    transmitting a signal at a predetermined frequency and power level from the transmitter portion of the SAW interrogator;

    receiving the signal transmitted from the transmitter portion of the SAW interrogator by the independent receiver;

    measuring selected characteristics of the signal received by the independent receiver; and
