| 摘要 |
The present invention relates to a base station (BTS) of a radio system comprising several receivers (RX1, RX2) and several transmitters (TX1, TX2), whereby at least one of the receivers comprises means for measuring the signal level of the received signal. In order to measure disturbances caused by intermodulation of signals of the transmitters the base station comprises testing means (3). The transmitters (TX1, TX2) are responsive to said testing means (3) for generating predetermined signals to the antenna means (1, 2). Furthermore, said receiver (RX1) is responsive to the testing means (3) for receiving signals from frequency channels (f3, f4) of the base station normally in reception use and measuring the signal level of the received signal. |
