Key facts
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.
In line with all relevant standards
The R&S®ESW complies with CISPR 16-1-1, ANSI C63.2, MIL‑STD‑461 and FCC standards and offers all required bandwidths and detectors. Preconfigured limit lines and test automation make the receiver ideal for EMI testing in line with all relevant standards.
Compliant with all relevant standards
The R&S®ESW correctly detects, measures and weights all disturbance signals in line with EMI standards.
Time domain scan for fast measurements
Speed is crucial, especially for testing devices with short operating times. The R&S®ESW has an FFT based time domain scan (TDS) to measure large frequency segments at once rather than individual resolution bandwidths for each observation period in conventional stepped scan mode. FFT bandwidth can increase to 970 MHz with the wideband extension option for measuring CISPR bands C and D all at once. The high bandwidth is captured in real time even with CISPR detectors enabled.
Time domain scan for fast measurements
Receiver mode with bargraph display of detector values, measurement graphs relative to limit lines and peak list with individual pass/fail detection.
Designed for effective testing
The R&S®ESW has a touchscreen with a 12.1" display for convenient and intuitive operation. The receiver has two additional customizable knobs that can be assigned functions such as resolution bandwidth, RF attenuation and measurement time.
Intuitive user interface
Multiple simultaneous displays for a perfect overview. This image shows the interference analysis with the multiple CISPR APD application.
RF performance that meets highest demands
The R&S®ESW has the high dynamic range and sensitivity needed for the toughest EMI compliance testing. Low noise and built-in preselection with 21 filters enable accurate and reliable measurements.
Wide dynamic range and sensitivity
Configurable input stage. The R&S®ESW performs best with preselection and notch filters as well as preamplifiers and attenuation.
Resolution of even the shortest interference
The R&S®ESW captures signals in real time, without any time gaps and with a bandwidth of up to 80 MHz with the base unit or up to 970 MHz if equipped with the wideband extension option. Even the shortest pulses are resolved and displayed intuitively in the persistence spectrum and spectrogram, showing detected signals that would otherwise remain hidden. Sporadic, pulsed or drifting signals are easy to identify with the real-time option.
