the spectrum analyzer completes each sweep, a series of
approximately 18 new responses should be displayed, as shown
in Figure 3-92. The peaks of these responses coarsely outline the
spectrum analyzer frequency response.

35. Gradually readjust (Band A Lower Segment) A6AllR48 Al and
(Band A Upper Segment) A6AllR66 A2 for maximum flatness of
the displayed signal responses. The adjustments are interactive,
with A6AllR48 Al having the most effect on the level of the
displayed signals below approximately 500 MHz (the marker
position), and A6AllR66 A2 having the
of the displayed signals above approximately 500 MHz. Adjust
displayed signal responses below 500 MHz. Adjust A6AllR66 A2
