The NI PCIe-6361 X Series Data Acquisition Card is a multifunction I/O device built for measurement and control applications requiring high-throughput data transfer over PCI Express. It combines 16 single-ended (or 8 differential) 16-bit analog inputs, 2 analog outputs, 24 bidirectional digital I/O channels, and 4 32-bit counters/timers in a single card. The onboard NI-STC3 timing engine delivers independent analog and digital timing with 10 ns resolution and 50 ppm accuracy, supporting retriggerable measurement tasks across mixed-signal workflows.
