Oscilloscope Bandwidth Question

It seems like I can get by with a lot less than I thought. What would be the bare minimum I need to do this kind of work ?

Have a look at the Digilent Analog Discovery; it is pleasingly small and capable. Being connected to a computer means you have to be careful about grond connections (especially when looking at power supplies). Using an isolating probe is the correct way to solve that issue.
magic:
I would like a device like the AD but with some 100MHz IN, 50MHz OUT bandwidth to better cover the bandwidth of new opamps and jellybean BJTs.
Also, for signals within audio bandwidth, you can't beat the resolution and distortion of a good 24b/192kHz soundcard (ESI Juli@, ASUS Xonar STX, whatever else is hot these days) without going all out and getting a dedicated audio analyzer. Buying the AD for THD measurement at 1kHz makes as much sense as using it to test stability of fast opamps or discrete stages :P
You may also go to diyaudio.com and ask people there what they use. It's a more audio-oriented forum than here, go figure.
jlam:
I have the audio range covered I already have multichannel 192Khz interface with 16 In and 16 Out.
Two Mytek 8x192’s
Gyro:
That would have been worth mentioning earlier. :-\
Time to ask a mod to lock your other thread.
