freeware tool to analyse the waveform

Thread Starter


Joined May 15, 2012

I have information of a signal in CSV file format. I would like to plot the waveform and analyse the signal with more cursor lines.

I know that we can use Excel sheet to plot the waveform.
Apart from EXCEL sheet, is there any free software to meet my requirement?

Please suggest the bests.
