  • Page 66: Spectral Overlay

    EMxpert Software Spectral Overlay Spectral Overlay A Spectral Overlay is a qualitative comparison of two frequency spectra. It displays two data sets superimposed on each other, which allows you to visually inspect data for differences, i.e. presenting a qualitative view. The Spectral Overlay node allows you to observe and compare two Spectral Scans with same resolution bandwidth and overlapping frequency range eventhough they may have different frequency ranges e.g.: Spectral 1: 10 MHz - 80 MHz and Spectral 2: 30 MHz - 120 MHz.

  • Page 67: Spectral Comparison

    EMxpert Software Spectral Comparison Spectral Comparison A Spectral Comparison is a quantitative comparison between two frequency spectra. It is generated by subtracting the values of one spectrum (Test View) from the values of the second spectrum (Reference View) at each frequency. The Compare Spectral node allows you to observe and compare two Spectral Scans with same resolution bandwidth and overlapping frequency range eventhough they may have different frequency ranges e.g.: Spectral 1: 10 MHz - 80 MHz and Spectral 2: 30 MHz - 120 MHz.

  • Page 68: Spatial Blind Spot Reduction

    The Interleaved Scan is meant to overcome the limitations of the probe polarizations. Each of the 1218 probes on the EMxpert EHX scanner is created by using the vias and traces in a PCB to form a loop. This small loop does not respond well to magnetic fields parallel to it, essentially creating a blind spot.
  • Page 69 EMxpert Software Spatial Blind Spot Reduction For All EMxpert Models This setup is to provide a cumulative sensitivity as shown in the figure below. This is a small 5x5 array taken from the larger 29x42 scanner. The effect of this different sensitivity on scan results sometimes shows up when a device is rotated.

  • Page 72: Spatial Comparison

    EMxpert Software Spatial Comparison Spatial Comparison Spatial Comparison is a quantitative comparison between two Spatial Scans that is generated by subtracting the values of the first scan (Test View) from the values of the second scan (Reference View) cell by cell. The Spatial Comparison node allows you to see the difference between two Spatial Scans at the same frequency.
