Product Description:
The R&S ESW is an EMI test receiver with excellent RF characteristics manufactured by R&S Germany and distributed by EUTTEST, featuring ultra-high dynamic range and measurement accuracy.The ESW EMI receiver meets the most stringent certification measurement specifications required by CISPR, EN, MIL STD-461, DO 160 and the FCC. With FFT-based time-domain scanning, the R&S®ESW captures and weights the interference spectrum almost immediately. The instrument's real-time spectrum analysis capability with spectrum waterfall plotting allows detailed analysis of the interfering signal and its history. The multi-view mode allows visualization of the results for multiple modes of operation.
Product Features:
- Frequency ranges 2 Hz to 8 GHz, 2 Hz to 26.5 GHz and 2 Hz to 44 GHz selectable
- Fully compliant with CISPR 16-1-1, ANSI C63.2, MIL STD 461 and FCC standards
- Highest dynamic range and highest accuracy for certified measurements
- Ultra-fast measurements with FFT-based time-domain scanning
- Optional high-pass and trap filters for ISM bands as preselection filters
- EMI Test Receiver and Signal Spectrum Analyzer Integrated into One Instrument
- Real-time spectrum analysis (R&S®ESW-K55 option) with up to 80 MHz analysis bandwidth and spectrum waterfall plots
