William Wadkins, FPGA product manager at Digilent, outlined his company's
DAQ products. "We recently released several new products as part of our Eclypse
platform: the Eclypse Z7 development
board, Zmod ADC, and Zmod DAC," he
said. "The Zmod ADC and DAC can acquire and generate, respectively, signals at
up to 100 MS/s with 14 bits of resolution.
The Eclypse Z7 also comes with Petalinux
supported out of the box, and pre-built
Linux images are accompanied by the API
for bulk data transfer. This system allows
users to plug in their Zmods of choice and
get started prototyping new high-speed
measurement systems without directly
interfacing with the FPGA until desired."
The Eclypse Z7 with Zmod converters
is designed for high-speed instrumentation, control, and measurement. "The
best-in-class for performance-per-watt
Zynq-7000 SoC also makes this development board suitable for edge-computing,"
Wadkins said.
Newark offers DAQ products from a variety of manufacturers. "One of Newark's
best-selling DAQ products is the Keithley
DAQ6510," said Maureen Lipps, product
manager, Test & Tools. "This precision
data-acquisition/data-logging system
features the measurements, functions and
traceability of a 6.5-digit DMM plus 80
channels of instrument-grade switching.
A large 5-in. multitouch display guides users through set-up, data visualization, and
analysis, removing the necessity of a PC
and custom software for many applications." She added that the system is commonly applied to device characterization,
where a DUT resides in an environmental
chamber and is being stressed under varying environmental conditions. For users
who prefer a PC, IVI and LabVIEW drivers
are available.
"The B&K Precision DAS220-BAT, another key product in Newark's DAQ portfolio, measures and records parameters
commonly found in process applications
including voltage, temperature, current,
resistance, frequency, and pulse," Lipps
said. "It includes 10 universal integrated
analog channels with convenient screw
input terminals. For maximum ease of
use, measurement results are viewed
graphically and numerically on a 10-inch

color touchscreen and saved either to internal memory or external USB memory.
The user experience is further simplified and improved through icon-driven
menus which make the instrument easy
to navigate. The free DasLab Windows PC
software allows users to remotely control
and configure the recorder, transfer logging results and configuration files, and

view live data in graphical or numerical
format on the PC."
Lipps continued, "Pico Technology's
TC-08 is one of Newark's most popular
DAQ products. The TC-08 is an 8-channel thermocouple datalogger designed to
measure an effective temperature range
of -270 to +1,820°C. The TC-08 is also capable of measuring other sensors using
