Device and method for measuring receive sensitivity of communication system including receive-only path

摘要

Disclosed is a device ( 200 ) and a method for measuring a receive sensitivity of a communication system having a transmit and receive path and a receive-only path, like a base station ( 100 ) employing space diversity by means of one transmit and receive antenna ( 111 ) and an additional receive antenna ( 121 ). A terminal ( 220 ) is connected to the transmit and receive path and to the receive-only path by means of a first ( 112 ) and a second coupler ( 122 ) and a first ( 213 a) and a second transmitter ( 215 a) whereby the input signals are combined by a combiner ( 211 ) to a single signal fed to the terminal ( 220 ). Furthermore, the terminal ( 220 ) selectively transmits a test signal at selected frequencies to a receive sensitivity measuring path by means of a first ( 212 ) and a second ( 214 ) switch and a first ( 213 b) and a second ( 215 b) receiver in order to measure the receive sensitivities of the transmit and receive path and the receive-only path of the communication system and to measure the performance of the corresponding communication system.
