If you're planning to use a scope for general electronics
troubleshooting, as opposed to merely capturing predictable waveforms,
you would be doing yourself a huge favor to look at the waveform
capture+render rate.
Many cheaper oscilloscopes (and pretty much all USB-only devices) don't
These PicoScopes look pretty cool :]
As it happens I am just now trying to free up some garage space to get an
electronics bench together. But it's coming up on 20 years since I last
soldered and it's a whole different world with scopes now. So thanks for
this thread!
Also if anybody knows good
Hi Remy,
I use the signal generator all the time to calibrate the pot on the
probes when in x10 mode using the square wave output. Note that the
scope runs off USB power so you can't generate very hot signals, it's
+- 2V (USB is 5V), you'll need to make your own external booster
circuit for
hi,
AudioPrecision looks nice but it's way over my budget considering that
it won't be used on a daily basis.
Looking at the specs, the QuantAsylum audio card only seems to have AC
coupling (down to 1.6Hz) and their oscillosccope page is a bit short on
details.
Hacking a soundcard as an
Depending on how cheap and improvised you want to go, and how handy you are
with basic electronics, you can easily adapt your soundcard to work as an
oscilloscope. There are a number of guides on the internet on how to do
this, such as:

Picoscope make the cheapest 16-bit scopes around (USD 1000), the
16-bit stuff from Tektronix is a lot more expensive (USD 31000 -
that's right I didn't accidentally add an extra zero, it's x30 the
price). I would recommend using the Picoscope and use Python's easy c
bindings to call the Picoscope
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
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.

Hi,
I'd like to invest into an USB oscilloscope.
The main purpose is in analog data acquisition and instrumentation.
Since the main purpose is audio, bandwidth is not really an issue, most
models seem to provide 20MHz or much more and I'm mostly interested in
analog inputs, not logical ones.
