Abstract

A method and apparatus for detecting a fault in a transceiver. A microprocessor reads a predetermined first minimum value and a predetermined first maximum value of received input signal levels, and converts the measured instantaneous AGC control voltage into a received input signal level. When the converted received input signal level is below the predetermined first minimum value or above the predetermined first maximum value, the microprocessor determines that a fault exists in the amplifier operation of the down converter. On the other hand, the microprocessor reads a predetermined second minimum value and a predetermined second maximum value of IF detection voltage values, and also reads an instantaneous IF detection voltage, which is measured by the AGC. When the instantaneous IF detection voltage is below the predetermined second minimum value or above the predetermined second maximum value, the microprocessor determines that a fault exists in the AGC operation of the down converter.

Description

[0001] This application claims as early as June 15, 1998 at the Korean Industrial Property Office, the serial number is No. 1998-22291, and the title is "Method and device for fault diagnosis of transceivers in base stations (AMETHOD AND AN APPARATUS FOR FAULT DIAGNOSTIC OFTRANSCEIVER IN BASE STATION)", which is hereby incorporated by reference. technical field [0002] The invention relates to a self-diagnostic system for detecting faults in a transceiver in a radio receiving unit of a base transceiver station. More particularly, the present invention relates to a self-diagnosing method and apparatus for diagnosing and detecting internal circuit failures of a transceiver unit in a radio base transceiver system (BTS). Background technique [0003] In the mobile communication system, that is, in the traditional code division multiple access (CDMA) system, the system is equipped with multiple mobile stations (MS), multiple base transceiver systems (BTS) that provide services f...
