Automotive EMI standards are developing quickly to address the impact of electric and hybrid vehicles on the electromagnetic environment. Recent changes in CISPR 25 & CISPR 36 and the ongoing revision of CISPR 12 as well as a demand to reduce test time and record the disturbance characteristic of the device under test bring new requirements for vehicle manufacturers and component suppliers. Usage of FFT-based measuring instruments is the key for addressing these topics. The presentation will address the applicability of FFT-based receivers for EMI compliance measurements against international standards, gives an inside view on the technology of such receivers and will conclude with practical use cases.
