RENT ROHDE & SCHWARZ ESW44
The Rohde & Schwarz ESW44 is an advanced EMI Test Receiver, specifically engineered to meet the rigorous demands of modern certification testing. With its exceptional radio frequency characteristics, the ESW44 excels in high dynamic range and measurement precision, fulfilling the stringent requirements for compliance with CISPR, EN, MIL-STD-461, DO-160, and FCC standards.
Equipped with a groundbreaking FFT-based time domain scan, the R&S ESW44 dramatically reduces measurement time, capturing and weighting disturbance spectra in a matter of seconds. The incorporation of realtime spectrum analysis, paired with a sophisticated spectrogram function, allows for in-depth analysis of disturbance signals, effectively visualizing their historical data. The instrument’s MultiView mode presents results in a clear, user-friendly format, accommodating multiple operating modes within a single display, further enhancing operational efficiency.
Designed for high-demand environments, particularly in the automotive and aerospace sectors, the Rohde & Schwarz ESW44 offers the widest dynamic range available, marked by a high 1 dB compression point and exceptional sensitivity due to minimal inherent noise. Comprehensive preselection capabilities include highpass filters at 150 kHz and 2 MHz, as well as specialized notch filters for license-free ISM bands (2.4 GHz and 5.8 GHz). This ensures that strong carrier signals don't compromise the instrument's dynamic range while still enabling the detection of smaller disturbance signals just outside these bands.
The ESW44 incorporates standard FFT-based time domain scanning, allowing for the completion of complex measurements, including those utilizing two CISPR detectors (quasipeak, CISPR-average, RMS-average), in significantly less time—essentially halving the overall measurement duration. Merging the functionality of an EMI test receiver with that of a highly capable spectrum analyzer, the R&S ESW delivers both precision and versatility.
