The R&S ESR3 is an EMI test receiver for the frequency range from 10 Hz to 3.6 GHz and complies with the CISPR 16-1-1 standard. It measures electromagnetic disturbances with the conventional stepped frequency scan or – at an extremely high speed – with an FFT-based time domain scan. At the same time, it functions as a full-featured, powerful signal and spectrum analyzer for lab applications. Featuring realtime spectrum analysis capability with a wide range of diagnostic tools, the test receiver also enables detailed analysis of disturbance signals and their history. This instrument comes with clearly structured menus and an intuitive touchscreen, making it very easy to operate in any mode.

The R&S ESR measures up to 6000 times faster than conventional EMI test receivers. Disturbance measurements that took hours in the past can now be completed in just seconds. This also applies to measurements across wide frequency ranges or with small step sizes as well as to disturbance voltage measurements using quasi-peak and average weighting. This saves considerable time and cost during product development and certification. Besides offering functionality for EMC conformance testing, the unit features real-time spectrum analysis capability, providing new diagnostic tools such as a spectrogram, persistence mode and frequency mask trigger. With these tools, users can detect hidden or sporadic emissions and analyze their causes. The clearly structured menus combined with the intuitive touchscreen make the test receiver very easy to operate in any mode. It displays up to six different traces on the large, 21 cm (8.4”) touchscreen for fast, effective result analysis. Compact dimensions, low weight, optional ruggedized housing and optional DC power supply make the R&S instrument an ideal choice also for mobile applications.
