TOYO Introduces Emissions Measurement and Analysis Software “EPX/VE” for Automobile and On-vehicle Equipment

New Software Enables Anyone to Conduct Measurements and Perform Analysis Like an Experienced Engineer

Tokyo, Jan 8, 2020 – TOYO Corporation (HQ: Chuo-ku, Tokyo Japan, President and CEO: Masaru Gomi) announces the launch of new internally developed EMI(*1) measurement and analysis software for automobile and on-vehicle equipment. Called Vehicles and Components Emissions Measurement and Analysis Software, the application is used for measuring electromagnetic interference emissions from automobile and on-vehicle equipment and analyzing them to verify conformance to various standards including international and auto makers’ own standards.

The “EPX/VE” is a software product that measures and analyzes the electromagnetic noise emitted from automobile and on-vehicle equipment. Combined with Keysight’s EMI receiver(*2), “N9048B PXE,” this software helps prevent you from missing any noise and identify the part that emits noise along with the location of the noise source. By making it easier to pinpoint the noise source, development engineers are now able to take countermeasures against such noise at each step of the development cycle more efficiently, which leads to the reduction in overall development time.

The “EPX/VE” supports the conformance test and ease of evaluation against EMI standards for automobile and on-vehicle equipment in various countries and regions.


Background / Feature
The “EPX/VE” is TOYO’s original software and was developed by One Technologies Company, an in-house TOYO company engaged in product development. An operator can measure and record the electromagnetic noise emitted by automobile and on-vehicle equipment using an EMI receiver and analyze the measured data on the “EPX/VE” to check whether the product complies with various standards.

There have been some challenges with the above-mentioned analysis – for example, it was difficult for non-experienced engineers to find the noise source by looking at the measured data. The noise source often can be identified only by an experienced engineer’s intuition. However, by visualizing all signal waveforms including noise in chronological order, the “EPX/VE” can provide you with the timing and frequency component of the noise. You can easily isolate the part emitting noise by finding the one that has the operating cycle that matches the target signal waveform. This enables anyone to conduct the EMI measurement and analysis like an expert engineer and will help shorten the overall product development cycle.

Furthermore, the “EPX/VE” also supports the conformance test for various international, regional or auto manufacturers’ own standards and by using this software, you can easily find out if your product conforms to the relevant EMI standard.


Combined solution with Keysight “N9048B PXE” EMI receiver
With the world’s first feature called “Accelerated Time Domain Scan (A-TDS)”*3, Keysight Technologies’ new EMI receiver, “N9048B PXE” offers gapless measurement, which enables you to “constantly” monitor the spectrum in the measurement frequency range so that noise is no longer missed. When noise that exceeds the maximum allowable level defined by the standard is missed in EMI measurement conducted at each development phase and is found at the final stage of development, this will substantially increase the development time as engineers need to go back to an earlier stage and fix the problem. Due to this, development engineers have no choice but to take great pains in taking countermeasures against noise and spend much time on it. A combined solution consisting of the “EPX/VE” and EMI receiver “N9048B PXE” prevents you from missing noise when you conduct EMI measurement for automobile and on-vehicle equipment and helps anyone identify the noise source easily and quickly to save time.

*1 Electromagnetic Interference. The phenomenon in which electromagnetic waves emitted from electronics adversely affect other electronics. The EMI measurement makes sure that the emission from a product is lower than the level that affects the normal operation of other electronics. The EMI conformance test is to test a product against an EMI standard and verify the conformance (different standards are defined for each country, region or product category).

*2 Equipment for EMI measurement that records the electromagnetic wave emitted from DUT

*3 A-TDS is an optional feature.
