Extracting amplitude & phase data

Postby 5string » Fri Aug 18, 2017 2:56 pm

Hello everyone. I am new to these forums. The company I work for recently purchased a 2000 series scope for measuring low frequency signals - amplitude and phase (sinusoidal wave forms). Is there a way to extract the p-p value (and phase) and copy it into an Excel spread sheet automatically (automate)? Any information is appreciated.

Cheers!

Welcome, 5string!

Do you always know the frequency of the signal you are trying to measure?

I am measuring the following frequencies: 1, 2, 4, 8, 10, 20, 30, 60, 100, 125, 250, 315 & 700Hz

I also measure amplitude. These values are inserted in an Excel spreadsheet which uses some formulas to display the filter response in a graph.

It sounds like what you're doing is frequency response analysis. Have you considered using FRA4PicoScope (https://bitbucket.org/hexamer/fra4picoscope/wiki/Home)?

It does export CSV data. But it currently only does a log frequency sweep - so no option to choose specific frequencies.
