DAQ Devices with Hardware-Timed Single Point Sampling Mode Support

In HWTSP, samples are acquired or generated continuously using hardware timing without a buffer. Because samples have to be continuously acquired/updated and processed on a point-by-point basis, you need to use a fast, deterministic bus.

• Only PCI/PXI/PCIe/PXIe DAQ devices have the ability to support Hardware-Timed Single Point Sample Mode (HWTSP). 
• HWTSP is also supported on the cRIO platform with the cRIO-904x controllers and supported C Series modules.

NI devices that support HWTSP are listed below by task type:

The following devices in the PCI/PXI/PCIe/PXIe form factor support AI/AO hardware-timed single point sample mode:

• NI 63xx devices (X Series)
• NI 62xx devices (M Series)
• NI 60xxE devices (E Series)
• S Series
• NI 43xx (SC Express)
• NI 67xx (Analog Output, excluding NI 6703 and 6704)
• C Series Modules that are supported by NI-DAQmx and are used with an NI-DAQmx enabled CompactRIO.  Review this article to determine if your C Series module is supported by NI-DAQmx.

• NI 63xx devices (formerly referred to as X Series) in the PCI/PXI/PCIe/PXIe form factor support HWTSP digital and counter tasks per the X Series User Manual.
• C Series Modules that are supported by NI-DAQmx and are used with an NI-DAQmx enabled CompactRIO. Review this article to determine if your C Series module is supported by NI-DAQmx.

The following devices do not support hardware-timed single point sample mode for any task type:

• USB multifunction DAQ devices (63xx, 62xx)
• PXIe-6386 and PXIe-6396 on AI tasks
• USB low-cost DAQ devices (600x)
• CompactDAQ (cDAQ) chassis (9162, 913x, 917x, 918x, 9191) with all C Series modules
• Dynamic Signal Acquisition (DSA) devices (44xx). NI DSA Hardware does not support single point acquisition whether it be hardware-timed or on-demand as explained here.

• NI-DAQmx Hardware-Timed Single Point Lateness Checking
• Hardware-Timed Single Point Sample Mode
