– Key Features
Flexible I/O architecture supports mixed-signal applications without external multiplexing. Dual data transfer pathways—DMA and interrupt-driven—enable sustained high-speed acquisition or low-latency event handling. Self-calibration eliminates drift compensation overhead. RTSI synchronization allows phase-coherent measurements across multiple boards.
– Typical Applications
Data acquisition in transducer-rich environments, electrical characterization of components, real-time process monitoring, and distributed measurement systems requiring clock synchronization.
– Compatibility & Integration
Works with NI SCC and SCXI signal conditioning modules. NI-DAQmx driver simplifies configuration and measurement setup. Compatible with PXI-based systems via trigger bus.
