Description

technical field [0001] The invention relates to an automatic test interface conversion device for electronic products, in particular to a universal bus interface conversion and data preprocessor for realizing automatic test control. Background technique [0002] At present, when users test radio frequency microwave and power electronic products, usually one interface bus corresponds to one board or test device, although the general measurement and control bus can be used to centrally control various mainstream test instruments or equipment (such as PXI, PCI, etc.), however, when the object under test requires multi-bus hybrid communication, the expansion of this measurement and control platform architecture is often not flexible enough, and different hardware drivers need to be added and reprogrammed, which often changes the test platform structure. Continuously increase the workload of test application software development and increase the difficulty and complexity of autom...
