bit
The 12-bit parameter of the Frequency Setting Command <f11- f0> has the value F. The value F should
be in the range of 96 and 3903. When F is out of range, the previous value is kept. The synthesizer center
frequency f0 can be calculated as:
f0 = 10 MHz * C1 * (C2 + F/4000)
The constants C1 and C2 are determined by the selected band as:
