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.
