multiplexer module, offers expanded
measurement types and ranges over its
predecessors, and streamlines your test

test software."

WebDAQ, for both temperature and sound
and vibration measurements. These can
be used in stand-alone and remote settings but can also be controlled through a
REST API for application control and data
retrieval by popular programs including
Python, C++, and LabVIEW. MCC has also
released professional-quality DAQ products in the Raspberry Pi HAT (Hardware
Attached on Top) form factor. The first
three releases are a 100kHz, 12-bit analog
waveform capture module, a digital IO
and analog output module, and a thermocouple measurement module."
Chitalwala, Yokogawa: "We released
the DL350 Portable ScopeCorder a year
back. It combines all the measurement
and recording capabilities engineers need
when they are away from their office or
laboratories-all in one compact instrument. Some of the key features include:
Portability, mobile, and modular; A4sized compact chassis; up to 3.5 hours of
battery power; resistive touchscreen for
harsh environments; GPS recording; and
16-bit, 100MS/s, up to 8 channels."
Chamberlin & Cole, Silicon Designs:
"The G-Logger data acquisition system
series from Silicon Designs is available in
two unique models, known as the Model
3330 and Model 3340, respectively. Both
are portable, low cost, USB-powered data
acquisition systems, designed expressly
for use with all Silicon Designs 8-32 VDC
MEMS capacitive accelerometer modules. All models in the Silicon Designs
G-Logger DAQ series provide the same
quick, powerful monitoring and real-time
data streaming, as well as analysis and
display capabilities, as can be found in
more expensive data acquisition systems,
including 16-bit sample rates from 1 to
10,000 samples per-second-per-axis."
Nguyen, DTS: "We recently released SLICE
IP68, which is a modular, ultra-small DAQ
in a waterproof, dustproof enclosure with
IP68-rated connectors. It's a proven DTS
form factor combined with unparalleled
environmental durability that's allowing customers the ability to collect in
situ vibration, strain and rotational data
without special weatherproof enclosures

Silicon Designs' Model 3330 and
Model 3340 G-Logger Data Acquisition System.

Rovini, Spectrum Instrumentation:
"Spectrum has released a full range of 16bit digitizers available for PCIe and LXI
platform. Products range from 20 MS/s
to 125 MS/s and can be synchronized up
to 128 channels in one system. The PCIe
products offer a high data throughput of
more than 700 MByte/s allowing data
acquisition and storage to disk arrays
for hours."

or slip rings. UAVs, helicopters, rockets,
military vehicles, and more."
Ang, Keysight: "Keysight recently
launched the DAQ970A Data Acquisition
System, enabling our customers to sample more signals, faster. The successor
of the popular 34970A/34972A DAQs,
the Keysight DAQ970A comes with advanced built-in 6 ½ digits digital multimeter that enables users to measure with
confidence, in terms of its accuracy. It
has built-in signal conditioning circuitry
that enables time and cost savings for
configuring complicated test setups.
The DAQ970A speeds test development

Ide, Hioki USA: "We recently launched our
Memory HiCorder MR8740T, which can
measure up to 108 channels simultaneously; offers real-time data save to SSD
unit with 5MB/s; and generates and measures signals with a single instrument."

Applications
What specific applications are vendors'
DAQs being used for?
Johnson, Digilent: "Since our devices can
run in a stand-alone mode, it is possible
to embed them in mobile devices with a
wireless connection back to PC. This has
opened up some interesting applications
in mobile robotics, drones, and machinery
monitoring where wires or cables running
back to a PC are impossible. Additionally,
by running the device off a battery, the
complete data acquisition system is isolated, allowing for inherently safe setups
around high voltages."
