A SWEEP MODE switch to NORM TRIG.
(17) Position controls as listed in (a) through (d) below:
A AND B TIME/DIV AND DELAY TIME switches to .1 s.
(a)
HORIZ DISPLAY switch to DELAYED SWEEP (B).
(b)
Oscilloscope calibrator MARKER output to .1 s.
(c)
POSITION controls for second marker aligned with second vertical
(d)
graticule line.
(18) Set oscilloscope calibrator for a CHAN 1, MARKER output of .1 s. Rotate
oscilloscope calibrator knob located below EDIT FIELD pushbutton to align 1 marker per
division. Oscilloscope calibrator Err display readout will be within limits specified in first
row of table 6.
(19) Repeat technique of (17) and (18) above for TI and oscilloscope calibrator
MARKER output settings listed in table 6 for B sweep.
b. Adjustments
(1) Rotate oscilloscope calibrator knob located below EDIT FIELD pushbutton for
an Err display of 0.0%.
(2) Adjust C530A (fig. 5) for one marker per division on TI (R).
