I'm starting my embedded systems course this week and the professor supplied a list of suggested tools for at home use. I was wondering what oscilloscopes you guys use and what I should be considering when picking one out.
I have a Siglent SDS 1202X-E which has two channels and up to a 1 Gs/s sample rate.
I can't find anything about the delay between sampling in Siglent's data sheet , which leads me to believe it does sampling exactly simultaneously.
For context, I am measuring the phase angle between two sinusoidal wave forms and am accounting for all sources of phase error, so if there is a time delay between samples on channel 1 and on channel 2, this will render itself as a phase error that I need to factor into my calibrations.
Hey all. So over the past few years I've gotten into synths and that led to wanting to build one. Ive made guitar pedals, a mixer and a headphone amp from kits so I have soldering experience. But everything was from kits and all plug and play as it were. For Christmas my girlfriend bought me a few as34__ chips and kits of all the components I'd need. Sourcing all the parts separately do I need to have an oscilloscope if I follow the schematics and all the values in them? Without one I know there's no real guarantee that the wave shapes will be exact but beyond that is there really a need for one?
So I've been using Image-Line's Wave Candy when making noises, I love how it simple and works well, but it can't automatically change the update rate or Scroll speed, therefore I'll have to manually change the update.
The visualizer from Vital is very cool though, it could automatically fit the key note so no matter what key I press I could see the wave stay still. But it's for vital only, and it seems there is no VitalFX so that I could use on other synths. Any other recommodations?
Edit: just found this FREE plugin, and it's syncing function is so badass and clean. It's my new favorite oscilloscope now. Well beside the Vital Analyzer though.
I want a free and simple oscilloscope just to view phase issues and sidechain...are there any good ones?
I'm new to eurorack and the first module I acquired is a 'Capt Big-O' VCO. I also bought an espotek labrador oscilloscope board and made a simple patch->pins cable.
I can see a nice waveform when I tune the pitch to around 500Hz, for sine, triangle, square and sawtooth waves. It's also stable around 1000Hz.
However, it changes at other frequencies and looks like sections of another out-of-phase wave are stitched into the dominant wave. I see three small strips, totally maybe a quarter of the wave in the example images I'm linking to.
Is this potentially some kind of artifact of sampling or is it a common observance in VCOs? It's annoying because the artifacts falsely trip the trigger and the scope can't stabilize a view of the wave (unless I'm near 500Hz or 1000Hz). Thank you for reading.

This question always comes to mind but finally I gathered courage to ask. The Arduino has 8bit ADC and the Pi Pico has even better - a 12 bit ADC. However, both Arduino and Pi Pico seems less sensitive than a typical Digital oscilloscope ADC which is, surprisingly 8 bit, but has finer resolution of 1mV or lower. I was wondering why this is so? Why Arduino or Pi Pico ADC could not behave as good (if not better in Pi Pico) voltage resolution than a typical oscilloscope. Thanks.
Update: Thanks you all for replying with explannation. It becomes a bit clear that the ADC embedded inside uC are not very accurate (or very noisy). So I should use an external one. I original plan is to log data for precision meaurement of magnetic field using a microcontroller (1 - 100 sps). so any suggestion on the external ADC module for arduino would be very helpful.
I'll include some pictures to help follow along with what i'm doing. I got my signal generator connected to my oscilloscope. My signal generator is outputting a sin wave with a 1.6V AMPLITUDE. my oscilloscope is getting a voltage rating for the sign wave at around 1.6 V PEAK TO PEAK. I'm curious what the issue is, I don't remember this ever being a problem as ive had these instruments for about half a year now. Interesting how it's exactly half the voltage being read.
Greetings,
I am a engineering student, who just sometimes wants to check how some circuits work and stuff like that, nothing serious. I have found a used INSTEK GDS-820C 2CH 150MHz locally and am wondering if this is still a good option? It's currently listed at 140 Euros (160USD), but could probably lower the price, would be a resonable price to pay?
Thanks!

I have a teensy 4.1 lying around and it seems like a good use for it. I’d rather not write the code if there is something readily available.
Can someone explain this to me like a 5 year old? I feel so bad I don’t understand this but I don’t know what a sweep is. Is it like when the screen resets ?
Hey Guys, while I was fogging around in the lab to find the antenna cable which is connected to the reciver on the roof. I thought of using a oscilloscope to see any signal but all the cables had no signal even the one which was connected to the reciver, why was this like that ?
I'm starting to get deeper into pedal making and circuit design, and I would like to buy myself a device that helps me debug and better understand what I am doing.
I feel an oscilloscope and spectrum analyser with a signal generator would cover it, but I am looking for something good but not too expensive (100 euros range?), that is also not too large. Something that requires connecting to a computer to trade-off size would be OK.
I have little background, so reading specs alone is not necessarily enough for me (ie. I've seen one that covers MF/HF/VHF UHF Input, but that does not ring a bell for me, when it comes to pedals).
What do you folks use and recommend?
So, I have watched this video about nts-1
https://youtu.be/8UDEUoljbCo
And I was wondering how do I connect my nts1 to the PC to use oscilloscope plugin like this?
Okay so for context I have a hantek2d82 model and can get software going on windows. But wanting to make. It work on Linux. Is this something building open-scource would work and if so how would I find out what dependencies I need?
As I understand it, it doesn’t display the waveform at the synth’s output, but rather the output from the most recently played voice, which is then scaled to fit the screen no matter the frequency of the note. Is there a way to get a consistent view of a waveform with an external scope?
So I'm quite new when it comes to measuring currents that are below mA. I have a few devices with deep sleep capabilities, and I want to measure their current over time as well as their current when they wake up and go back to sleep (peaks). Waking up and going back to sleep can take anywhere from 10 milliseconds to 1 second. I want some precise measurements, but that comes at a cost, apparently. The devices usually operate at 3.3v.
I don't own an oscilloscope, but I came across a review from EEVblog about a $70 oscilloscope: https://www.youtube.com/watch?v=SIH48bIUU00
It actually looks decent for the price, which has increased to about $95 on AliExpress since his upload. I haven't touched an oscilloscope since high school, so I'm not sure if it can do what I want.
What would you recommend?
