Application and Technology

NI-STC3 Timing and Synchronization Technology

NI X Series multifunction data acquisition (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.

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.
