Design and Implementation of a Multi-module Integrated Automatic Test System
With the rapid increase of multi-module integration testing requirements,the traditional single test envi-ronment can not meet the requirements of highly integrated and tightly coupled product testing.In this paper,an au-tomatic test system is designed for the power module and switch matrix module of the RF integrated processing u-nit.It is programmed through the mixed topology structure composed of GPIB/LAN bus,and is equipped with spe-cial test fixture and CAN/MLVDS interface card to automatically collect module signals.Rf switching channel and KVM switch are used to control multiple modules.Information transfer and index test were carried out.The results show that the test efficiency is greatly improved by means of fault isolation at module component level.
