YIC EMProbe DBM Overview

EMProbe: 1,218 H-field probes

Accurate and Repeatable High-Resolution EMC and EMI diagnostic with Handheld Near Field Probes on your lab-bench

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.

Product Features

Using Handheld probes to identify and resolve EMC/EMI issue testing has never been this accurate. 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.

EMC and signal integrity are major concerns in the design of high-speed PCBs. While EMScanner allows designers to easily locate emission by placing the PCB on its flat surface, the EMProbe allows users to test the component side of the PCB and adjust the height of the scan.

This enables the design engineers to diagnose EMC/EMI problems limited only by the choice of the Spectrum Analyzer and the Near Field Probe and allows them to visualize the root causes of potential EMC and EMI problems of a non-flat surface or of a complete product.

During any new product development process, design engineers must find, characterize, and address unintended radiators or RF leakage to pass compliance testing. EMProbe allows board designers to pre-test and resolve EMC and EMI problems early on, thus avoiding unexpected EMC compliance test results.

EMProbe delivers repeatable and reliable results that pinpoint the cause of a design failure.

As a result, the user can personally test the design without having to rely on another department, test engineer, or time-consuming off-site testing. After diagnosing even an intermittent problem, the engineer can implement a design change and retest. The results provide concrete verification of the effectiveness (or not) of the design change.

The EMProbe solution consists of a computer controlled Robotic Arm, Near Field probe and a customer-supplied Spectrum Analyzer, all controlled by the included EMViewer SW.

The EMProbe diagnostic capabilities allow design teams to reduce testing time by more than two orders of magnitude. Users have also documented fifty percent reductions in design cycle times. This allows the design team to immediately analyse and compare design iterations.

Ideal projects for the EMProbe are components side testing of boards designed for high speed, high power, and/or high density/complexity. Any PCB that places a premium on board real-estate also qualifies as an excellent candidate.

The EMProbe provides an easy-to-use, cost-effective, and scalable solution for design teams. Emission, immunity, filtering, EMI shielding, broadband noise and Common Mode testing are some of the applications that the EMProbe system addresses in mere seconds.
