Description

NoiseKen EPS-02Ev3 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.

Short Specifications

Measurement Frequency Range: Depends on spectrum analyser and probe specifications.
Measurement Units: dBμV, dBm.
Recording Modes: Single, Free Run, Max Hold, Max Peak Data.
Compatible OS: Microsoft® Windows® 10 / 11 (English or Japanese versions).
Recommended PC Specs: Intel® Core™ i5 or higher (i7 recommended), 8 GB RAM, Full HD display.
Auxiliary Functions: Save/load/export, comment input, camera image inversion, ghost overlay, zoom functions.
Communication Interfaces: LAN and USB connections (to camera, analyser, and PC).

What's Included

EPS-02Ev3 software package with license key (USB protection dongle)
Web camera for visual mapping
Camera tripod and extension pole
USB extension cable (2m) and LAN cable (2m)
Setup media and Quick Start Guide

Compliance & Compatibility

Measurement Support: Meets the needs of EMC/EMI pre-compliance diagnostics and countermeasure verification.
Analyser Compatibility: Supports multiple standard-compliant spectrum analysers and EMI receivers per CISPR 22 / CISPR 32 frameworks.

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.

Product Images

Enhanced Comment Functionality<br />
<br />
A function has been added that allows you to display a marker at the position where you want to register a comment such as countermeasure location or notes, and to register comments on the time axis of map data and spectrograms. By registering comments for countermeasure locations in each coloured marker, you can trace the countermeasure record.

New Function: Measurement Files List Display<br />
<br />
A function to display a list of measurement files has been added, making it possible to display a list of saved measurement files.<br />
By displaying the accumulated measurement files as a list, you can comprehensively compare the countermeasures history.

Easy Comparison Before and After Countermeasures<br />
<br />
In addition to the conventional method of comparing measured data side by side, it is now possible to compare in the same range by loading a comparison target file into the same file. Also, the data difference display function allows to compare differences in measurement data by colour.

Previously taken images can be displayed overlaid for position alignment. Usage example 1: aligning the camera position with the previously taken image before the test. Usage example 2: realigning the camera position when it got misaligned during the test." src="https://telonic.co.uk/jg/wp-content/uploads/EPS-02Ev3_Alignment_TelonicUK-768x543.jpg"/>

Camera "Ghost" Function Learn more...

Measurement Pre-sets<br />
<br />
Added a new function, so that a new measurement can be performed under the same measurement conditions as the previous measurement. By loading the past measurement data, it is possible to conduct measurement under the same settings (conditions) of frequency range, RBW/VBW, etc.

Measurement in Different Sizes<br />
<br />
Various probes are applicable regardless of manufacturers. Not only small components, but also big equipment are available to measure by changing probes. Furthermore, even products with complex surface shape are measurable by adjusting camera’s position.

Easily Check the Noise Occurrence Frequency<br />
<br />
Added a function to display colours according to the frequency of occurrence (density display function) to the conventional spectrum display function. This makes it possible to easily check the noise occurrence frequency and the amplitude at the measurement frequency. A wide range of analysis is available, from checking the noise amplitude in regular measurements (using the density display function), to checking the details of areas of concern (noise with large amplitude, intermittent noise, etc.) by spectrogram measurement.

Simplified EMC/EMI Debugging<br />
<br />
In addition to conventional two-dimensional (frequency and level) measurement, three-dimensional (frequency, level, time) measurement is now possible for the space electromagnetic field visualization system that has been well received. This makes it possible to visually confirm changes in noise over time, and analyse noise causing factors such as discovering discontinuous noise.

Simultaneous Waveform Display Function Newly Added<br />
<br />
It is now possible to display FREE RUN waveforms simultaneously when displaying MAX HOLD or MAX PEAK DATA waveforms.
