Note This is not a complete list of NI-DAQmx properties and does not include every
property you may need to configure your application. It is a representative sample of
important properties to configure for voltage measurements. For a complete list of
NI-DAQmx properties and more information about NI-DAQmx properties, refer to your
ADE help file.
Acquiring, Analyzing, and Presenting
After configuring the task and channels, you can start the acquisition, read
measurements, analyze the data returned, and display it according to the
needs of your application. Typical methods of analysis include digital
filtering, averaging data, performing harmonic analysis, applying a custom
scale, or adjusting measurements mathematically.
NI provides powerful analysis toolsets for each NI ADE to help you
perform advanced analysis on the data without requiring you to have a
programming background. After you acquire the data and perform any
required analysis, it is useful to display the data in a graphical form or log
it to a file. NI ADEs provide easy-to-use tools for graphical display, such as
