How to set up Scalar biofeedback scan without a computer?

The computer is what does all the BFB analysis in any form of BFB Spooky2 performs.
So there is no method to achieve your goals.
The GX generator just takes measurements, and while it has a stand-alone feature, that is a simple no logical application of a frequency list with no dynamic automation or processing behind it. Approximately 90% of what the software can do, stand-alone can not.
The XM has none of the above even and relies on an external device to take measurements which are also plugged into the computer.
