Design of electrical five-parameter calibration source based on PXI bus

Abstract Aiming at the problems of a large volume of current electrical five-parameter standard source devices, inconvenience in carrying them to the test site, and difficulty in conducting automatic metrology tests, a PXI board-type electrical five-parameter calibration source device is designed. Together with the driver control and automatic test software, workers can complete the on-site automated verification and calibration of electrical parameter test equipment in automatic test systems and related equipment tests by using the on-site PXI chassis, without the need to carry chassis and desktop devices or disassemble the devices to be tested, which greatly improves work efficiency and realizes portable, channel-expandable, and integrated automatic calibration.
