The DLW32MH201YK2
common-mode choke coil
(CMCC) for Automotive Ethernet
(100BASE-T1) withstands
temperatures ranging from -55
to +150°C, which compares
favorably to the -40 to
+125°C temperature range of
conventional products, the vendor
said. This improved performance
has been achieved by employing
metal termination that absorbs
the stresses associated with
temperature change as well as by
optimizing the combination of the
vendor's original materials and
product design. Features include a
3.2-mm x 2.5-mm size, compliance
to AEC-Q200 (a specification
defined by the Automotive
Electronics Council), and a rated
voltage of 80 V.

The DAS30/50/60 data recorders
feature a sampling interval of
1 µs (1 MS/s), an input range of
±5 mV to ±500 V, and internal
solid-state memory to 64 GB.
With a CAT III isolation rating,
these instruments are suited for a
range of applications from sensor
signal logging to electrical power
analysis. A built-in power-analysis
application measures and records
voltage and current on both
single and 3-phase networks.
The results are displayed as a
harmonics graph, Fresnal diagram,
and oscilloscope waveform. An
integrated thermal printer is
optional for all three models.

Powered by an eighth-generation
Intel Core processor, the 4Sight
XV6 expandable vision controller
is designed specifically to handle
intensive vision applications
on the factory floor, including
warehouses, plants, and
manufacturing or fabrication
facilities. The latest addition
to the 4Sight Series, the XV6
provides a reliable platform with
expansion capabilities for video
acquisition. The 4Sight XV6 can
support intensive machine vision
applications. 4Sight XV6 vision
controllers offer desktop-level
processing performance, with
support for up to three displays,
including VGA, DVI-D, HDMI,
and DisplayPort. The 4Sight XV6
comes preinstalled with Microsoft
Windows 10 IoT Enterprise 2019
(64-bit).

8. Audio test sequence
A new SoundCheck test
sequence predicts listener
headphone preference based
on statistical models developed
by Sean Olive, Todd Welti, and
Omid Khonsaripour of Harman
International. The sequence
measures a headphone in
SoundCheck and saves the results
to an Excel template. Within
Excel, a predicted preference
score on a scale of 0 to 100 is
calculated based on the Harman
Target Response Curve. The
calculation involves subtracting
the target curve from an average
of the headphone left/right
response to obtain an error
curve and analyzing this curve to
calculate the score.
