Description

technical field [0001] The invention belongs to the technical field of electromagnetic measurement. Background technique [0002] With the development of science and technology, the complexity of weapon systems is getting higher and higher. In order to meet the support requirements of modern weapon systems in the process of development, design, production and maintenance, a large number of military automatic test systems (ATS) are used as the corresponding detection. The means of maintenance provide the necessary guarantee for the reliable operation of the weapon system, and the performance indicators of the system must be guaranteed by metrological calibration. [0003] Since military test equipment mostly adopts automatic test and control technology, in the measurement and calibration of electrical parameters, the following two calibration methods and methods are generally used at present: [0004] (1) Decentralized general measurement standard [0005] Using general mea...

Problems solved by technology

[0011] The measurement verification system established by using program-controlled instruments can realize automatic measurement verification and high verification efficiency, but there is no unified standard and design framework, no flexible design for measurement objects, and it is impossible to allocate measurement resources on demand. The redundancy and waste of measurement resources is serious. The cost of bidding is high, the technical support is not strong, and the modularization, generalization and serialization of the measurement guarantee equipment have not been realized, and it is not conducive to the front-end measurement guarantee
