YIC EMScanner Overview

EMScanner: 150 kHz–8 GHz

High speed 8GHz Real-time EMC and EMI diagnostic tool on your lab-bench

EMScanner is a self-contained very-near-field scanning device that connects to a spectrum analyzer or desktop PC running on a copy of EMScanner Software.

The EMScanner system operates from 159 kHz to 8GHz and delivers repeatable & reliable results that pinpoint the cause of a design failure in seconds.

Product Features

  • 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 the 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

EMC and signal integrity are major concerns in the design of ultra-high speed (>2 GHz) PCBs. EMScanner enables the design engineers to diagnose EMC/EMI problems between 150 kHz and 8 GHz.

The EMScanner provides unique pre- and postEMC compliance testing that images real-time emissions. EMScanner allows engineers to visualize the root causes of potential EMC and EMI problems.

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

EMScanner delivers repeatable and reliable results that pinpoint in less than a second 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.

EMScanner consists of a patented scanner and compact adaptor, and of a customersupplied spectrum analyser and PC running EMScanner software. 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. This allows the design team to immediately analyse and compare design iterations. 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.
