Teledyne LeCroy showcased 'precision measurement' and 'integrated measurement' technologies for verifying data communication required in future connected vehicles.

LeCroy participated in the '2026 Korea Electronics Manufacturing Industry Exhibition x Automotive World Korea,' held at COEX in Samseong-dong, Seoul from April 8 to 10, and unveiled measurement and verification solutions targeting automotive electronics and electronics manufacturing sites.

This exhibition is an integrated exhibition that covers the electronics manufacturing, automotive electronics, and smart factory industries together. LeCroy set up booth F164 in Hall A for the event and exhibited power semiconductor analysis solutions, the EV motor analysis solution MDA8208HD, the TDR measurement solution WavePulser 40iX, and the automotive application Automotive Ethernet 10BASE-T1S.

The most notable theme at this exhibition was 10BASE-T1S automotive Ethernet, aimed at the evolution of automotive networks.


Teledyne LeCroy describes 10BASE-T1S as IEEE 802.3cg-based 10 Mb/s automotive Ethernet, addressing the data communication verification required in today's vehicles and future connected vehicles. It is presented as a supported solution.

According to the company, the QPHY-10Base-T1S is designed to automate the testing and verification of the 10BASE-T1S and to perform PMA (Physical Media Attachment) electrical conformity testing.

10BASE-T1S is a Single Pair Ethernet technology that, according to Teledyne LeCroy's technical brief, is used to connect in-vehicle sensors, microphones, speakers, etc., to the powertrain, body, and infotainment ECUs over a range of up to 25 meters.

In addition, this technology provides enhanced bandwidth compared to existing legacy vehicle networks such as CAN, LIN, MOST, and FlexRay, and is based on a single twisted pair, offering advantages in terms of lightweight design and cost reduction.

The fact that an Ethernet-based software framework can be applied to the entire vehicle is also cited as a reason why 10BASE-T1S is attracting attention.

The reason LeCroy is leading the 10BASE-T1S is its verification automation capabilities that go beyond simple standard support.

The QPHY-10Base-T1S can automatically test key transmitter parameters such as output voltage, output droop, timing jitter, and power spectral density (PSD), and compiles the test results into a report along with screenshots.

Another feature is the 'Stop on Test' function, which allows you to pause measurements at each test stage, check the results, and then proceed with additional debugging.

This is seen as a highly practical feature amidst the trend of automotive Ethernet expanding beyond the R&D stage into the realm of mass production verification.

LeCroy also has a TDME solution for 10BASE-T1S.

This solution is the 10BASE-T1S'sIt provides rigger, decode, measurement/graph, and physical layer evaluation functions, and supports triggers for Beacon, ID, Commit/Sync, and CRC errors, as well as color-based decode overlays, protocol tables, PLCA timing verification, and eye diagram analysis.

This is significant in that it allows developers to go beyond simply observing signals and narrow down the problem area by examining the protocol and physical layers together.

The MDA8208HD, also featured in the exhibition booth, attracted the attention of visitors.


The MDA8208HD is a motor drive analyzer that performs three-phase electrical and mechanical power calculations based on an 8-channel, 12-bit resolution oscilloscope platform.

This equipment supports both static and dynamic power analysis and can perform correlation analysis by acquiring power section and embedded control system signals together.

It is designed to allow viewing the inverter, motor, and control system all at once by providing support for speed, angle, and torque sensors, harmonic calculation, 3-phase vector display, and dq0 conversion functions.

LeCroy also introduced 12-bit high-resolution measurement technology.


LeCroy's HDO (High Definition Oscilloscope) product family provides '12 bits all the time' from 200 MHz to 65 GHz and achieves 16 times more vertical resolution than 8-bit equipment through HD4096 technology.

This enables cleaner and sharper waveforms, more signal detail, and higher measurement precision.

"Vehicles are evolving into electronic systems that process more and more data in real time, and the importance of tools capable of simultaneously verifying networks, power, and control is growing," said a LeCroy official. "We will fully support 'precision measurement' and 'integrated verification,' which are key topics in automotive electronics development, through 10BASE-T1S automotive Ethernet, 12-bit oscilloscopes, and motor drive analyzers."
