Rohde & Schwarz ESR EMI test receiver

The Rohde & Schwarz ESR test receiver is available in two different models for frequencies ranging from 10 Hz to 3 GHz or 7 GHz to meet the requirements of all users who perform EMC certification on commercial equipment. It covers all commercial standards relevant for test houses and EMC labs used by electrical equipment manufacturers and their suppliers.

The test receiver features time domain scan, an FFT-based receiver technology that allows it to perform measurements which previously took hours in just a few seconds. This measurement method offers great advantages when the DUT can only be operated for short periods for testing, eg, in the automotive and lighting industry.

The Rohde & Schwarz ESR has a number of analysis capabilities. The spectrogram function displays the analysed spectrum over time and records measurements for up to 5 h, allowing developers to detect sporadic interferers. The frequency mask trigger responds to specific events in a spectrum. If the mask is violated, a trigger is activated. The measurement is stopped, and the user can analyse the exact cause and effect of the interferer. The persistence mode allows users to clearly differentiate between pulse interferers and continuous interference. It displays the probability distribution of occurring frequencies and amplitudes in various colours, making it possible to detect interferers that are hidden by broadband signals.

The test receiver is also a full-featured spectrum analyser and offers proven tools such as IF analysis and time domain display, while conventional stepped frequency scans allows comparison with previous results. The clearly structured touch screen distinctly separates the various measurement modes and the operating mode can be switched at the press of a button. Users can easily configure measurements and automated test sequences directly on the touch screen. The R&S EMC32 software can be used to remotely control the R&S ESR and integrate it into complex EMC systems for automated measurement sequences.

The R&S ESR makes it easy to perform acceptance testing (conducted or radiated) in line with EN/CISPR/FCC on modules, assemblies, household appliances, IT equipment, TVs, radios, etc. In the automotive sector, the R&S ESR is suitable for acceptance testing of vehicles and accessories in line with automobile manufacturer guidelines, also for mobile applications thanks to the DC operation option.
