National Instruments Introduces X Series
Multifunction DAQ for USB
Eight New USB Devices Offer Enhanced Digital Functionality and
Simultaneous Sampling Options
NEWS RELEASE Aug. 4, 2010 National Instruments today
announced NI X Series multifunction data acquisition (DAQ) devices for USB. USB X Series devices integrate
high-performance analog measurement and control channels, digital
I/O and counter/timers onto a single plug-and-play device, which
engineers and scientists can use for a wide variety of portable
test, measurement and data-logging applications. USB X Series DAQ
devices include up to 32 analog inputs, four analog outputs, 48
digital I/O lines and four counters. The eight new devices range
from 500 kS/s multiplexed AI to 2 MS/s/channel simultaneous
sampling AI.
NI
LabVIEW graphical programming makes it easy for
engineers and scientists to develop completely custom test and
measurement applications for USB X Series using intuitive graphical
icons and wires that resemble a flowchart. LabVIEW 2010 simplifies data logging and
analysis with a new technical data management streaming option
within the NI DAQ Assistant and the ability to export data from a
waveform graph to Microsoft Excel or NI DIAdem for post processing. USB X
Series devices use the same multithreaded NI-DAQmx driver software
as other National Instruments DAQ devices, making it easy to port
LabVIEW or text-based code from previous applications for use with
X Series.
USB X Series devices include two key technologies that make them as
powerful as they are easy to use: NI-STC3 technology for advanced
timing and triggering and NI Signal Streaming for high-speed,
bi-directional data streaming.
At the core of all USB, PCI Express and PXI Express X Series devices is NI-STC3
timing and synchronization technology, which coordinates the timing
and triggering of the analog, digital and counter subsystems.
NI-STC3 technology provides X Series devices with independent
timing engines for the onboard analog and digital I/O subsystems,
making it possible for analog and digital I/O to execute
independently at different rates or together with synchronization.
X Series devices include four enhanced 32-bit counters for
frequency, pulse-width modulation (PWM) and encoder operations, as
well as a new 100 MHz timebase that can generate analog and digital
sampling rates with five times better resolution than previous
devices.
USB X Series devices include NI Signal Streaming, a patented
technology that uses message-based transfers and device-side
intelligence to deliver high-speed, bidirectional data transfer
over USB, making it possible to perform analog, digital and counter
operations concurrently. With this technology, simultaneous
sampling now is available on two new devices, which can sample at
1.25 MS/s and 2 MS/s on each of their eight analog inputs. These
devices are available with 32 or 64 MS onboard memory to guarantee
finite acquisitions even with heavy USB traffic. The high sampling
rates on all channels make these devices well suited for portable
ultrasonic test and transient recording applications.
Each USB X Series device features a redesigned, extruded aluminum
enclosure. The new enclosure offers an easy-access lid to keep
signal wiring secure and shielded, and device-specific pinout
labels on the lid make it possible to quickly determine the
corresponding screw terminals for a given channel. The enclosure
also includes a lockable USB port to prevent accidental removal
during operation.
