Model Number Analog, Digital Analog, Digital Analog, Digital Analog, Digital Analog, Digital Back to Top 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...

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....
