EMScannerR+ - 6 GHz High-Resolution Near-Field EMI Scanner

150 kHz to 6 GHz | Internal spectrum analyzer | Down to 0.06 mm

EMScannerR+ near-field EMC and EMI diagnostic system

Application and capabilities

EMScannerR+ helps engineers locate and compare PCB emission sources across a 316 x 218 mm scan area. Its eight selectable resolution levels run from 7.5 mm down to 0.06 mm for detailed investigation of dense boards. The internal spectrum analyzer simplifies the measurement setup; a user PC runs EMViewer.

  • Locate emission hot spots, current paths, RF leakage and intermittent sources on operating PCBs.
  • Compare design revisions, filter changes and shielding modifications using repeatable scan settings.
  • Use spectral, spatial and combined scanning in EMViewer; retain peak-hold results and compare scans.
  • Support scripting, limit lines and reports for engineering investigations.

System components

Documented system components

  • EMScannerR+ scanning system

  • DUT power, fixtures and appropriate RF/control connections

Measurement workflow

StepWhat the engineer does
1. Configure Choose the frequency band, analyzer settings and scan area; connect the DUT and measurement system.
2. Locate Run a spectral or spatial scan to identify frequencies and emission hot spots.
3. Investigate Refine the region, probe position or resolution while keeping the setup controlled.
4. Compare Repeat after a design change, compare results and retain maps and reports.

Software and configuration

EMViewer links scan position with RF measurements. Available modes include spectral sweeps, spatial hot-spot maps and combined scans. Confirm the supported software release, analyzer driver, license and support term when configuring the system.

EMViewer software information | Spectrum-analyzer compatibility

Scan times are examples tied to scan area, frequency span, RBW and resolution; the finest resolution is not a full-area real-time scan.

Dielectric-withstand values are test ratings, not a blanket safe operating-voltage rating for an energized DUT.
