Making the Initial Carrier Frequency Tolerance
Measurement

Purpose

The initial carrier frequency tolerance measurement is designed to verify the
accuracy of the transmitter's initial carrier frequency.

Measurement Method

This is measured by integrating over the frequency deviations of the packets first 4
bits (the preamble bits). The result is either a positive or negative number in Hz
indicating the frequency difference from the specified nominal carrier frequency.
This measurement requires the signal to be demodulated to measure the frequency
deviation of each symbol. After demodulation, the frequency offset of each of the
preamble bits is measured and averaged.
