Phase Lock Loop Bandwidth vs. Peak Tuning Range
The graph in Figure 297 illustrates the closed Phase Lock Loop Bandwidth
(PLL BW) chosen by the test system as a function of the Peak Tuning Range of
the source. Knowing the approximate closed PLL BW allows you to verify that
there is sufficient bandwidth on the tuning port and that sufficient source
isolation is present to prevent injection locking.
