Application and Technology
NI-STC3 Timing and Synchronization Technology
NI X Series multifunction DAQ devices include the NI-STC3, an ASIC designed by NI for advanced timing, triggering, and synchronization. This technology includes the following:
Four counter/timers with more functionality than ever before, such as the ability to create a finite pulse train with a single counter
A 100 MHz timebase for faster triggering response and more precise generation of analog and digital sample clocks
Independent analog and digital timing engines
Retriggerable measurement tasks for analog I/O, digital I/O, and counter/timers
Native PCI Express Interface
In contrast to a PCI-to-PCI Express bridge chip, which limits the bandwidth of the device to that of the PCI bus and introduces latency, PCI Express and PXI Express X Series
devices use a native x1 PCI Express interface that provides up to 250 MB/s in each direction. National Instruments has also optimized this interface for low latency in single-point
control applications. You can use X Series PCI Express boards in any PCI Express slot from x1 up to x16.
NI Signal Streaming
USB X Series devices include patented NI Signal Streaming, a technology that uses message-based instructions and device-side intelligence to ensure high-speed, bidirectional
data transfer over USB. With USB X Series, you can concurrently transfer analog, digital, and counter data in both directions. The total device throughput over USB is
PC-dependent; on some systems, up to 32 MB/s sustained transfers are possible.
Improved Mechanical Enclosure
USB X Series devices introduce a redesigned, extruded aluminum enclosure with an easy-access magnetic lid. This lid keeps signal wiring secured and shielded and can be
opened easily when needed. The underside of the lid has a device-specific pinout label so that you can quickly determine the corresponding screw terminals for a given channel.
The enclosure also includes a lockable USB port to prevent accidental removal during operation and a security slot that can be used with ordinary laptop locks to secure the
device to a desk or workstation.
Board-Only Form Factor for OEM Applications
USB X Series devices are also available in a board-only form factor that is intended for high-volume OEM applications. These devices include standard 34-pin and 50-pin IDC
connectors for easy mating to a daughter board, which can contain custom signal conditioning and connectivity.
Software Enhancements
2/18
www.ni.com
Software Enhancements
PCI Express and PXI Express X Series devices are compatible with NI-DAQmx Version 9.0 or later driver software. USB X Series devices require NI-DAQmx Version 9.2 or later.
More than a basic driver, NI-DAQmx includes the NI Measurement & Automation Explorer (MAX) configuration utility, the DAQ Assistant for rapid development of basic
applications, and hundreds of example programs for NI LabVIEW and text-based languages. NI-DAQmx also includes LabVIEW SignalExpress LE basic data-logging software.
NI-DAQmx 9.0 introduces the ability to synchronize multiple PCI Express or PXI Express X Series devices with a single NI-DAQmx task, which previously took several tasks and
manual routing of clocks and triggers. This version also introduces the fastest, easiest way to acquire measurement data to disk in the Technical Data Management Streaming
(TDMS) format with the new Configure Logging VI. NI-DAQmx 9.2 introduces the ability to log acquired data to TDMS files within the DAQ Assistant Express VI.
With NI-DAQmx and intuitive LabVIEW graphical programming, you can easily develop applications that take advantage of today's multicore systems so you can perform
acquisition, signal processing, and data logging on different CPU cores.
Simultaneous Sampling X Series
Some X Series devices for USB and PXI Express offer simultaneous sampling, with the same channel counts and connectivity as multiplexed devices.
Unlike multiplexed devices that reduce sampling rates as you add more channels, you can use simultaneous sampling devices to maintain sampling rates as you expand the
number of channels. Simultaneous sampling X Series devices are available with up to 16 differential channels per device, and, with PXI Express, you can sample more than 200
channels simultaneously.
Simultaneous X Series devices for USB include 32 or 64 MS onboard memory to ensure the transfer of finite acquisitions, even in the presence of heavy USB traffic.
Applications
Acquisition and Visualization
X Series devices include analog, digital, and counter circuitry for the most common types of static and waveform measurements. With LabVIEW, you can easily acquire the data
and view it on a variety of graphs and displays. You can use configuration-based wizards called Express VIs to take measurements and perform signal processing with minimal
programming.
Data Logging
Whether you are validating a new hardware design, monitoring conditions on a factory floor, or recording temperature changes during a scientific experiment, you need to take
measurements, visualize your data, and often log it to disk. With X Series multifunction DAQ, you can develop a user-defined measurement system by using intuitive graphical
programming software and incorporating the exact visualization, analysis, and data-logging capabilities your application requires.
Control Systems
If you need to control the temperature of a room, the speed of a motor, or the pressure of hydraulic fluids, you can use X Series DAQ hardware to connect sensors and actuators
to your computer and build the control system that meets your exact application needs. The low-latency PCI Express bus improves single-point I/O performance, and with
LabVIEW software and NI-DAQmx driver software, you can easily take sensor measurements, compare values to a setpoint, and update output signals. X Series devices also
have four counter/timers for performing quadrature encoder measurements, pulse-width modulation, pulse train generation, frequency measurements, and much more, making
them ideal for basic motor control.
Due to the inherent higher latency of USB as compared to PCI Express, National Instruments recommends that you use PCI Express or PXI Express X Series devices for
applications that require single-point control or deterministic operation.
Test Automation
X Series DAQ hardware provides analog inputs, analog outputs, hardware-timed digital I/O, and four counter/timers on a single device, making it a cost-effective option for basic
device under test characterization and test automation. With NI-DAQmx software, you can easily synchronize acquisition or generation on multiple subsystems, such as an analog
input and analog output channel. In addition, you can easily synchronize two or more X Series devices for further expansion by using a RTSI cable for PCI Express boards or over
the PXI Express backplane for PXI Express modules. It is possible to synchronize two or more USB X Series devices by exporting sample or reference clocks from the master
device to the slave device, and using external wiring.
Compatible Accessories
PCI Express and PXI Express X Series devices use either a single or dual-stack 68-pin VHDCI female connector, depending on the number of analog and digital channels on the
device. National Instruments offers several options for cables, from 0.5 m to 10 m and from low-cost to high-performance with shielding. Connector blocks are available with screw
terminal, BNC, or custom connector types.
For measurements requiring signal conditioning, you can use X Series with SCXI signal conditioning modules.
You can purchase DIN-rail or panel mount kits for USB X Series devices as well as replacement power supplies and latching USB cables. See the model page for ordering
information.
Upgrading
Because X Series DAQ devices use the same NI-DAQmx driver software as NI M Series DAQ devices, upgrading is easy. In addition, PCI Express and PXI Express X Series
devices use the same VHDCI connector as PCI and PXI M Series. You can reuse your code and preserve your investment in accessories. The pinouts for X Series devices are
backward-compatible with M Series devices.
