to a positive or negative
number b/4 to set the frequency. T=0 is the default setting for 24.125GHz. Each increment steps
approximately 18MHz. The programming steps are limited to 24.089 through 24.161GHz operation.
Depending on the spread between the current frequency and the newly set frequency, there may be a
long settling time on the order of 5-10 seconds or longer based on the size of the jump in values. Writing
