CIRCUIT FOR TESTING BASE STATION IN MOBILE COMMUNICATION SYSTEM

摘要

A test circuit of a base station for use of a mobile radio communication system includes a terminal simulator for analyzing radio frequency signals provided from the base station and outputting the analyzed signals to an exam controller; a radio frequency signal path adjuster connected to the terminal simulator, for adjusting a combination and division of radio frequency signals, and a selection of a test path and a level of signals; and the exam controller connected with the radio frequency signal path adjuster, the terminal simulator and an upper level controller, the exam controller being for operating according to a test instruction of the upper level controller or controlling the radio frequency signal path adjuster and the terminal simulator to thereby execute a test and inform the upper level controller of the test result; whereby enabling the test circuit to be performed in a mutual test between sectors of the base station and an unmanned automation test.
