b. Adjustments
(1) Set oscilloscope calibrator for a 50 ns MARKER output and adjust C330 50 ns
TIMING (fig. 1) for one time marker per division between second and 10th vertical graticule
line (R).
(2) Set oscilloscope calibrator for a 10 s MARKER output and adjust R710 10 s
TIMING (fig. 1) for one time marker per division between second and 10th vertical graticule
line (R).
(3) Set oscilloscope calibrator for a 10 ms MARKER output and adjust R715 10 ms
TIMING (fig. 1) for 1 time marker per division between second and 10th vertical graticule
line (R).
10. Delay Offset and Gain
a. Performance Check
(1) Press MAG to (X1) in, B DELAY MODE B STARTS AFTER DELAY and
oscilloscope HORIZONTAL MODE ALT pushbuttons.
(2) Set B time base unit TIME/DIV switch to 10 s and TI TIME/DIV switch to 1 ms.
