Analog I/O

NetAcquire AIOTM

The NetAcquire AIO a next-generation remote data acquisition system that offers all the capabilities of the NetAcquire architecture. Not only can you monitor and control equipment that is hundreds of feet away, but NetAcquire AIO offers powerful real-time processing inside each box.

The real-time operating system used by NetAcquire AIO has been specifically designed for real-time data acquisition and control. The NetAcquire AIO 3000 offers over sixty high level commands for real-time processing, including:

  • triggering and alarms
  • sensor linearization
  • digital filtering and FFTs
  • PID control
  • statistical functions.

Being fully programmable, the NetAcquire AIO server gives you much more than a simple Networked Voltmeter – and can in fact emulate a wide range of virtual instruments. It is ideal for Automated Test where it can act as both function generator and analyzer – simultaneously generating and sampling both digital and analog, to test logic and perform high-speed time and frequency domain measurements. NetAcquire AIO also supports advanced real-time processing extensions by allowing local execution of user-supplied custom code.
