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 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

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 devices 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.

Absolute Accuracy Formulas

AbsoluteAccuracy = Reading · (GainError) + Range · (OffsetError) + NoiseUncertainty

GainError = ResidualGainError + GainTempco · (TempChangeFromLastInternalCal) + ReferenceTempco · (TempChangeFromLastExternalCal)

OffsetError = ResidualOffsetError + OffsetTempco · (TempChangeFromLastInternalCal) + INL_Error

NoiseUncertainty = (RandomNoise · 3) / √ 10,000, for a coverage factor of 3 σ and averaging 10,000 points.

*

Absolute accuracy at full scale on the analog input channels is determined using the following assumptions:

TempChangeFromLastExternalCal = 10 °C

TempChangeFromLastInternalCal = 1 °C

7/18 www.ni.com

number_of_readings = 10,000

CoverageFactor = 3 σ

For example, on the 10 V range, the absolute accuracy at full scale is as follows:

GainError = 65 ppm + 7.3 ppm · 1 + 5 ppm · 10

GainError = 122 ppm

OffsetError = 13 ppm + 23 ppm · 1 + 60 ppm

OffsetError = 96 ppm

NoiseUncertainty = (270 μV · 3) / √ 10,000

NoiseUncertainty = 8.1 μV

AbsoluteAccuracy = 10 V · (GainError) + 10 V · (OffsetError) + NoiseUncertainty

AbsoluteAccuracy = 2,190 μV

Accuracies listed are valid for up to one year from the device external calibration.
