out of the box. Additionally, through our
DataPlugin technology, engineers can
normalize data in over 1,200 formats,
removing barriers that closed solutions
introduce to the engineering workflow."
RADX LibertyGT modular COTS system.

RADX offers DAQ products that build
on National Instruments' technology.
"RADX has developed the LibertyGT suite
of COTS, modular, real-time, softwaredefined turnkey DAQ solutions that employ the National Instruments FlexRIO
PXIe-57xx (and PCIe-57xx) family of
FPGA-enabled, high-speed serial DAQ
products," said Ross Smith, RADX cofounder and CEO. "The NI PXIe-57xx
family includes digitizers, signal generators, and transceivers that include
Xilinx Kintex Ultra FPGAs and DDR3. NI
FlexRIO PXIe-57xx DAQ modules, combined with RADX Measurement Science
Firmware and Software (MSFS), enable
users to quickly and efficiently deploy
PXIe-57xx-based DAQ solutions, without
having to develop their own applications."
Smith said RADX COTS DAQ solutions
are available either as an integrated, turnkey system that is ready "out-of-the-box" or
as an "integration kit" that includes RADX
MSFS apps and accessories including
a 22-in. touchscreen interface that customer can add to their existing systems.
"In addition, RADX has developed USBControlled Signal Conditioning Modules
(SCM3) that provide amplification and attenuation for both RX and TX applications
for the FlexRIO products that enable users
to easily integrate the FlexRIO modules
into their applications," Smith said.

Measurement Computing Corp. (MCC)
offers a range of data-acquisition and
datalogger devices, such as the MCC 152
voltage-output and DIO HAT (Hardware
Attached on Top) add-on board for
Raspberry Pi-based systems. "We focus
on ensuring that MCC systems are easy
to use, easy to integrate, and easy to support," said Peter Anderson, general manager. "MCC has seen a huge increase of
interest in implementing DAQ and datalogging solutions around low-cost Linux
minicomputers like the Raspberry Pi.
When paired with a DAQ device, these
units provide a perfect platform for edge
computing, industrial IOT, agile development, and product prototyping."

add-on board for Raspberry Pi-based systems.

Anderson said, "MCC offers a powerful
and attractive, yet simple application-
DAQami-for data visualization and collection from any USB or Ethernet-based
MCC data-acquisition device," Anderson
said. "For customized applications MCC
offers DASYLab, an icon-based application development environment for data
collection, reduction, and analysis. Both
these environments are easy to learn
and use-reducing development time
and cost."
Pico Technology offers PC-based data
loggers for measurement of voltage,

current, temperature, and numerous
user-defined parameters, according to
Trevor Smith, business development
manager. "The loggers are compact devices that connectare to a host computer
and powered over a USB or Ethernet interface," he said. "They are supplied with
PicoLog 6 data-acquisition software that
enables easy configuration of one or more
loggers to capture, display, store and analyze data."
Smith elaborated on the software.
"PicoLog 6 is our main tool for data collection and results presentation," he said. "It
has additional tools such as Alarms, Math
Functions and Waveform Annotations.
The file system can store huge datasets,
limited only by the size of the hard disk
or SSD on your computer."
Smith continued, "At the heart of
PicoLog 6 is a robust file system that is
resistant to data loss and corruption.
If the computer is shut down and rebooted, PicoLog resumes capturing
without losing the previously stored
data. Data is stored automatically
without the need to provide a file
name and location-but if you wish
to save data to a file, you can, even in
mid-capture. This makes it easy to
share data with fellow PicoLog users."
VTI Instruments, a product line
in AMETEK's Programmable Power
business unit, offers data-acquisition instrumentation on each of
two platforms, PXI Express and
LXI, according to Chris Gibson, senior product manager. "The PXIe systems
are designed for interoperability with the
LXI interface to enable tight integration
into hybrid test systems that offer the
advantages of both platforms," he said.
The PXIe line includes the EMX-425x and
EMX-43xx digitizers with up to four 24bit, 625 kS/s channels, the EMX-2500
Gigabit Ethernet remote controller with
an LXI interface and IEEE-1588 synchronization lines, and the CMX09 and the
CMX18 enclosures with up to 18 PXIe
slots and 8-GB/s backplane bandwidth.
The LXI product line includes EX1200
Series mainframes as well as switch, sensor-simulator, resistor-ladder, and comparator/event-detector modules. Gibson
added that the EX1200 multifunction
