NI X Series devices for PCI Express and PXI
Express are the most advanced data acquisition (DAQ) products ever made by NI,
with high-performance analog, digital and counter/timer functionality
integrated onto a single device. X Series DAQ devices include up to 32 analog inputs (AI),
four analog outputs (AO), 48 digital I/O lines and four counters on a single
device, and range from low-cost 250 kS/s multiplexed AI to 2 MS/s simultaneous
sampling AI. Engineers can easily define the functionality of an X Series
device in software, making them flexible enough for a variety of applications,
from basic data logging to control and test automation. The new X
Series devices also integrate a native PCI Express interface, which provides
the full 250 MB/s of PCI Express bandwidth. Some other DAQ devices use a
PCI-to-PCI Express bridge interface, which limits the device bandwidth to that
of the PCI bus. X Series devices also are optimized for low-latency I/O, for
high performance in control and single-point applications. X Series devices incorporate new NI-STC3 timing and
synchronization technology, which provides four flexible, 32-bit counters and a
100 MHz timebase for all analog and digital timing, which is a 5x improvement
over previous devices. This timing technology lets engineers
perform advanced triggering and synchronization that would have previously
taken advanced code or several DAQ devices to implement. Simultaneous X Series
devices integrate up to 16 analog-to-digital convertors on a single device at 2
MS/s per channel, which allows engineers to sample all AI channels at a high
rate in applications such as ultrasonic test and measurement.
An in-depth survey of 700 current and future users of 3D printing holds few surprises, but results emphasize some major trends already in progress. Two standouts are the big growth in end-use parts and metal additive manufacturing (AM) most respondents expect.
