Ext Ref In
This field selects the reference frequency of the signal at the EXT REF
IN connector. You can select 1, 2, 5, or 10 MHz; 1x, 2x, 4x, 8x, or 16x
chip.
Operating Considerations
This signal is used as a reference for, and directly affects, these
functions:
RF Generator Frequency (including the Tracking Generator)
RF Frequency Counter
AF Frequency Counter

Spectrum Analyzer Center Frequency
AF generators 1 and 2 are not affected by the external reference; they
use their own reference.
