The R&S ESU is a new family of CISPR16-1-1-compliant EMI test receivers that meet all civil and military standards for electromagnetic interference measurements. The new FFT-based time-domain scan allows users to perform overview measurements up to 150 times faster than on previous EMI test receivers. The R&S ESU also features automatic and interactive measurement functions, realtime IF analysis and parallel detectors including the new CISPR-RMS detector.
