R&S®ESR EMI Test Receiver

More speed - More insight - More intelligence

Key Facts

  • EMI test receiver and signal/spectrum analyzer combined in a single instrument
  • Compliant with CISPR 16-1-1 Ed. 3.1
  • Preselection with integrated 20 dB preamplifier

Brief Description

TheR&S®ESR is an EMI test receiver for the frequency range from 10 Hz to 26.5 GHz and complies with the CISPR 16-1-1 standard. It measures electromagnetic disturbances with the conventional stepped frequency scan or – at an extremely high speed – with an FFT-based time domain scan.

Features

  • Standard-compliant disturbance measurements
  • FFT-based time domain scan for ultra-fast measurements (option)
  • Realtime spectrum analysis for detailed investigation of disturbances (option)

Brief Description

The R&S®ESR is an EMI test receiver for the frequency range from 10 Hz to 26.5 GHz and complies with the CISPR 16-1-1 standard. It measures electromagnetic disturbances with the conventional stepped frequency scan or – at an extremely high speed – with an FFT-based time domain scan. At the same time, the R&S®ESR functions as a full-featured, powerful signal and spectrum analyzer for lab applications. Featuring realtime spectrum analysis capability with a wide range of diagnostic tools, the test receiver also enables detailed analysis of disturbance signals and their history. The R&S®ESR comes with clearly structured menus and an intuitive touchscreen, making it very easy to operate in any mode.
