On the basis of in-depth analysis of operating principle and structure of the host machine, this paper confirms test tasks and process, according to the signal features for the index design and test function circuit, completes the test of the host machine PXI-2204 data acquisition card's AD test, DA test, DI/O test, counting test, RS232 serial test, warning lights voltage test, image acquisition card RTV-24 test. In practice, the design of interface, appearance and set-up inside for the adapter is completed. LabWindows/CVI is used for program development. The virtual instrument technology is used to finish the test function interface, which provides a good human-machine interaction environment. Finally through collecting with the host machine, this paper verifies the effectiveness of self-test adapter.
