6. In the software window, set the VCO center frequency
(Figure 19 shows a screenshot of the signal source analyzer
operating in phase noise mode, taken at a carrier frequency
of 1750 MHz). Set the proper PFD frequency to 25 MHz,
and program the reference frequency to equal 25 MHz.
The charge pump current should equal 2.5 mA. See
Figure 20 for the suggested setup.
