Rohde & Schwarz ESU40 | 20 Hz – 40 GHz

Discontinued

The Rohde & Schwarz ESU40 has been discontinued.

Replaced by the ESW44

The Rohde & Schwarz ESU40 is an EMI test receiver and spectrum analyzer combined into a single unit, offering a fully compliant (to CISPR16-1-1) test receiver and a full-featured, spectrum analyzer. The Rohde Schwarz EMI test receiver has a large dynamic range, low inherent noise, and minimize measurement uncertainty all working together to guarantee excellent test results. The Rohde & Schwarz ESU40 is equipped with comprehensive functions such as RF scan, real-time IF analysis, and fast Fourier transform analysis that brings technicians an accurate overview for measurements. FFT-based test technique implementation by Rohde & Schwarz ESU40 can reduce measurement time by 10 to 100 times, and the cost per measurement is reduced with its high-rate preview measurement. The Rohde & Schwarz ESU40 also provides a full selection of parallel detectors, including the CISPR-Ave and the brand-new CISPR-RMS detector. All detectors (peak, AV, quasi-peak, CISPR-Ave, RMS, and CISPR-RMS) are integrated digitally, which enhances stability.
