The Rohde & Schwarz ESW44 EMI Receiver is a testing instrument with outstanding RF characteristics, including high dynamic range and measurement accuracy. The ESW44 has a frequency range of 1 Hz to 44 GHz and features a 1 Hz to 10 MHz (optional 80 MHz) measurement bandwidth.

The R&S ESW44 EMI Receiver has integrated preselection filters (21 filters) as a standard and is also equipped with a highpass filter at 2 MHz, allowing technicians to suppress data carriers and disturbance signals on AC supply lines. With exceptional RF performance exceeding user demands, the ESW44 EMI Receiver features low DANL while providing a high 1 dB compression point (+15 dBm) for the RF frontend.

The Rohde & Schwarz ESW44 model 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 ESW44 captures and weights disturbance spectra in virtually no time. The instrument’s real-time spectrum analysis capability with a spectrogram function enables a detailed analysis of disturbance signals while offering a straightforward result display. The Rohde & Schwarz ESW44 EMI Receiver's MultiView mode delivers a straightforward display of results, even for multiple operating modes.
