I am so fed up with this. First my resistors go on fire, then my LEDs don't work. And now? My oscilloscope is broken?
Electronics aren't beginner friendly, please all help is appreciated. what am I doing wrong this time?

I just want to display some wave forms but I can’t get anything to display. Is this repairable or am I just missing something obvious?
I was given this oscilloscope couple of weeks ago are they still serviceable as I dare not plug it in just it case it goes with a bang lol
hello everyone , i have this Agilent oscilloscope and i am running an experiment about quantum random number generator , i have two photomultiplier tubes connected to an oscilloscope and i want the collected analog signal be converted to binary 1's and 0's.
how can i make this happen ? and please if there is anything not understood in my post let me know.
Cam across this scope in a thrift store. Priced right at $2.00. Seemed fair. Took it home and went onto the Hankek website where I not only found the drivers for Windows 10 but also the application software that runs the scope. Fired it up and it works! Limited bandwidth but for the few times that I need a scope should work out just fine!!!
Apologies for the mess. I'm just beginning to set up shop in my basement. So I'm a total beginner and I started to buy some equipment to get into vintage and high end audio repair(hopefully). I purchased these used and it seems like things are working? It will be a while until I really dig into them and calibrate the oscilloscope, if need be. But I'm just really excited about it and wanted to share, I suppose.
I recently bought a Philips PM 3267 oscilloscope which was stated to be in working condition. It worked fine but a few minutes after plugging it in, I noticed a burning/smoky smell, no actual smoke though. I ran it for about 15-20 minutes total after first getting it and unplugged it once I confirmed the smell was actually the oscilloscope and not in my head lol. No issues during that time. Ended up getting a partial refund from the vendor.
I’m assuming a bad RIFA capacitor is the likely culprit. However I almost no experience with electronics repair (no equipment either). Would it be worth it to fix if I took it to a shop? What would the costs be? Would this be something the average electronics repair shop could work on? I know some specialty shops in my area but they charge a $150 bench fee just to take a look/diagnose the issue. I was mainly using it as an audio visualizer to accompany my turntable setup.
Hello everyone, I found an old oscilloscope in my attic and don't know anything about it, or oscilloscopes in general. I don't know how, why, or what I need to use it, and I'm afraid to turn it on to find out if it works in case it's a fire hazard or something (probably an unfounded fear but better safe than sorry.) Can anyone give me any advice or tips? I've always looked at oscilloscope and thought "man that thing looks cool," but now that I've actually found one I feel a bit like a caveman seeing fire for the first time. Thanks!
Hey guys,
new here but I hope it's the right place to ask.
Initially I was in the market for a arbitrary waveform generator and eyed the Siglents (SDG2042X with license "upgrade" or SDG3082X). I currently run a Tektronix 2235 and I'm happy with it, does all I need, no laggy or buggy interface and buttons/knobs I can actually remember, but...
Then I noticed that the Rigol MHO934 ("upgraded" to MHO98 specs) that goes for less than 1k, has a 2 channel 100MHz arbitrary waveform generator integrated and, well I don't need a 1GHz scope, but if I get it for a few bucks on top of a waveform generator, I wouldn't say no.
So my question is, how does the integrated waveform generator of the MHO98 compare to, say a Siglent SDG3082X? Am I missing something or is this a crazy good deal? I mean, no I don't need a 1GHz scope (or a digital scope for that matter) but it would be a cool toy nonetheless.
Probably a stupid question but would be grateful for a helpful answer.
Hi there,
I want to measure the output ripple from a buck converter I designed. I watched an EEVBlog video on how to measure power supply ripple, and I was thinking I would adapt it for my use case.
However, the video suggests using a differential probe and measuring it that way, but I don't want to spend a few hundred bucks to buy a differential probe.
I then had an idea, which I want some advice on its credibility.
My main idea is that the ripple from the power supply would be transferred into the output from the buck. So if I subtract the power supply ripple, it would cancel out?
Hi folks,
I need to buy a digital oscilloscope. I was considering a Analog discovery 3, but it is really expensive. It is more than 300 euros. I have been looking for alternatives, like the picoscope. I also considered buying a hantek oscilloscope. I have several questions:
Thanks!!
Recently I had a Rigol scope fail me. Need another jhst for hobby, nothing fancy. Should I buy ADS814A (3.000,00 local currency) vs DHO814 (5.500,00 local currency)? Their spec is almost the same. Is OWON so bad? Is Rigol so goddly? Thanks!
