A transceiver (203) instructs a RF switch matrix (200) to direct its output to any one of M outputs and likewise sends information related to the power and frequency of the RF input signal and the switched output to an OMC (112). Each output of the matrix (200) is adjusted by an attenuator bank (218) and fed to a spectrum analyzer (233). OMC (112) relays the power, frequency and switched output information to a computer (239) which instructs the spectrum analyzer (233) to perform a power measurement at the frequency of the RF input signal. The computer (239) then determines which outputs of the matrix (200) were switched based on the power level of the RF input signal, the measured power level of the adjusted output signal and a relationship of the different predetermined levels within attenuator bank (218) and verifies by comparison to the switched output information.
