The present invention relates to a system for operating an automatic test equipment through modularization, and more particularly, to an open platform of an automated test equipment (ATE) system, The present invention relates to a system for operating an automatic test equipment through modularization capable of flexibly responding.

Conventional ATE (Automated Test Equipment) system automatically tests the function and performance of electronic equipment composed of various types of circuit assemblies with minimum operator intervention, and identifies the faulty item among the internal components. This conventional automatic test equipment requires modification to the entire automatic test equipment software that is not related to the instrument when the instrument is changed according to the breakdown or discontinuance of the instrument. Therefore, it is inevitable that the time cost is wasted. .

In the case of automatic test equipment which has already been developed and operated, it is necessary to modify the software of the entire automatic test equipment when the test target equipment is added, and to add / delete the function even if development to the specific test equipment is required Since it is almost impossible, the development cost of the automatic test equipment is continuously generated.

In other words, the existing automatic test equipment is added to the test equipment (UUT, Unit Under Test) or the electronic equipment during operation after the initial development, or the test equipment ) Has a fairly closed structure.

Due to this closed structure, hardware / software dependency is high, and there are significant restrictions on maintenance and operability.

The automatic test equipment operation system through the modularization of the present invention can be realized by modularizing the software itself for operating the automatic test equipment so that it is possible to change the software corresponding to the test equipment addition, Only software can be replaced, minimizing or eliminating device dependencies between hardware / software.

In this connection, Korean Patent Registration No. 10-0164836 ("Radio Equipment Automatic Test Apparatus and Method") discloses an automatic test apparatus for automatically testing a module of a radio equipment to diagnose a failure.
