Problems solved by technology

This method not only has great damage to the equipment and low efficiency, but also due to the influence of the system environment, the technical index of a single instrument cannot represent the whole system. Therefore, the metrological verification results obtained by this method are not accurate.

Abstract

The invention provides a metrological verification device capable of realizing in-situ integral metrological verification for an automatic test system based on a GPIB (general purpose interface bus) and VXI (virtual extension interface) mixed bus, which comprises a control computer, a standard instrument and a verification adapter, wherein the standard instrument is connected with the verification adapter through a cable and is connected with the control computer through a GPIB control bus, a GPIB controller, a VXI-MXI (multisystem extension interface) controller and a metrological verification program are installed in the control computer of the automatic test system, and the verification adapter is connected with an ARINC608A interface of the automatic test system. When metrological verification is performed, measurement data are obtained from the ARINC608A interface of the automatic test system, in-situ metrological verification of the automatic test system is realized, damage to instruments and equipment is reduced, integral verification of comprehensive technical indexes of the ATS (automatic test system) is realized, and verification efficiency is improved.

Description

technical field [0001] The invention relates to the metrological verification of an automatic test system, in particular to a metrological verification of an automatic test system based on a GPIB and VXI hybrid bus. Background technique [0002] With the development of automatic test technology, more and more application integrated and automated automatic test systems (Automatic Test System, ATS for short) are tested. ATS is controlled by a control computer through GPIB, VXI and other buses. It has the characteristics of many types of instruments and equipment, wide distribution of parameters, complex interface technology, and many sources that affect the measurement results. At present, my country has not promulgated corresponding metrological verification regulations for the metrological verification of ATS. In actual work, the method of off-site measurement is generally used, that is, a single instrument is removed and sent to the laboratory for metrological verification....
