Issue Details

I'm using the Amplitude and Levels VI in LabVIEW and I want to know how the Histogram method works. What value is the VI returning from my waveform, and how does the VI find it?

Solution

The Histogram method returns the value of the bin with the highest number of hits, or the value at which the waveform crosses most often in the high and low ranges.

Additional Information

The Amplitude and Levels VI ignores bins in the middle 20% of the range of your waveform, and only reports bin values within the top or bottom 40% of the total range.

The number and size of histogram bins depends on the peak-to-peak range of your waveform and the Histogram Size input of the VI. Histogram Size specifies the number of levels, or bins, and the size of each bin is the full peak-to-peak range of your waveform divided by the number of bins.
