A test method is described for determining radiated radio frequency (RF) receiver sensitivity may include determining a bit error rate (BER) versus traffic channel (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 a desired BER, and measuring a BER of a subsequent channel based upon the estimated TCH power level. The method may further include 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.
