Hi there! I'm a student looking for an oscilloscope, and onviously they're too expensive for me. I thought about getting an old broken one and fixing it, of course my dumbss didn't think about the fact that people who own oscilloscopes most probably know how to fix them, probably even better than i do. So i thought about getting an old one and of course they're considered "vintage". So i haven't found anything viable yet and i came here to ask if there are some insider websites or tricks to get oscilloscopes for a price that is reasonable being a student. Thank you very much!
Hi there, I've gotten to electronics pretty recently and have played with a few 555 timers and many logic ICs, I'm also following Ben Eater's 8 bit computer series and am planning to make my own version of it too.
The thing is, often times when I'm trying certain stuff out, I have to sort of imagine what my circuit is doing. I don't really 'see' what's happening and I feel like being able to see how the voltage changes over time would be really helpful to me. I'd like to be able to see things such as switch bouncing and how quickly a signal transitions from low to high.
However, oscilloscopes are pretty expensive. And after doing some research online it seems that having a bench oscilloscope is much more fulfilling. I can totally understand that, but I'd like to know if it would be worth it for me specifically. I'm a Computer Science student so it's not like this is going to be super relevant in my future, but I'm still super interested.
I understand that logic analyzers are good when dealing with digital circuits, but I want to be able to see analog stuff too. And since I want to observe bouncing and transitions I guess that means I'm looking for something that works at high frequencies(?) I'm hoping to observe stuff in the range of 20us-50ns.
Can anyone guide me in making a decision that would be best for me? I'm afraid that if I buy a bench scope, it would be amazing, but what if I don't use it to it's full potential and it ends up being a waste of money?
What I have in mind at the moment:
- USB scope: Hantek 6022BL
- Bench scope: Rigol DS1054Z
Tl;dr: want a scope to observe bouncing/transitions/high-speed-stuff(?), CS background but still interested in analog stuff, worried that I might not fully utilize bench scope if I get one
For a university project, I recently needed a device able to sample and record the digital signal coming out of an IR receiver, a photodiode to bre precise. Not having an oscilloscope, I decided to build my own by using an ESP32, and it turned out so good that I decided to share it as a standalone project, in case anyone like me will be in need :)
In practice, I exploit both the cores for running concurrent processes and run-length encoding for efficiently buffering and sending the data over the serial port. Finally, a simple Python script helps to visualize the result.
Here it is: https://github.com/davidedellagiustina/esp32-oscilloscope
Exactly what the title says. I wanted a comprehensive list of all of them, free, paid, all their features, and some basic benchmarking. It's here: https://www.composinggloves.com/ossiloscope-comparrison. Links to everything are right in the database. Was a bit of a pain to track down some of these but I am very happy with the result. Had no idea so many free options existed.
EE student here, looking for a scope recommendation. I've read hundreds of EEVBlog posts, sub posts and lists and can't seem to find a decent handheld or USB scope on a budget. I bought a Hantek 6022BE to fill in the void but I found the software to be utter crap and I somehow missed the fact that it doesn't even have AC coupling.
The main reason for USB or handheld is that I'm living in a dorm and moving a bit between dorm and home. Just looking for decent specs for audio range for now, with some room for expansion to faster signals in the future.
With so many decent chinese multimeters I'm considering getting a Hantek or Owon handheld or maybe even the Miniware one (but the user interface seems pretty crowded) but I'm hesitant because I can't find many reviews on those.
I'd appreciate any pointers, otherwise I'll just go with the standard 1054z.
I am trying to understand how I can create an oscilloscope in Touch.
I am trying to use one of the Arduino Mega's analog inputs to pass a signal from a modular synth system into TouchDesigner. I know I can do it easily with an audio interface, but is it possible to do it with an Arduino?
I managed to get the data inside of TouchDesigner but the sample rate is really low (Baud Rate is currently at 230400).
For example a slow LFO input looks good like this:
A good looking low rate sine wave generated from an analog LFO coming through the Arduino into TD.
Now I am assuming that my problem is that I am using the Trail Chop, which is super slow because when i increase the rate of the LFO the same sine wave looks like this:
Not a good looking sine wave :(
What I probably need is to use another Chop instead of the Trail that reads the incoming data much faster, at a sample rate that is close to the audio's rate like below:
Sample rate of 735 samples per frame.
The Trail Chop has only 1 sample per frame, what can I use instead of it to get a higher sample rate for my Serial data input coming from the Arduino ?
EDIT: FOUND SOLUTION (but with other issues):
So I managed to get closer to what I need by:
- Adding the Maximum Lines in the Serial DAT
- Getting rid of the Select Chop that selected only 1 channel
- Adding a Shuffle CHOP and Sequence All Channels
This is how the network looks like now:

