Figure 8. Pulse modulated display.
(7) Verify pulse overshoot and undershoot is less than 20 percent and ALC
UNLEVEL light on TI is extinguished. If signal is not within limits specified perform
adjustments listed in b below.
(8) Set TI, and synthesized signal generator to the remaining frequencies and levels
listed in table 14, and repeat (7) above at each frequency.
