Abstract :
A measurement system of dynamic resistance of vehicle electronic line connector based on PXI Express(PXIe) technology was established. The system hardware was composed of PXIe box, PXIe high speed digitalizer, PXIe arbitrary waveform generator, high precision currency source and so forth. And the system operating interface was designed by LabVIEW, the virtual instrumentation software, with direct test results displayed on screen. This system can automatically measure dynamic impedance avoiding leaking the unqualified data which lead to imprecise test, and it can meet with the automotive manufactory and supplier real-time monitor requirement. Measurement result shows the maximum sampling rate is 100 million per second and can record at least 3 hours.
