Outstanding RF characteristics, high dynamic range and measurement accuracy make the R&S®ESW ideal for fast and reliable certification measurements. The receiver meets the most stringent requirements in line with CISPR, EN, MIL‑STD-461, DO‑160 and FCC. Every R&S®ESW comes with an FFT based time domain scan for fast measurements. The wideband extension option has an FFT bandwidth of up to 970 MHz, enabling the receiver to measure CISPR bands C and D all at once. The high bandwidth is captured in real-time, even when CISPR detectors are enabled.

Certification measurements
The R&S®ESW is primarily intended for certification measurements in line with EMC standards. These place the highest demands on test equipment since it must correctly detect, measure and weight all disturbance signals, including pulsed, sinusoidal, modulated and intermittent signals. With its integrated preselection, 20 dB preamplifier and highly linear frontend, the R&S®ESW meets the requirements of commercial and military standards, including CISPR, EN, ETS, ANSI, FCC, VCCI, MIL-STD-461 and DO‑160. Weighting detectors, such as quasi-peak, CISPR-average and RMS-average, and the amplitude probability distribution (APD) measurement function comply with the CISPR16‑1‑1 basic standard, including edition 5. The same holds for the required 6 dB resolution bandwidths of 200 Hz, 9 kHz, 120 kHz and the 1 MHz pulse bandwidth. For MIL-STD-461, DO‑160 and ICNIRP standards, the R&S®ESW comes with resolution bandwidths in decade steps from 1 Hz to 10 MHz.
