Ken Shirriff shows how to get more out of your Rigol oscilloscope:
A Rigol oscilloscope has a USB output, allowing you to control it with a computer and perform additional processing externally. I was inspired by Cibo Mahto’s article Controlling a Rigol oscilloscope using Linux and Python, and came up with some new Python oscilloscope hacks: super-zoomable graphs, generating a spectrogram, analyzing an IR signal, and dumping an oscilloscope trace as a WAV file. The key techniques I illustrate are connecting to the oscilloscope with Windows, accessing a megabyte of data with Long Memory, and performing analysis on the data.

1 GS/s Digital Storage Oscilloscope + Extras – DS1052E – The ultimate debugging tool for electronics, this oscilloscope will turn you into a “Circuit Whisperer”. You will be able to peer into the workings of your circuits to better understand them. Difficult problems will suddenly become trivial. We tried many beginner oscilloscopes and found this one to be a perfect balance of price and function: it’s perfect as a ‘first scope’ or as a hacker-space resource to share. (read more)
