What NI DAQ Hardware Is Right for You?

NI USB-6451 mioDAQ device

If your measurement needs fall within ±10 VDC input/output and TTL digital signals, a multifunction I/O device provides the best performance-to-cost ratio. These all-in-one devices connect to a computer over USB or can be installed in a computer. 

 
Recommended Uses:

 

  • Desktop and workbench data acquisition
  • ±10 V input/output and digital signals
  • Sensors with 10 V output signals 
NI CompactDAQ modular data acquisition system with C Series measurement modules

For more diverse measurement options, upgrade to a CompactDAQ system. These systems include a selection of measurement modules that support various voltage and digital input ranges, a wide array of sensors, and options for isolated measurements and rugged environments.

 
Recommended Uses:

 

  • Compact vibration and acoustic measurements

  • Electromechanical component test systems

  • High-channel count, distributed systems

PXI system with Intel processor-based controller, PXI data acquisition modules, and an NI PXI SMU instrument

PXI

For optimal system performance, upgrade to a PXI system. These systems combine and synchronize instruments with data acquisition, sensor measurements, a high-speed bus, and the latest processor technology. 

 

Recommended Uses:

 

  • Production test systems for electronics where minimizing test time is crucial
