    • 描述: R&S ® ESR is an EMI testing receiver with a frequency range of 10 Hz to 26.5 GHz and complies with the CISPR 16-1-1 standard.

      The R&S®ESR is an EMI test receiver with a frequency range from 10 Hz to 26.5 GHz and complies with CISPR 16-1-1. The receiver can measure electromagnetic interference with conventional stepped frequency sweeps or at very high speeds with FFT-based time domain sweeps. At the same time, the R&S®ESR can also be used as a comprehensive and powerful signal and spectrum analyzer for laboratory applications. With real-time spectrum analysis capabilities and extensive diagnostic tools, the test receiver can be used to analyze interfering signals and their history in detail. The R&S®ESR features clearly structured menus and an intuitive touchscreen for easy operation in any mode.
