NoiseKen EPS-02Ev3s Simplified Electromagnetic Field Visualisation System

Description

NoiseKen EPS-02Ev3s Simplified Electromagnetic Field Visualisation System

Three-Dimensional Indication (Time, Frequency, Amplitude) Simplifies EMC/EMI Debugging

EPS is an EMC/EMI debugging tool enabling designers to rapidly perform pre-measurement, failure point identification, and efficiency improvement confirmation in the EMC/EMI countermeasure process of product design.
How does it work? The software detects locations of probes by colour discrimination through the camera’s image sensors*, real-time analysis measures signal frequency, and shows a heat map by overlapping electromagnetic field strength and real images of measured objects.

*location detection method based on Patent Application 2007-223275 by National University Corporation Kanazawa University and Patent 5205547 by Noise Laboratory Co, Ltd.

Key Features

Visual EMI/EMC debugging – Real-time electromagnetic field mapping displayed as a heatmap over the test object.
Spectrum superimposition function – Display and compare up to three frequency spectra simultaneously (highest peak, range maximum, and pointer-designated point).
3D visualization (time, frequency, amplitude) – Detects transient or intermittent noise for advanced analysis.
Density display function – Highlights frequency of noise occurrences to quickly identify persistent emissions.
Comment and marker system – Annotate test points and record countermeasure effectiveness directly in the software.
Easy before/after comparison – Overlay previous measurements and highlight differences in colour.
Image recognition alignment – Automatic probe-tip detection and camera alignment for repeatable measurements.
Enhanced data analysis tools – Real-time, Max Hold, and Max Peak data views; simultaneous waveform display.
Supports external CAD integration – Measurement data can be exported and overlaid on CAD models.

Applications

EMC/EMI debugging and analysis – Identify hot spots, noise sources, and coupling paths on PCBs and devices.
Pre-compliance verification – Evaluate emissions before official testing to save certification time and cost.
Design optimization – Validate countermeasures such as ferrite cores, capacitors, or shielding directly on prototypes.
Automotive electronics – Localize noise sources on ECUs, harnesses, and vehicle systems.
Educational and research environments – Visualize electromagnetic behaviour for study and demonstration.
