Brief description

The R&S®FSW-K54 EMI measurement application adds EMI diagnostic functionality to the R&S®FSW signal and spectrum analyzer's range of functions. For precompliance measurements in preparation for certification, the R&S®FSW-K54 option includes EMI bandwidths for commercial and military applications, detectors such as peak, quasi-peak, CISPR-average and RMS-average, limit lines and correction factors.

Features & Benefits

  • EMI detectors in line with CISPR 16-1-1
    • Flexible allocation of standard-compliant EMI detectors such as peak, quasi-peak, CISPR‑average and RMS‑average for all traces
    • Fast, easy-to-read diagnostic measurements with high result reproducibility
    • Easy detection of critical disturbance signal amplitudes
  • Measurement bandwidths in line with CISPR and MIL-STD
    • Use of 6 dB bandwidths (CISPR from 200 Hz to 1 MHz, MIL-STD from 10 Hz to 1 MHz) for diagnostic measurements during development
  • Measurement markers for evaluating EMI
    • Simplified targeted analysis through measurement markers on the disturbance signal frequency
    • Direct comparison of limits through linking measurement markers to traces (max. 6) and associated EMI detector
    • Automatic searching for disturbance maxima for reliable detection of interferers
    • Critical frequencies entered in a peak list for fast evaluation with respect to EMI emission limits
  • Marker demodulation
    • Fast and reliable identification of AM and FM signals; known ambient interferers can be excluded from final measurement
  • EMI limit lines
    • Selection of limit lines in accordance with international standards included
    • Easy generation, editing and use of customer-specific limit lines
    • Fast pass-fail testing using activated limit lines
  • Frequency-dependent correction value tables
    • Database with correction value tables for EMI accessories such as antennas, clamps, line impedance stabilization networks (LISN), pulse limiters, preamplifiers, cables and attenuators
    • Easy generation, editing and storage of new correction value tables
    • High accuracy by including correction values for frequency-dependent accessories in the trace
    • Combination of several correction tables possible, for example for an antenna, a cable and a preamplifier, to compensate for the entire test setup
  • Logarithmic spectrum display

    The spectrum display with logarithmic frequency axis makes it easy to analyze measurement results over a wide frequency range and to display limit lines, test reports and measurement documentation in accordance with standards. Measurement results can be better compared with results from test receivers.

  • Spectrogram function

    The R&S®FSW spectrogram display allows users to analyze the behavior of disturbance signals versus time. Measured spectra are recorded and displayed as vertical lines lined up next to each other. Color coding indicates the amplitude. The spectrum and spectrogram are displayed simultaneously on the screen.
