That might be iffy for mains, but for low power solid state stuff, it should work. A x10 probe on that 10v input max means you can measure 100v circuit points. And x100 probes are on the market for even larger range.

PC scopes tend to be very limited. Especially their front ends are limited with 200 mV/div as the highest sensitivity. Measuring higher voltages is easily accommodated with an attenuating probe 10x, 100x, 1000x are commonly available. But there is no substitute for a good analog front end. For $250 you could get a pretty nice used Tektronix scope. That would be my choice any day. But hey... Maybe I'm just old fashioned... 🙂

I dunno know, like tomchr says - I bought a Tektronix 2225 (2 channel, 50MHz) on eBay for $100. Granted you don't get waveform capture, but its a real 'scope. Just make sure you get a return policy, but there's a ton of used stuff out there for a lot less $.

Unless you absolutely need the raw data, a digital camera works fine for waveform capture on a real oscilloscope. It's been done that way for decades -- starting with Polaroid film back in the day... Love the old Tek scopes. My 2215 (2-ch, 60 MHz) and 2465B (4-ch, 500 MHz) are still ticking.

what about the RIGOL DS1052E digital scopes? They are just a tad bit more expensive at $400 from hong kong and they seem to have rich functionality. I used old tek analog scopes when i went to school 20 years ago, but i don't know how keen i'm at buying one of those old bricks on ebay. The new scopes smaller footprint is very attractive to me, and i kind of like to have a new scope with warranty over something 15-20 year old which i don't know if i could fix myself if needed.

I use everyday a Tektronix TDS3014 DPO scope at my job, and it is an amazing tool.
For my personal use, i can't buy a 5k$ scope, so i have bought RIGOL scope 2 years ago, a DS1022CD.It is a 2 analog channels 25MHz 400Ms/s, with 16 channels logic analyzer. I had payed it about 500$.
It is a very good value for money !
I highly recommend their products.
(After that, i have also bought the generator and multimeter from Rigol, also
very good products !).

Algar_emi, i really think that "PropScope" is too expensive for what is that.
If you look also for a standalone scope, and if the price is an issue, maybe this product can interest you :
