Abstract:
1. A testing device for testing a transceiver, said testing device comprising: a transmitter operable in a first state to transmit signals; a receiver operable in a second state to receive signals; a power coupler coupling said transmitter to said receiver; an overload protection device operably coupled between said power coupler and said receiver to reduce the signal strength of a received signal at said receiver based on a control signal; and a controller operable to determine a current state of said received signal and to generate said control signal based on said current state of said received signal, wherein said controller includes a comparator for comparing a signal level of said received signal to a threshold, and wherein said controller is operable to generate said control signal to reduce the signal strength of said received signal when said signal level is greater than said threshold and to generate said control signal to restore the signal strength of said received signal when said signal level is less than said threshold.
