Are these scopes any good for synth work?
Basically just want to view wave forms and such.
Something like this:
https://www.amazon.com/dp/B00SXVUETU/ref=sspa_dk_detail_1?psc=1

Says it bandwidth is 1Mhz.
starthief
I have one like that but cheaper, with a single trace, and it was okayish. A bit noisy, not necessarily easy to read voltages or calibrate, needed frequent recharging over USB, touch interface was a bit rough.

I really prefer Jones O'Tool.

I got the DSO202, but I don't like the "touch screen"

if you don't need the two channels I think you'd be better off with a DSO138

https://www.amazon.com/AUTOUTLET-Assembled-Oscilloscope-Digital-Acryli c/dp/B07BSKL44Z/ref=sr_1_4?s=industrial&ie=UTF8&qid=1530639009&sr=1-4& keywords=dso138

it's cheaper and the reaction on frequency changes is faster

I don't need the additional features the 202 has.

If you got enough space and a bit of luck, you could get a used cathode ray oscilloscope for less than 100$
starthief
Having two or more channels is really useful IMHO. You can compare "before/after" signals, among other things.
acidblue
After shopping around a bit, I think I might get a Pico scope instead.
Much better sample rate and bandwidth is 10Mhz.

I’ve got that exact model of picosope, and it’s great for synth work. Sometimes I wish I had four channels instead of two, but overall it’s incredible value. And all picoscope models use the same software, so you get a lot of advanced tools even with the entry-level scope.
Futuresound
Excuse my ignorance, is it possible to get 3.5mm adapters for scopes like these, to allow patching directly in and out of them?
ranix
I have a moderately high opinion of SainSmart but have not used this device.

Yeah Futuresound you can. Worst case you can cut the probe cable and cut a 3.5mm TS cord and connect them together. But if you get a scope with a good connector you can usually get a 3.5mm or 1/4" connector to anything cable. That one has an mcx cable. You could do mxc->bnc, then bnc->3.5mm if you have to

just bought one of these from ebay for £89

seems to work fine for basic wave viewing

Thanks ranix!

I like the look of DATA and Ben (DivKid) uses it to great effect in his videos. Price is a bit of a put off though, for me, and I'd rather not have something like that in my case.

The Pico products look interesting though... Might have a proper look at what they are about smile
mckenic
Sorry if this is outside the 'scope' (ha ha see what I did there?) of what the OP is looking for but any time small scopes are mentioned I cant help but jump to the thought of Gabotronics scopes!

Have two and LOVE them. Pop em in a plastic pedal enclosure and Bobs your mothers brother!

I bought the Pico Scope I posted above, not the DSO in the original post
It arrives Friday, much better deal IMO, only $39 more and way more
functionality and bandwidth.
Cant wait hyper
ranix
I have a few of the xminilab and xprotolab scopes and they are very good.

You made my day... thanks a lot for the link.

I have a DSO150. while it works but it's not quick or comfortable to use. battery holder is external to the case which is pain in the axx. well, can't complain for the price! no comparison to o'tool plus, tho Dead Banana

2nd for the DATA. Chris from LearningModular.com uses it extensively as well in his videos. Great tool form learning modular and working with new modules.

modules that are Eurorack.

Here is a guide for a $26 oscillator if you just want to look at waveforms: https://aisynthesis.com/cheap-eurorack-oscilloscope/

I wouldn't recommend it for serious work.
I have a Tektronix on the bench that I use for testing, and in the rack I have a Mordax data which I absolutely love, but I also use it a lot for testing prototypes in the rack.

Did it arrive yet? I would love to hear how it works.

If there’s anything you’d like to know about it, I’ve got the same model scope.

Slightly related to this, but what are everyone´s experiences with software-based oscilloscopes?!

My Laptop is sitting less than 1m away from my modular, and with all the inputs and outputs I have readily available, I keep thinking that spending 100€-200€ on a semi-decent oscilloscope might be just another case of G.A.S. when I could just use the powerful computational machine that is my PC right next to everything razz

Any good software oscilloscopes?

I never see anyone really use these, maybe because they don´t look good on youtube or because of the extra editing you´d have to do? wink

Or am I missing some super basic point on why PCs "cannot do" the job just the same?
hamildad
the motu 828 MkII that you are selling has an oscilloscope and a spectrograph in the tools section of the software.

not sure how bad /good it is, but as MOTU is DC coupled, it should be ok for low freq working.
xenosapien
yes, good point - I still do have (& will keep) a MOTU Ultralite mk4, that has the same software utilities.
I just don´t like that particular one, aesthetically. (yeah yeah I know meh )

But you just reminded me of a key point -> DC coupled !

Yeah, that should mean every other (VST-based maybe) Oscilloscope software should work just fine.

Thanks!
