product description

 

The Rohde & Schwarz ESW44 is an EMI test receiver with outstanding RF characteristics, including high dynamic range und measurement accuracy. It 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 spectrogram function permits a detailed analysis of disturbance signals and their history. MultiView mode delivers a straightforward display of results, even for multiple operating modes.

Features:

 

  • Standard-compliant EMI measurements
    • Certification measurements
    • Standard-compliant EMI measurements in spectrum analyzer mode
  • RF performance that meets exacting demands
    • Exceptionally wide dynamic range
    • Low DANL (typ. –168 dBm for f ≤ 1 GHz)
    • High 1 dB compression point (+15 dBm) for RF front-end
    • High third-order intercept (TOI) (typ. +25 dBm)
    • Superior measurement accuracy (±0.37 dB for f ≤ 8 GHz)
  • Integrated preselection filters and preamplifier
    • Integrated preselection filters (21 filters) as standard
    • Additional high-pass filter at 2 MHz for suppressing data carriers and disturbance signals on AC supply lines
    • Notch filters for suppressing strong carrier signals in the license-free 2.4 GHz and 5.8 GHz ISM bands
  • FFT-based time domain scan for ultra-fast measurements
    • Real-time measurement of conducted disturbance levels with simultaneous quasi-peak and CISPR-average weighting
  • Realtime spectrum analysis for detailed investigation of disturbances (option)
    • Real-time measurement with up to 80 MHz bandwidth
    • Spectrogram for seamless spectrum display
    • Persistence mode (spectral histogram) for clear identification of pulsed and continuous disturbances
    • Frequency mask trigger for precise and reliable detection of sporadic spectral events
  • Convenient operation, straightforward result display
    • Straightforward scan table
    • MultiView: straightforward display of multiple results
    • Optimized, touchscreen-based user interface for quick access to all functions
    • Integrated online help
    • Saving results and instrument setups
  • Automated testing
    • Preview measurement – data reduction – final measurement
    • R&S®EMC32 EMC measurement software for remotely controlled measurements and automated EMI test routines
