Automotive Infotainment System
Automotive infotainment system is growing rapidly because of the advancement in
technology. More and more new technologies and devices are integrated into the system.
Connected automotive infotainment is becoming a must have feature for car manufacturers.
One of the major challenges in the infotainment system testing is the ever-growing number of
standards and protocols that are in place for audio and video broadcast, navigational standards
and cellular standards. This involves being able to validate the device under test’s capability with
each standard individually, forcing the test platform to be flexible enough to do so.
Most of the infotainment tests are functional tests which require multiple carriers to be generated
to validate the functionality of the infotainment RF tuner. For example to validate the channel
search functionality, the test system should be capable of generating multiple carriers. Traditional
instruments are capable of generating only one standard and only one carrier can be generated at
a time and do not have the flexibility to adapt to the newer standards.

In-Vehicle Infotainment Test Solution
Engineers in the automotive industry face new challenges with infotainment systems, which now
introduce additional I/O like audio, video, and RF signals into systems that already have other
sensor measurements. MaxEye In-Vehicle Infotainment test solution is powered by National
Instruments PXI Platform, Universal Radio Signal Generation Software and LabVIEW Add-on
toolkits. NI PXI platform combined with powerful software toolkits and APIs enable engineers to
perform complicated tests on the many different I/O types at the same time using one chassis.
The National Instruments PXI platform is ideal because of the modular hardware platform that
can be reconfigured with key software tools. For example, the same vector signal generator from
National Instruments can be used to simulate GPS signals and can then be re-programmed to
broadcast and simulate digital video broadcast, or DAB.
The real time bandwidth of the NI VSG (100MHz) combined with real time streaming capability
of the generated waveform from the PXI controller enabled Universal Signal Generation software
to generate multiple carrier signals simultaneously. This unique feature enabled testing of various
system level functionalities of the infotainment DUT using single PXI platform.

RF Tuner and Navigation Testing
With the traditional approach to automotive infotainment RF tuner testing the test engineers need
multiple instruments to generate different broadcast and navigational standards. For each standard
again multiple instruments are required to generate multiple carrier signals to test the some of the
critical functionality of the infotainment system such as channel search, Alternate frequency
selection, emergency and traffic announcements etc.,
The universal radio signal generator platform based on NI PXI hardware and software toolkits
powered by LabVIEW enables testing all the functional and performance tests using single PXI
hardware.
The universal radio signal generator uses the following LabVIEW Add-on toolkits to generate the
various broadcast and navigation standards.
 NI GNSS Simulation Toolkit
 MaxEye AM/FM/RDS/TMC Signal Generation Toolkit
 MaxEye DAB/DAB+/DMB Signal Generation Toolkit
 MaxEye DRM/DRM+ Signal Generation Toolkit
 MaxEye DVB-T Signal Generation Toolkit

Audio and Video Testing
The introduction of new digital audio and video technologies—such as surround sound,
encryption schemes, Full HD video has made multimedia test applications increasingly more
complex. National Instruments advanced test systems built on PXI provide automated
measurements and increased flexibility that help you get your products to market quickly while
ensuring the highest quality that consumers expect.
Audio Signal Generation/Analysis: Analog, Digital
Video Signal Generation/Analysis: Analog, Digital (HDMI, HDCP protocol, 3D, Streaming)
This solution generates video from .png, .bmp, .jpg, and .tiff files and can stream up to 32 frames
of 1080p content from memory for streaming video applications. Audio and Video Measurements
are supported with NI LabVIEW API for automated production test applications.
Automotive Protocols Testing
The NI-XNET driver software is a combination of accelerated Controller Area Network (CAN),
Local Interconnect Network (LIN), and FlexRay interfaces; an optimized driver; easy-to-use
APIs; and configuration and debug utilities. With NI-XNET interfaces, you can develop
applications for prototyping, simulating, and testing CAN, LIN, and FlexRay networks faster and
more easily in NI LabVIEW.
HMI Testing
The complexity of infotainment HMI software is growing with functionalities and complexity of
infotainment systems very strongly . A user interface giving a faultless experience is one of the
most important requirements of today’s infotainment systems. Traditionaly HMI tests are done
manually and it takes significant time during design validation and production.
Our infotainment HMI testing is customized and the complete testing is automated using NI
LabVIEW and TestStand software platform.
Advantages of our solution
Traditional Instruments NI PXI Platform (Software Defined Instrumentation)
Multiple Instruments – separate instrument for each test Single PXI platform for complete infotainment testing
Hardware upgrade – Requires new instrument for every
new feature
Same PXI instrument can be upgraded with new PXI modules for
specific test requirement
Complex Test software architecture required to handle
multiple instruments
Relatively simple test software architecture because all the
modules are connected to the PXI controller through PXI
backplane.
Complicated test setup because of cable connections and
switching the connections during test automation requires
external switches
Simple test setup
Can generate only one carrier at a time this limits the
number of test cases that can be executed. Requires
additional hardware for each carrier.
Single hardware capable of generating multiple carriers and this
enables tests like channel search, up/down, channel selection,
Alternate Frequency tests, HMI tests etc.,
Requires technical support and calibration services from
multiple vendors
MaxEye will be the single point of contact for all hardware and
software related issues
Difficult to replicate the test setup for multiple locations Simple test setup and easy to replicate in multiple locations

The name "MaxEye" comes from Communication Engineering. Our logo symbolizes the Eye
Diagram. The Eye Diagram is a Signal display pattern in which the digital signal in the receiver is
repetitively sampled. The signal is plotted every symbol period or multiples of the same. The
pattern is so called because it appears like a series of eyes between two parallel rails. This pattern
is usually used to diagnose the timing synchronization in a digital receiver. An open eye pattern
corresponds to minimal signal distortion or in other words can conclude a near perfect time
synchronization. A clear open eye pattern is also called "MaxEye".
