Data Acquisition and Signal Conditioning

Using LabVIEW, plug-in DAQ boards, and SCXI signal conditioning hardware, the Data Acquisition and Signal Conditioning course teaches you the fundamentals of PC-based data acquisition and signal conditioning. During the course you get hands-on experience with installing and configuring data acquisition hardware and learn to use data acquisition software functions to build your application. Although LabVIEW is the application software used during the class, users using only the NI-DAQ API will also benefit by learning about analog input, analog triggering, signal conditioning, signal processing, analog output, digital I/O, and counters. By the end of the course, you will know how to develop integrated, high-performance data acquisition systems that produce accurate measurements.

Audience:

  • Developers and users using LabVIEW, DAQ and/or signal conditioning to create data

  • acquisition and control applications

  • Developers using NI-DAQ API (with C or Visual Basic) to create DAQ applications

  • Users new to PC-based data acquisition and signal conditioning

  • Designers and users of measurement and control systems

After attending this course you will be able to:

  • Properly connect transducers such as thermocouples and strain gauges to your

  • measurement hardware

  • Use LabVIEW DAQ VIs to perform single point and continuous measurements

  • Use Measurement and Automation Explorer (MAX) to configure your data acquisition

  • and signal conditioning hardware

  • Eliminate measurement errors due to under sampling and signal grounding techniques

  • Start your measurements using hardware and software triggering

  • Use signal processing (windows and digital filters) to improve quality of acquired signals

  • Control relays and lights using analog output and digital I/O signals

  • Make pulse, frequency, and position measurements using counters

  • Generate single and continuous waveforms
