Abstract
A method for determining failure modes of a transceiver (,) includes applying a control signal (,) to a transmitter (,) of transceiver (,). The power level of a transmit signal (,) is proportional to a predetermined voltage level of control signal (,), and is detected by a detector (,) which correspondingly produces a transmit power level indicator (,). A portion of transmit signal (,) is coupled to produce a coupled transmit signal (,) which is received by a receiver (,) of transceiver (,). Receiver (,) produces a receive signal strength indicator (,) corresponding to the power level of coupled transmit signal (,). Voltage levels of received signal strength indicator (,), transmit power level indicator (,) and predetermined voltage level of control signal (,) are stored in a memory means,and compared in a controller,to determine failure modes of receiver (,) and transmitter (,).
