High Resolution, High Accuracy Analog Measurements NI Multifunction I/O Devices have analog signal paths that have been meticulously designed, tested, and calibrated to ensure the highest possible accuracy is achieved across all input channels. Because of this thorough design-and-test philosophy, NI is able to provide thoroughly documented accuracy specifications to allow a complete understanding of device performance under a range of possible operating conditions. The specifications documentation for each device provides a section dedicated to understanding the calculation of AI absolute accuracy,...

Independent Timing Engines for Analog and Digital I/O Advanced timing and triggering functionality on data acquisition devices has often relied on onboard counters and complex signal routing to achieve specialized hardware-timed performance. NI’s multifunction I/O technology offers completely independent sample clocks and triggers for each different group of I/O on a multifunction device. Retriggerable acquisitions, for example, involve waiting for a trigger condition to be met, taking a finite number of samples, and then immediately rearming the trigger for the next acquisition. Using driver...

NI-DAQmx Application Programming Interface (API) The NI-DAQmx driver includes a best-in-class API that works directly with a variety of development options including LabVIEW, DAQExpress, C, C#, Python, and others. The native integration provides exceptional performance and a seamless experience without the need for manual wrapping of functions. To ensure long-term interoperability of DAQ devices, the NI-DAQmx driver API is the same API used for all NI DAQ products - meaning re-development efforts can be minimized regardless of hardware changes or upgrades. Additionally, the driver provides access...

group of I/O on a multifunction device. Retriggerable acquisitions, for example, involve waiting for a trigger condition to be met, taking a finite number of samples, and then immediately rearming the trigger for the next acquisition. Using driver software function calls to rearm the trigger risks missing the next trigger due to software latency; therefore, the best possible performance requires a hardware-timed approach. In the past, counters were the only way to implement hardware-timed retriggering, and so counters would be used to generate a retriggerable pulse train, which was then internally...

Synchronization and Integration PXI Multifunction I/O Modules use the inherent timing and synchronization capabilities of the PXI platform to synchronize measurements between multiple modules, which is ideal for high-channel-count applications. PXI builds on its CompactPCI architecture base by adding integrated timing and synchronization that is used to route synchronization clocks and triggers internally. A PXI chassis incorporates a dedicated 10 MHz system reference clock, PXI trigger bus, star trigger bus, and slot-toslot local bus, while a PXI Express chassis adds a 100 MHz differential system...
