R&S ESU EMI Test Receiver

The R&S ESU from Rohde & Schwarz is a new family of CISPR16-1-1-compliant EMI test receivers that meet all civil and military standards for electromagnetic interference measurements. New FFT-based test methods speed up the measurement. With the time-domain scan, users can perform overview measurements up to 100 faster than on previous EMI test receivers. The instrument also features comprehensive test functions such as a complete set of parallel detectors including the new CISPR-RMS detector, RF scan, IF analysis and numerous report functions. The R&S ESU is available in three models with the frequency ranges 20 Hz to 8 GHz, 26.5 GHz and 40 GHz.
