The RFScanner is an Antenna Pattern Characterization, Measurement and Diagnostic Tool on you Lab-bench.

The RFScanner is a compact bench-top scanner that characterizes antennas in your own lab environment in real-time.

The RFScanner measures the amplitude and phase of near-field magnetic emissions and uses these data provides far-field patterns, bisections, EIRP and TRP and other parameters in seconds.

The RFScanner give insights into the root causes of antenna performance challenges and help troubleshoot far-field radiation patterns in real-time.

50% of products fail initial EMC testing… Until now!

A significant percentage of products fail to meet the targets required for EMC certification the first time they are tested. With the high cost of testing being high, the need for pre-testing a product can severely extend the budget, coupled with the time it takes for engineers and designers to investigate the origin of issues identified by the EMC test. Early-stage testing is considered the solution, and EMScanners are a time-efficient and cost-effective alternative to Chambers or Probe Testing.

 Case Studies

The instrument provides spatial and spectral scans that allow design teams to cut one to two design cycles out of their product development process. It also reduces their EMI testing time by up to two orders of magnitude.

The design team conducted the scans on the EMxpert system in their offices. In a matter of minutes, they obtained the results. Testing the design in a third party chamber would have have been weeks away.
