CAUTION
In Step o, the beam current may decrease as the attenuator is pulled out.
Should this occur, lock the attenuator all the way in, and adjust A4R1.
Turn A4R1 maximum ccw, then cw until the de voltmeter indicates a peak (see figure 5-10a).
Continue turning A4R1 cw. The de voltmeter indication will remain the same, or decrease, then increase again
to the peak level of step o. This double peaking indicates saturation.
NOTE
If the "saturated ” double peak is not evident in steps p and q, pull A4
attenuator out slightly and repeat steps p and q (see Figure 5-10a). If saturation
cannot be attained with the attenuator pulled out all the way, realign A4
Harmonic Generator as described previously.
If A4R1 is turned further cw, the de voltmeter indication will decrease, then increase
amplitude than in step o.
Tkt rnrrprt neak is the first one encountered as R1 is turned cwfrom its maximum ccw position. Reset A4R1 by
burning R full ccw and then cw to the first peak. This completes Harmonic Generator A4 alignment.
