The NI PCI-6143 is a high-performance simultaneous-sampling multifunction DAQ board for PCI systems. Engineered around dedicated ADCs per channel, it delivers superior dynamic measurement accuracy for demanding applications including ultrasonic testing, high-energy physics, multi-axis control, ballistics, and transient signal analysis. The device operates via NI-DAQmx driver software, supporting LabVIEW, C/C++, Python, MATLAB, and additional programming environments.

– Key Features
Simultaneous sampling architecture eliminates skew across all 8 analog input channels. Dedicated ADC per channel ensures no multiplexing bottlenecks. 250 kS/s per-channel throughput sustains high-bandwidth transient capture. Physical footprint of 6.10 × 4.17 inches accommodates standard PCI slot installations.
– Typical Applications
Ultrasonic nondestructive testing, high-energy physics instrumentation, synchronized multi-axis motion control, ballistic impact analysis, and fast-transient phenomenon characterization.
