mesurament of peaks in a waveform

[angelito]

Hello!

I am trying to measure the peaks of a waveform. This waveform has two different levels of peaks, but I want to measure both. If I use the icon "STATISTICS" I only can measure the maximun peak of one of the peak, but not the other.

What I have done is using a "TRIGER AND GATE", I have separete the signal in two parts, but the problem is that now one of the peak only is refreshed after four period of the real signal, so I lose information.

Other cuestion is that when I built the table, starts to appear a lot of 0 values, maybe because meanwhile the graph is refreshed the table continue recieving data. But I only want real values not 0.

Could anybody help me, maybe there are other ways to do that, but I really don't know them.

Angel

Thank You.

There are peak detect functions in the Analyze->Signal Processing->Time Domain functions. This will take an array of points and return the location and magnitude of all peaks in the array. You have to select threshold and width to suit your data.
