leading edge of the 2d time marker near graticule center.
(30) Set oscilloscope calibrator MARKER output for 5 nS/D.
(31) Press t pushbutton to obtain t display and push SEC/DIV knob in for B SWP
only.
(32) Initially adjust control ccw until signal trace movement stops. Then adjust
control cw to superimpose the two time markers.
t indication will be within limits
specified in first row of table 15. If not, perform b below.
(33) Adjust control cw to move signal trace 2 signal peaks to left and superimpose
the signal trace (will be near 0.00 nSec on TI display). t indication will be within limits
specified in second row of table 15. If not, perform b below.
(34) Repeat technique of (33) above for remaining t readout indications listed in
19
