NI X Series multifunction data acquisition (DAQ) devices provide a new level of performance with the high-throughput PCI Express bus, NI-STC3 timing and synchronization technology, and multicore-optimized driver and application software.

High-Throughput PCI Express Bus
PCI Express offers dedicated bandwidth of up to 250 MB/s in each direction to each device, and X Series devices feature a native PCI Express interface with optimizations for high throughput and low latency.

NI-STC3 Technology
NI-STC3 timing and synchronization technology delivers advanced timing functionality, including independent analog and digital timing engines, retriggerable measurement tasks, and four counter/timers with more functionality than ever before.

Data Acquisition Software
X Series devices include multithreaded NI-DAQmx driver software, which is compatible with the following versions (or later) of NI application software – LabVIEW 8.2, LabWindows™/CVI 7.x, or Measurement Studio 7.x; LabVIEW SignalExpress 1.x; or LabVIEW with the LabVIEW Real-Time Module 8.2. X Series devices are also compatible with C/C++ and Microsoft Visual Studio .NET. NI-DAQmx includes free LabVIEW SignalExpress LE data-logging software and hundreds of shipping examples to help you get started quickly with your application.

Since your device does not have direct signal connectivity, you need a connector block to act as an interface between your sensors/signals and your device. A connector block provides easy access to the inputs and outputs of your hardware.
You need a cable to transmit signals between your device and your signal connections on your connector block.
The chassis provides rugged, modular housing for the controller and modules and contains the high-performance PXI backplane, which includes the system's data, timing, and triggering buses.
The controller runs your application and interfaces with your PXI modules.
You need software to interface with your hardware and to collect, analyze, present, and store your measurements. This board is compatible with a variety of programming languages, including LabVIEW, C/C++, Visual Basic, and .NET. LabVIEW provides the easiest integration with all of your NI hardware and is recommended to maximize your hardware investment.
