Description

Finding, classifying and eliminating electromagnetic interference
Key Facts
  • EMI bandwidths for commercial and military standards
  • Standard EMI detectors: quasi-peak, CISPR?average, RMS-average
  • Linking of measurement markers to various EMI detectors
  • Limit lines and transducers for typical measurement tasks
  • Choice of linear or logarithmic scale on frequency axis

Brief Description The R&S®FSV-K54 EMI measurement application adds EMI diagnostic functionality to the R&S®FSV and R&S®FSVA signal and spectrum analyzer and the R&S®FSVR real-time spectrum analyzer. The R&S®FSV-K54 offers EMI bandwidths for commercial and military applications, detectors such as quasi-peak, CISPR-average and RMS-average, limit lines and correction factors. All electronic devices must be tested for electromagnetic compatibility (EMC) before market approval. The ability to assess and influence the EMC behavior of products during the design phase is one of the critical factors in developing a successful product. Preventing expensive product redevelopment and performing smooth certification help to ensure a timely market launch.
Features & Benefits
  • EMI detectors in line with CISPR 16-1-1
    • Flexible allocation of EMI detectors such as quasi-peak, CISPR-average and RMS-average as well as allocation of peak and average detectors to different 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
    • Diagnostic measurements during development deliver the correct amplitude of the disturbance signal thanks to the 6 dB bandwidths (CISPR from 200 Hz to 1 MHz, MIL-STD from 10 Hz to 1 MHz)
  • Measurement marker for evaluating EMI
    • Markers can be placed on the frequency of an disturbance signal to make targeted analysis easier
    • The ability to link markers to up to six traces and an associated EMI detector provides users with a direct reference to the limits
    • Automatic searching for disturbance maxima for reliable detection of time-varying interferers
    • Critical frequencies are entered in a peak list for fast evaluation of a frequency spectrum with respect to official EMI emission limits
  • Marker demodulation
    • Fast and reliable identification of AM and FM signals
  • EMI limit lines
    • Selection of limit lines that meet international standards
    • Easy generation, editing and use of customer-specific limit lines
    • Fast pass-fail test 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 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 allows to display limit lines in accordance with standards
