Not sure what you mean by that. I have a Rigol DS1074Z oscilloscope, and there were official upgrade packages offered at eye watering prices to activate extra features in the scope. Features like decoding and displaying the signals on SPI and I2C busses, or increasing the sampling speed and getting more memory. However, these seem to be unavailable these days. There was a very long thread on a site discussing this where people published hacks to activate this. But I felt it wasn't worth the risk of bricking my scope for, so I never bothered.
There is also a way to control the oscilloscope from a python script running on your computer, I did try some experiments with this, and it worked well.
That URL doesn't exist, but turns up a lot of foobar2000 stuff which I am not sure is the same thing. A lot of .eu web sites from the UK were forced to close by the EU as part of the Brexit process. Anyway "foo" is a favorite Linux word for "just any random thing", like a variable or function.
