c bits s: dealing with special snowflake ADCs is annoying. 20-bit output range? yeah that won't be annoying at all

yeah a 100MHz scope would be solid for that. make sure your probes don't have shitass bandwidth though; that's what's been biting me lately (albeit at higher frequencies - 50 MHz signals into 100 MHz probes on a 500 MHz scope look like rear end). various forms of logic analyzers and things like that are nice but not as mandatory as just a working scope imo

the aforementioned logic thing that plugs into a computer (saleaeaea whatever) looks awesome and is pretty cheap depending on your bandwidth and channel count needs

Oscilloscopes enable time domain visualization of electrical signals. The more you spend, the finer the time domain detail you can see. You can see both voltages and currents. Fancy models can do Fancy things, like frequency domain analysis or other complex maths.

Also ten megs on a breadboard is going to be fine, your tenth order harmonics are still more than a meter and the parasitics will be irrelevant

hobbesmaster posted:well if you have long looping wires you're making antennas which needless to say is bad Which, at 10 mhz, need to be nearly a meter in length to be relevant to your tenth order harmonic (which is pretty dang irrelevant, you can get by just fine with like less than fifth order)

Back in school we built an arm7 system on a solderless breadboard with like memory buses and poo poo running all over the place and those effects were by far the least of our issues

If 10x your frequency is still long relative to whatever you're doing, then nothing matters

Mr Dog posted:that's pretty cool It's not so much hard as just expensive. With stuff like that you have to start caring about impedance controlled traces and that generally means lots of layers and things like termination and now you've got an eight layer board with bga components and microvias and that poo poo sucks at least at a hobbyist level Although for what you're looking for I dunno something like tis new m4s could work maybe? Tm4c I think?

i prefer diff probes and low-ohm resistors because current clamps tend to suck rear end for milli and microamp measurements
