Rohde & Schwarz ESW-series EMI Test Receivers 2 Hz – 44 GHz
Description
Rohde & Schwarz ESW-series EMI Test Receivers 2 Hz – 44 GHz offer outstanding RF characteristics, including high dynamic range and measurement accuracy. It meets the most stringent requirements for certification measurements in line with CISPR, EN, MIL‑STD-461, DO‑160 and FCC. With its FFT-based time domain scan, the R&S®ESW captures and weights disturbance spectra in virtually no time. The instrument’s real-time spectrum analysis capability with spectrogram function permits a detailed analysis of disturbance signals and their history. MultiView mode delivers a straightforward display of results, even for multiple operating modes.
