Electromagnetic Field Visualization System EPS-02Ev3

Emission Measurement Equipment (EPS) Electromagnetic Field Visualization System EPS-02Ev3

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

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

The density display function expands the range of analysis
Added a function to display colors 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.

Three-Dimensional Indication (Time, Frequency, Amplitude)
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 analyze noise causing factors such as discovering discontinuous noise.
Simultaneous waveform display function newly added

Check the records of countermeasures locations
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 colored marker, you can trace the countermeasure record.
"Measurement files List Display" new function added

Accumulated measurement files displayed to check countermeasures history

Accumulated measurement files displayed to check countermeasures history
A function to display a list of measurement files has been added, making it possible to display a list of saved measurement files.
By displaying the accumulated measurement files as a list, you can comprehensively compare the countermeasures history.
Easy comparison before and after countermeasures

Equipped with a difference display function

Equipped with a difference display function
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 color.
Easy measurement under the same conditions as past data

read more
Idded 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.
Specified coordinate output function

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
Others
