BASE STATION TEST APPARATUS OF MOBILE COMMUNICATION SYSTEM USING MULTIPLE FREQUENCY ALLOCATION

摘要

PURPOSE: A base station test apparatus of a mobile communication system using a multiple frequency allocation is provided to diagnose and maintain a base station by remotely measuring transmission and reception output from a base station for single or multiple frequency allocation and monitoring a spectrum. CONSTITUTION: Transmission and reception path disconnecting units(811-820,842-846) are connected to at least two antennas and disconnect a transmission and reception path to a base station. A transmission unit transmits a signal to the base station through the transmission path disconnecting unit(811-820). A reception unit receives the signal from the base station through the reception path disconnecting unit(842-846). A power measurement unit detects the signal transferred through an intermediary frequency path disconnecting unit. An RF spectrum monitoring assembly samples the intermediary frequency signal and then displays the same in the form of an RF spectrum.
