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.