With the waveform expressed nicely like the oscilloscope:
But unfortunately I am getting these unwanted spikes:
I have been told that this is due to the limitations of the ADC of the Arduino. Can anyone elaborate on thi

I don't really know more than that... but I want to learn more. I've done lots of coding projects and Arduino projects, but I've never used an oscilloscope and want to learn how. I was thinking about investing between $350-$500 and found the following scopes:
Siglent SDS1104X-E -- $499 4 channels 100 mhz
Siglent SDS1202X-E -- $379 2 channels 200 mhz
I really wanna learn more about designing complex electronics and feel that this would be a worthwhile investment. Are there any other options I should look into? Is it worth getting 4 channels with lower frequency vs. 2 channels with higher frequency?
I've been looking to get an oscilloscope but their prices change so drastically given the bandwidth they support. I haven't been able to find a clear explanation as to how many MHz oscilloscope do I need. I usually work with ARM embedded boards with SoCs clocked at 1.5GHz. Does that mean I need an Oscilloscope with the bandwidth that matches the processor clock speed? 😧 Please explain in detail if someone can. Thank you.
For the time being I plan to work on MCU with clock speeds <= 80MHz. I'm ashamed to admit but there is something about nyquist theory that I cant rap my head around (pun intended).
Im looking for a scope that would be perfect for the MCU mentioned above, I'm a poor man so the cheaper the better.
So i recently got this oscilloscope, works fine and all. BUT... as soon as you flick on the mains switch it starts emitting a constant, high pitched noise (as seen in the second picture below). The previous owner told me that he didnt have that problem. Im thinking its the psu interfering with the mains harmonics, or maybe even the tube itself.

I have wanted an oscilloscope for a while, both for general electronics use and for automotive use. I have been told I can probably inherit one of the ones at my work as they aren't used often any more, but I'm unsure which would suit me best. The options are:
Tektronix THS720P, Fluke 97 and Fluke 123
These are all older machines but with very low use and in generally good condition. All come with 2 channels and all the probes and charger etc. The tektronix one is oldest and has a few light scratches on the screen but is a good brand, the Fluke 97 seems in good condition overall and the Fluke 123 is newest and almost unused but doesn't have a cursor function.
Any thoughts on which is best?
Hey, I have the chance to get a Tektronix TDS10002 for 225. Is this worth it? Just looking for a hobby scope that can last a good bit.
What oscilloscopes do you use to check your mix? is Live ever gonna release an oscilloscope like the Bitwig? Live is so versatile but still and I don't seem to find any M4L devices good enough for the job. Something with sidechain options would help..
I am considering getting a scope to go alongside my logic analyser. I can generally fish one out of stores for projects in the office, but this is more faff when working at home. And it would be nice to have my own unit anyway.
There seems to be a myriad of devices. Something up to 100MHz would most likely be sufficient for my projects; at least 2 channels; large display for my failing eyesight; mixed-signals capabilities useful but not essential. Not sure what other features might be good to have. I was hoping for something solid and reliable in the sub-500 GBP range. Can push the boat out pretty far if necessary, so that's just a guideline.
Thanks in advance for any advice.
