Abstract
A base station timing analyzer measures the timing performance of a base station from within the base station coverage area without interruption or degradation of the system performance. The timing analyzer has a dummy signal generation mechanism that produces a dummy signal output based on a universal time input. An antenna couples a signal from an operating base station from a wireless link. A summer sums together the dummy signal and signal from the wireless link. A demodulation element receives the summed signal and searches for and demodulates each of the signals. A comparison unit compares the output of the demodulation element to determine the timing performance of the base station to provide an indication of the absolute time offset of the base station signal.
