is that smaller equipment can be purchased to support both the peak current
and the lower current used for the majority of testing. Alternatively, a system that
has a current range of the peak current
would need to be purchased, meaning a
unit with six times the capacity might be
purchased to support just milliseconds of
an application."

High-speed communication
Anritsu addresses communications in
automotive applications, having recently
released the LTE-V2X Tx Measurement
MX887068A software for its Universal
Wireless Test Set MT8870A, according
to Craig Hendricks, senior business development manager. With the software,
the MT8870A can measure Tx power,
frequency deviation, occupied frequency
bandwidth, spectrum emission mask, and
adjacent-channel leakage power, and it
can conduct modulation analysis specified by 3GPP. In addition, the bundled
LTE-V2X Waveforms MV887068A package includes general RF test-signal waveform files for nonsignaling Rx testing,
Hendricks said.
Anritsu also recently introduced its
SmartStudio NR (SSNR) environment
for interactive GUI-based functional 5G
device testing with the Anritsu Radio
Communication Test Station MT8000A
5G network simulator, which Hendricks
described as important for emerging automotive designs. "SmartStudio NR emulates the network conditions and communication between a 5G/LTE network and
mobile terminal to implement efficient
functional, application, and software regression tests," Hendricks said.
In addition, Hendricks described
the LTE C-V2X PC5 Communications
Software MX725000A as a cost-efficient
tool to evaluate products and systems utilizing the PC5 interface of cellular V2X
(C-V2X) technology. "The software links a
communications reference module, V2X
emulator software, and GNSS simulator
to support evaluation of vehicle-to-everything (V2X) PC5 communications used
in emerging vehicle-to-vehicle (V2V) and
vehicle-to-infrastructure (V2I) designs,"
he said. "It is a cost- and time-efficient
alternative to conventional solutions that

integrate expensive hardware and require
high-level protocol programming skills
to create required test scenarios emulating multiple combinations of communications and vehicle driving conditions."
Anritsu has also seen more interest in
measuring material properties of bumpers and insignias that act as radomes
in front of automotive radar antennas, according to Stan Oda, ShockLine
product manager. "Using E-band vector
network analyzers (VNAs), such as the
Anritsu ShockLine MS46522B E-band
VNA, automotive engineers are characterizing bumper materials and paints, as
well as model brand insignias," he said.
"With these measurements, engineers
can make sure these elements do not affect the radar functionality by attenuating radar signals from antennas placed
behind those components." Oda added
that Anritsu's VNA product portfolio
also includes the VectorStar broadband
220-GHz VNA. "VectorStar is a key tool

For radar and ADAS test, Keysight's
E8740A solution can perform radar signal analysis and generation across the 24
GHz up to 110 GHz range without external mixing, providing scalable bandwidth
from 1 GHz to 5 GHz, Varghese said, adding that an automation software platform covers test cases across standards
and hardware configurations, while the
W1908 SystemVue radar library provides
simulation of multitarget detection and
radar 3D scan.
For connected and V2X applications,
Varghese said the SA8700A C-V2X test
solution simplifies RF, protocol, and application-layer testing with an intuitive
user interface. "It characterizes transmitter performance and performs detailed receiver testing based on complete 3GPP and
automotive industry standards," he said.

of ICs used in automotive safety and entertainment systems," he said.
Keysight offers a full complement of
solutions for the different applications in
vehicles, according to Alan A. Varghese
at Keysight's Automotive and Energy
Solutions division. For example, "The
TS-5030 system tests infotainment and
telematics modules ranging from AM/FM/
RDS to DAB/DVB/DMB to navigation to
Bluetooth and Wi-Fi," he said. "The system
includes vector and audio signal generators, a handset test system for cellular, a
connectivity test set for Bluetooth and WiFi, and measurement for RF switching."

radar, connectivity, infotainment, EMC,
in-vehicle network, and ECU testing, according to Juergen Meyer, vice president,
automotive market segment. For automotive radar test solutions, for example,
Rohde & Schwarz supports research and
development by enabling the analysis of
radar high-frequency signals with up to
8.3 GHz of bandwidth, the generation of
interference signals to increase radar robustness, and the analysis of radome and
coating influence on signal quality. In the
area of test, validation, and compliance,
the company enables proof of compliance
