Does My DAQ Device Support Hardware-Timed Single Point Sampling Mode?

Hardware: Multifunction DAQ (MIO)

Problem:
Does my DAQ device support hardware-timed single point sampling mode?

Solution:
In hardware-timed single point sample mode, samples are acquired or generated continuously using hardware timing without a buffer. You must use the sample clock or change detection timing types.  Because samples have to continuously be updated from the computer to the hardware, fast connection speeds are necessary.  Support for this sample mode is therefore limited to PCI/PXI devices.

Analog Inputs and Outputs

The following devices support hardware-timed single point sample mode:
  • PCIe X Series (PCIe-63xx)
  • PXIe X Series (PXIe-63xx)
  • PCIe M Series (PCIe-62xx)
  • PXIe M Series (PXIe-62xx)
  • PCI M Series (PCI-62xx)
  • PXI M Series (PXI-62xx)
  • PCI E Series (PCI-60xxE)
  • PXI E Series (PXI-60xxE)
The following devices do NOT support hardware-timed single point sample mode:
  • B series (USB-6008, USB-6009)
  • Bus-powered M Series (USB-622x, USB-625x, USB -628x)
  • Externally powered M Series (USB-621x)
  • CompactDAQ (cDAQ) chassis  and sleeves (NI-9162, NI-9172) - This means that no cDAQ modules will support hardware-timed single point acquisitions.
  • Dynamic Signal Analyzer (DSA) hardware (PCI-44xx, PXI-44xx, NI-923x, NI-9229)**
**All DSA Hardware does not support any single point acquisition whether it be hardware-timed or on-demand.  See attached KnowledgeBase article.

Digital Inputs and Output and Counter

The NI X Series cards support hardware-timed single point digital inputs and outputs as well as counter tasks.
