Here is a link to an instrument (CGR-101) that I purchased a few years ago.
The equipment is manufactured in Toronto.

The software is open source and can be used with Linux, Windows or Mac.
I have found this product to be extremely useful and versatile.
All of the required components will fit in a laptop case.
