Accurate and Repeatable High-Resolution EMC and EMI diagnostic with Hand held Near Field Probes on your on your lab-bench
3D Precision Technology used to assist high density board designers to use off the shelf hand-held probes and visualise the root causes of potential EMC and EMI problems during pre and post EMC compliance testing.
EMProbe enables the PCB and Design Engineers to diagnose EMC/EMI problems using regular off the shelf hand-held probes. An easy to use Robotic Arm controls the movement of the probe to any direction and an external Spectrum Analyzer provides the results. The EMViewer software is used to control the Robotic Arm and the external Spectrum Analyser collects and analyse the results.
Different types of Robotic Arms can be used, based on the desired size and resolution.
New Feature ReleaseEnvelope scanning is a major new feature added to the EMViewer software using the EMProbe.
Envelope scanning enables the engineer to define the DUT’s 3D “envelope” by setting the probe height for each scanning point, enabling close scanning that allows the probe to go between individual components. The height definitions are saved to the project file after the first calibration, allowing quick and seamless repeatable scans.
This feature is only available when using the EMViewer with the EMProbe Robotic Arm.
