The R&S ESW EMI test receiver from Rohde & Schwarz is designed for applications in manufacturers’ EMI labs and in test houses.

It can carry out certification tests on modules, components and devices as well as on systems and technical facilities in line with all relevant commercial and military standards such as CISPR and FCC. The receiver is suitable for conducted as well as radiated certification measurements, and even meets the stringent demands placed on EMI measurements in the automotive sector, stipulated by internal company standards.

The product is available in three versions for the frequency ranges from 2 Hz to 8 GHz, -26 GHz and -44 GHz. The instrument includes as standard a very fast FFT-based time domain scan (TD scan), which reduces the time required for standard-compliant certification tests. The TD scan can also be run with two CISPR detectors to carry out parallel measurements.

For diagnostics and troubleshooting, users can use additional operating modes such as sweep, scan, real-time spectrum analysis and IF analysis, each with a spectrogram function. The spectrogram function seamlessly displays the analysed spectrum versus time, making even rapidly changing interferers visible. Real-time spectrum analysis with a bandwidth of 80 MHz, with tools such as persistence mode and a frequency mask trigger, deliver important information on critical and hidden signals.
