I've used the $400-or-so Rigol model (I forget the number), the interface is a bit clunky as one might expect with all the menus and features, but it works well. The "traditional" scopes only go to 8 bits, or maybe 12 bits at the most. As always, look carefully at the specs.
A lower cost alternative to AP (you can get older models used, but they're still expensive) is QuantAsylum, which makes several connect-to-PC-through-USB boxes, notably for high-quality (16 bit or greater) audio is the QA401: https://quantasylum.com/ I suggest reading this whole thread, which started about when the company did, before buying: http://www.diyaudio.com/forums/equipment-tools/231401-quantasylum-qa400-qa401.html On Tue, Mar 7, 2017 at 2:08 PM, Govinda Ram Pingali <govind...@gmail.com> wrote: > This may be a bit overkill for what you are looking for but since you > mentioned you'd like "invest", I'm putting this forward: > > Audio Precision (https://www.ap.com/) > > They make analog data acquisition hardware and a companion software > application, specifically meant for testing audio devices.
