(4) Disconnect oscilloscope from OUTPUT (+) and connect to OUTPUT (-).
(5) Repeat (2) and (3) above. If preshoot, overshoot, and ringing are not less than
5 percent of pulse amplitude, perform b(2) below.
b. Adjustments
(1) Adjust A6C25 and A6R25 (fig. 1) until preshoot, overshoot, and ringing is less
than 5 percent of pulse amplitude (R).
(2) Adjust A6C65 and A6R65 (fig. 1) until preshoot, overshoot, and ringing is less
than 5 percent of pulse amplitude (R).
12. Double Pulse
a. Performance Check
(1) Adjust PULSE PERIOD VERNIER control for a display of one complete
pulse on oscilloscope.
(2) Set PULSE DOUBLE/NORM switch to DOUBLE.
(3) Adjust PULSE DELAY VERNIER control to produce two pulses spaced at
least 20 ns between leading edges. If width of each pulse is not the same, perform b
below.
pulse (R).
13. Power Supply
NOTE
Do not perform power supply check if all other parameters
are within tolerance.
