Fig. 6-18. Test setup for step 15.
15. Check Aberrations
a. Remove the current loop and probe from the square­
wave generator and connect to pulse generator output. Con­
nect the delay cable to the pulse generator charge line con­
nectors, using the two lengths of RG-8A/U. See Fig. 6-18.
b. Set pulse generator Voltage Range to 5.0, Pulse Polarity
to — , and turn power on. Set test oscilloscope Volts/cm to
.2 volt, Time/cm to .2 µs and turn X10 Mag on.
c. Adjust pulse generator Amplitude and test oscillocope
Trig Level Io obtain a 4-centimeter display. (Use the viewing
hood if necessary).
d. Check aberrations for <3%, peak to peak.
e.
Remove the probe from the pulse generator and place
in the holder. Turn X10 Mag off.
