Web-service based framework for testing automatic amplitude-frequency characteristic of filter

Web-service is applied in setting up a three-layer framework for automatic amplitude-frequency characteristic test of splitters which is introduced in this paper. Key technologies are studied to implement the system framework. It combines the technologies of embedded test instrument and web access, utilizing test agents distributed in different production lines as basic service providers. Additional to UDDI registration mechanism, active service availability polling mechanism (ASAP) is implemented to make sure the service available. The framework has advantages of flexible arrangement, high test efficiency, high utilization of detected result and easy to inquire.
