Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing.

[0022] see figure 1 , the signal source and spectrum analyzer used in the specific implementation examples are: Agilent4438C and Agilent4445. The hardware environment for automatic detection of GSM dry amplifier is composed of test workstation, signal source, spectrum analyzer, attenuator, RF matrix switch and GSM dry amplifier under test.

[0023] The test workstation controls the signal source and the spectrum analyzer through the GPIB bus. GPIB bus protocol adopts IEEE 488 standard. Various remote control SCPI (Standard Commands for Programmable Instruments) commands can be obtained by consulting the user manuals of the signal generator and the spectrum analyzer.

[0024] The test workstation controls the RF matrix switch through the RS485 bus. The RF matrix switch can automatically switch the RF path during uplink test and downlink test. The protocol on the RS485 b...

Abstract

The invention relates to an automatic detection method aiming at GSM trunk amplifying. The GSM trunk amplifying automatic detection system is composed of a test workstation, a supply oscillator, a frequency spectrograph, an attenuator, a radio frequency matrix switch and a tested GSM trunk amplifying, wherein, the test workstation controls the supply oscillator and the frequency spectrograph by aGPIB bus, controls the radio frequency matrix switch by a RS485 bus and connects the monitoring interface of the tested GSM trunk amplifying by a RS232 interface; the radio frequency matrix switch can automatically switch radio frequency accesses when in uplink testing and downlink testing; a gain test, an automatic level control test, a digital attenuation test, an in-band wave test, an intermodulation test and a real-time monitoring data check can be finished by the GSM trunk amplifying automatic detection system. The automatic detection method of the invention replaces artificial cockamamie test, shortens the production test time of the GSM trunk amplifying, improves the productivity and efficiency of enterprises, meanwhile, the quality is stable and the test results are not affected by anthropogenic factors.

Description

technical field [0001] The invention relates to an automatic test technology in GSM communication, in particular to an automatic test method for a GSM trunk line amplifier (dry amplifier for short). Background technique [0002] Trunk amplifier, referred to as dry amplifier, is a signal amplification device when the power becomes low and cannot meet the coverage requirements. When the power of the signal source device is difficult to meet the coverage requirement, the device can amplify the power of the signal source (usually a microcell) to cover more areas. [0003] GSM dry amplifier belongs to the same frequency amplification equipment, which is used to realize GSM network coverage. [0004] In the production of GSM dry storage, if its performance technical indicators are strictly tested according to the current manual testing method, the operation is complicated, the efficiency is low, the speed is slow, and the testing quality is affected by human factors.
