Abstract:
1. A test method for determining radiated radio frequency (RF) receiver sensitivity defined based upon a traffic channel (TCH) power level at a desired bit error rate (BER) for a plurality of channels extending over at least one frequency band using an RF source coupled to an RF receiver by a wireless RF communications link, the test method comprising: determining a BER versus TCH power level function for an initial channel; determining an estimated TCH power level for a subsequent channel based upon the BER versus TCH power level function and the desired BER; measuring a BER of the subsequent channel based upon the estimated TCH power level; comparing the measured BER to the desired BER and using a difference therebetween along with the BER versus TCH power level function to determine a next estimated TCH power level; and repeating measuring and comparing if the difference is greater than a threshold to thereby determine a TCH power level in the subsequent channel corresponding to the desired BER.
