Accelerate Automotive Design and Test
with Flexible, High-Performance Platforms
Introduction
The automotive industry is moving quickly to proactively adapt the advantages and benefits of
electronic engineering. Specifically, wireless, radio frequency (RF), digital, and millimeter wave
technologies provide increased safety of passengers and pedestrians, more in-car convenience
and entertainment features, as well as, future self-driving and "green" cars.
Two good examples of emerging technologies for increased automotive safety include 360 degree
automotive radar which detects any potential risks around a car and helps a driver avoid accidents
with advanced emergency braking, blind spot monitoring, lane change assist, adaptive cruise control,
parking assist, front and rear cross traffic alert, and more. Secondly, wireless technologies including
802.11p will link each car on the road. These Connected Cars (Car to X) will then share information
on road and traffic situations to provide any warning(s) of potential hazards, letting nearby cars take
appropriate action.
More and more cars today are applying better telematics and infotainment features for in-car
convenience and entertainment services, with higher performance video and audio capabilities,
advanced navigation, and in-car wireless hot spot service with high-speed digital automotive
communication technologies. These new and existing digital technologies include BroadR-Reach,
MOST150, CAN, LIN, and FlexRay, as well as, the wireless technologies of 3G, 4G, Wi-Fi, Bluetooth,
Near Field Communication (NFC), and more.
The ultimate goal of incorporating various advanced technologies into vehicles is to enable
autonomous automobiles to come to fruition more quickly, saving more lives and providing an
improved overall driving environment. Both traditional automotive manufacturers and suppliers,
as well as electronic-based newcomers are developing self-driving and more environment friendly
cars with advanced radar, wireless, navigation system, digital imaging, RF sensors, and advanced
electronic power storage technologies.
Applying advanced technologies offers enormous benefits; however, it also brings to the forefront new
design and test challenges for developers and manufacturers working in the advanced automotive
industry. Based on its 75 years' experience and technical knowledge of RF, millimeter wave, wireless,
and high-speed digital design and test, Keysight Technologies, Inc. provides broad and powerful
automotive design and test solutions from early R&D to manufacturing stages, helping solve new
automotive design and test challenges while you develop and manufacture advanced vehicles
designed to save lives.
Testing and Characterizing Automotive Serial Buses
Today's automobiles include a
variety of serial buses including
I2C, SPI, UART, CAN, LIN, FlexRay,
BroadR-Reach, and MOST.
Automotive serial buses must
be able to operate reliably in the
harsh electrical environment of
the automobile where random
and infrequent transients occur.

standards body specifies required
tests for physical layer compliancy. For
each standard, Keysight's Infiniium
oscilloscopes offer fully automated
applications that perform 100%
testing of physical layer compliancy.

Debugging, characterization,
validation and reliability
testing at temperature
Temperatures, both high and low,
affect the performance and reliability
of electronic components, assemblies
and systems. The temperature
extremes that automotive electronics
are subject to are some of the most
severe in the electronics industry.
Measuring the performance of
electronic components, assemblies
and systems at these extremes with
an oscilloscope requires specialized
oscilloscope probes that have been
designed to perform under these Extreme Temperature Probing solutions
conditions.
Keysight offers a series of Extreme
Temperature Probing solutions for
oscilloscope measurements for both
voltage and current at temperature
ranges up to -55 to +150
