AUTOMOTIVE TEST

target simulation for hardware- and
vehicle-in-the-loop test. For manufacturing, the company offers a reference target simulator for end-of-line
test and calibration and enables
test of radome and sensor mounting accuracy. Specific products for
automotive radar test extend from
spectrum analyzers (FSW85, for example), oscilloscopes (RTP0x4), and
vector network analyzers (ZNAxx)
to automotive radar echo generators
(AREG100A), compact test chambers
for compliance testing (ATS1500C),
and a radar OTA power-measurement
solution (with R&S NRPM-A90 OTA
antenna modules).
In addition to radar, Rohde &
Schwarz supports the test of
many other aspects of automotive technology, Meyer
said. In the area of connectivity (connecting the car to consumer
electronics, the cloud, infrastructure,
and other road users), the company offers
support for testing the conformance and
performance of eCall, GNSS, V2X, LTE-V,
5G, WLAN, Bluetooth, TPMS, RKE, and
UWB. For infotainment, the company enables the test of audio and video, including compliance across various broadcast
and connector standards, as well as the
test of car radio modules and displays
using all existing analog and digital TV
and radio broadcast standards.
Pickering Interfaces offers switching
modules-including microwave modules
can switch up to 67 GHz-designed to
work over a range of automotive applications, including radar and V2X, according
to Bob Stasonis, technical product specialist. "For ADAS applications, our line of
fault-insertion modules (Model 40-2XX)
for testing network channels including
Ethernet, AFDX, and BroadR-Reach have
impedance-controlled switching channels designed to pass AS6802 signals between the device under test (DUT) and
a network analyzer," he said. "Faults can
be inserted to see how the DUT reacts."
Stasonis continued, "Of course, there
will always be analog sensors for temperature, altitude, and so on. Our broad
range of simulation solutions addresses
a large part of this requirement."

Series of spectrum analyzer/VNAs can
be used to troubleshoot RF components,
optimize wireless antenna efficiency, and
monitor and demodulate RF transmissions in one instrument." In addition, he
said, "The breadth of our product line
and available features gives us plenty of
application coverage, but our high value
makes SIGLENT especially important to
R&D engineers."

AR RF/Microwave Instrumentation provides individual test equipment solutions
for EMC and component testing, according to Dean Landers, applications engineer.
"The key challenge facing vehicle manufacturers is the increasing complexity
of vehicles, including multiple wireless
technologies, antennas, and interactions
between components whether intended

SIGLENT in the automotive space continues "...to see increased integration of
high-speed serial communications buses
for infotainment and control, RF/radar for
safety/collision avoidance, and more EMI
measurements than ever before," according to Jason Chonko, applications marketing manager at SIGLENT Technologies
North America.
"As a manufacturer of general-purpose
test equipment, we have the tools to deliver concrete data and analysis for most
automotive applications," Chonko said.
"The real strength of our product line
is the flexibility. For example, our SVA

or not," he said. "This can result in performance and compliance issues down the
road, as more technologies are added in
the aftermarket."
To meet this challenge, the company
offers products including amplifiers, field
probes, antennas, and power meters as
well as complete testing systems designed
to meet the requirements of specific standards such as ISO 11451 and ISO 11452.
"This equipment and the testing performed
with it assures manufacturers, customers,
and regulatory bodies that the vehicles will
perform as designed within their intended
environments," Landers said.
