YIC Technologies EMScannerR High Speed 8GHz High Resolution EMC & EMI Diagnostic Tool on your Lab Bench
The EMS08R - EMScannerR from Y.I.C. Technologies consists of a patented scanner fitted a compact controller, and a PC running EMViewer software.
The EMScannerR Model has improved resolution down to 0.06mm and suitable for high density PCBs and chips. An ideal tool for EMI Pre-compliance checking to visually identify EMI/EMC issues and solve these quickly using the software tools to locate the faults. The EMScannerR can be used with most leading brands of Spectrum Analysers, like Rigol Technologies, Keysight, Rohde & Schwarz and Tektronix (please call to check).
The patented scanner consists of an array of 1,218 H-field (magnetic) probes spaced every 7.5 mm which provides an effective 3.75 mm resolution. The EMScannerR model goes into far more detail by precisely offsetting both the X-Y axis in 0.12mm steps to further increase the resolution The system operates from 150 kHz to 4 GHz and from 150 kHz to 8 GHz with upgradable and optional software license key. The EMViewer application must also be installed on the customer-supplied PC.
EMScannerR enables the PCB and design engineers to diagnose EMC/EMI problems between 150 kHz and 8 GHz. EMScannerR provides 8 levels of resolution (60 microns – 7.5 mm). Level 1 resolution (7.5 mm) allows the engineers to visualise the hot spots, current loops or intermittent problems in real-time. After locating the unintended radiators, engineers can zoom into the problem by selecting the resolution level based on the density of the board design.
EMScannerR provides unique pre- and post-EMC compliance testing that images emissions. During any new PCB development process, design engineers must find, characterise, and address unintended radiators or RF leakage to pass compliance testing. EMScannerR allows board designers to pre-test and resolve EMC and EMI problems early on, thus avoiding unexpected EMC compliance test results. EMScannerR quickly 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.
