EMxpert Software Setup and Modes of Operation Setup and Modes of Operation Setup EMxpert is a very-near-field scanning system. It is composed of 1,218 H-field probes that operate between 150 kHz and 8 GHz. Probes are wideband but not very sensitive across this band thus they are very good at rejecting background noise.
Page 25
EMxpert Software Setup and Modes of Operation 3. Cable testing Cables from and to the PCB can be tested for emissions. Place the DUT on the scanner and tape the cables on the scanner. 4. System testing EMxpert will help detect any leakages from a system under test for both frequency and location.

EMxpert Software Spatial Scan Spatial Scan A Spatial Scan measures the magnetic field of radiated electromagnetic emissions from the DUT at a single frequency as a function of position. Add Spatial Scan node to Project node (please refer to page 31).
Page 47
EMxpert Software Spatial Scan 4. Sweeps per Cell: A spatial scan operates by successively sampling the output from each selected cell in the scanner. If an intermittent signal is being measured then a single sample could easily miss the signal. The sweeps per cell option will force the scanner to stay longer at one location and sample multiple times with the result being the maximum value of all the sweeps.

EMxpert Software Spatial Scan If you choose Scan Continuously the screen will refresh quickly. If you wish, you could move the PCB on the scanner and see the result of the movement in real-time (the overlay does not move as you have fixed it to a set position).
EMxpert Software Spectral/Spatial Scan Spectral/Spatial Scan A Spectral/Spatial Scan measures the magnetic field strength of radiated electromagnetic emissions from an object as a function of both frequency and position on the PCB. The Spectral/Spatial Scan collects a series of Spatial Scans over the entire frequency range of interest as opposed to a Spatial Scan (which gathers data at single frequency) or a Spectral Scan (which saves only the composite maximum data set over the scan area).
Page 51
EMxpert Software Spectral/Spatial Scan 3. Interleaved Scan: This scan is meant to overcome the limitations of the probe polarizations. By measuring a DUT twice with a small physical shift between the two scans, blind spots can be eliminated (please refer to page 64).

Continue with re-placement of probe and triggering until all locations selected have been triggered. You can also make use of a simple grid to help place the probe.
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.
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.
EMxpert Software Interleaved Scan Interleaved Scan The Interleaved Scan node is meant to overcome the limitations of the probe polarizations and remove blind sports. Each of the 1218 probes on the EMxpert scanner is created by using the vias and traces in a PCB to form a loop.
Page 65
EMxpert Software Interleaved Scan In certain situations the presence of dead spots can create misleading results. An example of this is shown below. The image on the left shows a diagonal trace with one standard scan. The image on the right shows the same trace after two interleaved scans.

EMxpert Software Interleaved Scan b. Run the first spatial scan: Place the DUT on the scanner at the desired position. This position should align with the Gerber file overlay. Run the first scan. c. Run the second spatial scan: After the first scan, a message box will pop-up indicating to move the DUT up by exactly 1 row.
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.
To combat this effect a small surface wave absorber must be placed on the edge of the scanner. This absorber is provided by EMSCAN with the EMxpert EHX system. If you are missing your absorber please contact EMSCAN.
If the scan amplitudes are below 20 dBuV and the noise floor is high, use a low noise amplifier (your own or one provided by EMSCAN) and reduce the Resolution Bandwidth. g. We take measures to compensate for spectrum analyzer noise.
