1. Gain Insight From Your Data With Analysis Panels

Use the Data Viewer in LabVIEW NXG to investigate captured data by sweeping through individual data points and zooming into a subset of the signal. In the Data Viewer, quickly make a data-driven decision by selecting from the 12 built-in Analysis Panels in LabVIEW NXG to apply analysis to previously captured data sets. Using an Analysis Panel, you can analyze your recorded signals by setting the parameters of the analysis function and viewing in real time the effect of the function input on your signal.

Figure 1: In the filter Analysis Panel, use a high-pass filter to remove white noise from a sound recording and create code that can be reused in a LabVIEW NXG VI. 


Create an Analysis Panel by selecting from a variety of analysis functions in the Data Viewer:

  • Fast Fourier transform
  • Curve fitting
  • Lowpass, highpass, bandpass, and bandstop filtering
  • Tone measurements
  • Pulse and transition measurements
  • Statistics


To perform the same analysis while you are acquiring data, you can reuse the code generated in the interactive Analysis Panel by copying the function to the clipboard and copying and pasting into a VI.

2. Analyze Data Inline to Get Insight Faster

Perform inline analysis in your DAQ application to view measurement results faster. You can integrate analysis into your program by analyzing signals while you are acquiring data to display results to the user immediately. Use one of the hundreds of built-in signal-processing and analysis functions in LabVIEW NXG to gain insight from your measurement data without having to create the algorithm yourself.

Figure 2: LabVIEW NXG provides hundreds of analysis functions to implement advanced and inline analysis. 


Download the example code to see how to use the built-in filtering, limit test, and power spectrum analysis functions. In the Simple Filter example program, you are simulating two sine waves with white noise and filtering out the noise using highpass and lowpass filter functions. Run this program to view the generated and filter signals, as well as modify the filter parameters to change the behavior of the functions.

Figure 3: As the sine waves are created, the signals are filtered and the results are displayed on the user interface. 


For analysis functions that have an Analysis Panel, including filtering, you can open an Analysis Panel directly from the function and modify the input parameters to apply to the function that is in your code. By using the Analysis Panel to select function parameters, you can reduce the amount of trial and error in selecting the correct input value for your application.
