EMProbe

EMC probes with 3D precision technology

EMProbe: 1,218 H-field probes

EMC/EMI issue testing is straightforward and accurate with 3D precision technology.

Used to assist high-density board designers to use off-the-shelf hand-held probes and visualize the root causes of potential EMC and EMI problems during pre and post-EMC compliance testing.

3D Precision Technology is used to assist high-density board designers to use off-the-shelf hand-held probes and visualize 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 in 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 analyses the results.

Different types of Robotic Arms can be used, based on the desired size and resolution.

New Feature Release

Envelope 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.

Testimonials

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 been weeks away.
