A microcomputer controlled apparatus and method for testing communication lines including circuits serving multiple functions in the measurements of line electrical and noise characteristics. A current divider, an analog to digital converter, a constant current source, various filters and an RMS-to-DC converter are used to perform A.C. and D.C. voltage and current measurements, resistance measurement and noise measurement. Capacitance measurement circuits and method utilize a buffer for isolating the capacitance on the wire measured from other capacitance sources.
