Limit Lines

[antony.g]

Overview
Example code written in LabVIEW which implements limit line testing. Measured X and Y values are compared to a number of user defined limit lines.

 
Description
Useful for checking if a frequency response (Spectrum Analyzer trace) or waveform (DAQ or Oscilloscope trace) are within certain limits. Any number of limit lines can be defined, limit lines can be diagonal.

Includes a VI for adding points to the original data using interpolation / curve fitting.

 
Requirements

LabVIEW 2012 (or later)

Steps to Implement or Execute Code

1) download the zip and extract the play limit line.vi 

2) run the vi with relative library file
