Cheapie Oscilloscopes
Discussion
Has anyone got one of these sub-£150 oscilloscopes? Are they any good or are they a bit rubbish?

I doubt you get much for £26 but are the more expensive ones worth it?

Depends what you want it for I guess?
I’ve a cheapie 2 channel 100MHz - probably gets absolutely nowhere near 100MHz but is very useful.
The areas where savings are to be made will be bandwidth and memory- a decent buffer for storage is very useful along with decent trigger menu.
The sub £50 automotive ones would be fine for abs signals, crank timing, canbus checks etc but not much more, I doubt they have much storage so are more a ‘live’ monitoring tool.

Picoscope. Spend as much as the freqency/memory you need. https://www.amazon.co.uk/s?k=oscilloscope

Even the 2000 series are great for most things automotive.
It comes in to its own with the software/live decoding for the money.
What do you want it for?
You can do a certain amount with a soundcard, just some software.
I've had one of the 4 channel DSO pocket models for about 10 years, it has its uses, but I mostly prefer an old analogue Tektronix scope I paid about £80 for many years ago..
I expect the market has moved on, but the best answer will be different if you're trying to diagnose say EFI on your car rather than fault find a hifi amp.

Well actually I'm trying to check Wordclock & Black & Burst or TLS reference but it sounds as if it might be worth trying one. Lugging my old Tektronix around on site isn't really practical. I don't need voltmeter functionality & some of the reviews comment that meter response is slow anyway so I was looking at this one:

When you're trying to look at more complex digital signals, triggering a simple becomes an issue.https://www.amazon.co.uk/Oscilloscope-Handheld-Ban...
One of my scopes has a built in circuit to trigger on analogue TV signals for instance.
You may be getting into 'logic analyser' territory or need some add-on hardware or software to extract the signals you want.
