Emission Measurement System for PCB EPS-3007

Niear field scanner system to "visualize" the inteference properties of the circuit board

Product catalog

GENERAL

The EMC PRECISION SCAN is a scanner system to measure RF near-field emissions from a printed circuit board under test in normal offices or similar electromagnetic environments by utilizing an X-Y axis antenna probe scanning mechanism. The scanning results are represented on the user's PC monitor as frequency spectrum charts and field intensity distribution color maps, the latter of which is superimposed on the actual board image captured by the CCD camera mounted on the scanner main unit, allowing the user to easily locate the exact sources of emission.

FEATURES

Provides an amplitude versus frequency plot for each antenna probe position and field intensity distribution map by a single scan
Electric and magnetic fields are separately detected.
Wide and selectable frequency range
Fine resolution
3D graphical representation and zoom capability for a given area
Comparison before and after a modification or improvement
Scanning by a single antenna probe to minimize error between each measurement point
3GHz maximum frequency response (option)
Standard included three kinds of antenna probes (Probe A, Probe B and Probe C)
Simple and easy-to use

APPLICATIONS

This product is now used in the following applications. Our company is continuously developing various new applications in cooperation with our customers. For example:

Locates spots with higher field level compared to other spots
Locates spots with the frequency or frequency range in question, if any
Comparison of measurements resutls between before and after modifications in circuit design
Measurement for components
Evaluates the effectivness of EMI suppression components
Measurement for I/O cables
Measurement for the surface of small metal enclosure
