Patent ID: 7327984

Claim:
A receive sensitivity measuring device including a terminal for transmitting a test signal through a receive sensitivity measuring path so as to measure the receive sensitivity of a communication system including (1) a transmit-and-receive path operatively connected to both a base station transmitter and a base station primary receiver, and (2) a receive-only path connected to a base station diversity receiver, a the receive sensitivity measuring device coupled to the receive-only path and the transmit-and-receive path, the receive sensitivity measuring device comprising: a first transmitter ( 213 a ) for receiving a first signal from the transmit-and-receive path, and transmitting the first signal to the terminal; a second transmitter ( 215 a ) for receiving a second signal from the receive-only path, and transmitting the second signal to the terminal; a first receiver ( 213 a ) for receiving the test signal from the terminal, and transmitting the test signal to the transmit-and-receive path; a second receiver ( 215 b ) for receiving the test signal from the terminal, and transmitting the test signal to the receive-only path; a signal selector ( 212 or 214 ), for selecting one of the first or second receivers connected to the signal selector and the receive sensitivity measuring path so that one of the first or second receivers is selectively connected to the terminal; and a combiner ( 211 ), connected to the first and second transmitters ( 213 a and 215 a ) and the first and second receivers ( 213 b , 215 b ), for combining the first signal and the second signal into a single signal, and transmitting the single signal to the terminal, wherein the terminal transmits the test signal to the receive sensitivity measuring path so that the corresponding receive sensitivity measuring path measures a cable loss to the terminal and the receive sensitivity generated by using the test signal transmitted by the terminal.
