Very-Near-Field EMI/EMC Scanning Device
EMScanner is a self-contained very-near-field scanning device which connects to a spectrum analyzer or a desktop PC running a copy of EMScanner Software. The EMScanner system operates from 150 kHz to 8 GHz and delivers repeatable and reliable results that pinpoint the cause of design failure in seconds.
With EMScanner design teams can personally test their designs 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, and the results provide concrete verification of the effectiveness (or not) of the design change.
EMScanner 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.
Ideal PCB projects for EMScanner are 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 compact, flat scanner provides PCB design teams with an easy-to-use, cost effective, and proven tabletop solution. Emission, immunity, filtering, EMI shielding, broadband noise and Common Mode testing are some of the applications that the EMScanner system addresses in mere seconds.
Capability
Spectral scan, spatial scan, peak-hold, continuous scanning, spectral and spatial comparison, scripting, limit lines and report generation.
Spatial Scan Time
Continuous real-time or sub-second single scan for entire scan area Dependent on spectrum analyzer performance.
Spectral Scan Time
45 seconds for L 10 cm x W 10 cm (L 4” x W 4”) PCB with a 100 MHz span and 100 kHz RBW. Scanning area, span and RBW are user selectable within spectrum analyzer specifications.
