摘要
Purpose: by measuring the intensity in a Background Noise Power of a receiver board, the method in Rx path of the one kind for checking PCS (PCS Personal Communications System) BTS (base station transceiver subsystem) using background noise is arranged to the state in the paths Rx, does not use the necessity of a BTU (BTS experimental rigs). Construction: the intensity for flowing to a background noise of an antenna front ends unit becomes -113 decibel meter/1.23 megahertzs (s1). The intensity of background noise is that the D decibels of amplification pass through antenna front ends unit (s2). If the grade value of a received signal strength indicator is less than -113+D decibel meters (s3), (s5) alarm is generated, consideration generates abnormality on the paths Rx (s4). If not (s3), determining that the paths Rx are normal (s6).
