- At the 2022 German EMV trade fair in Cologne, Rohde & Schwarz presented an upgrade of its R&S ESW series EMI test receiver with a real-time measurement bandwidth of up to 970 MHz.
In order to speed up measurement time and to provide a more careful analysis of interfering signals, the R&S ESW EMI test receiver will offer the possibility to increase its FFT (Fast Fourier Transform) bandwidth to 350 MHz with the new R&S ESW-B350 option, and to 970 MHz with the new R&S ESW-B1000 option. According to Rohde & Schwarz, this is a market record.
With the R&S ESW-B1000 offering 970 MHz of FFT bandwidth, the R&S ESW can process the CISPR Bands C and D in one shot – even with quasi peak and CISPR average detectors working in parallel – offering a significant gain in measurement speed.
The 970 MHz wide spectrum is measured in real time; users benefit from a truly gapless spectrogram. Infrequent emissions can be observed over a significantly longer time and are detected with a much higher probability. Emissions from equipment under test going through a duty cycle are recorded over a broad spectrum of 970 MHz without missing the shortest pulse.
The R&S ESW-B1000 and R&S ESW-B350 will be available by the fourth quarter of 2022. Both options are hardware extensions to the R&S ESW EMI test receiver and can be retrofitted to every R&S ESW (S/N ≥ 103000).
Rohde & Schwarz is presenting the new solution at EMV 2022 from July 12 to 14 at the Cologne exhibition center.
