Desired specs/price for a low-cost/beginner's DSO

Hi everyone.

I was hoping you could give me an idea of what you would consider the best specs a PC-based (USB) scope should have. I'm referring to a scope for the hobbyist crowd (Arduino, DIY, etc.). What do you think would be the ideal characteristics and price? Something cheaper than the common Rigol scopes (less than $300). What would be the must-haves? For example: BW, Samps/s, etc.? Something you would recommend to someone looking to get started in electronics but not wanting to spend anywhere near $300.

Thanks.  :-+

I'm not aware of any sub-$300 PC-based scope that can compete with the old used analog scope. I think Dave's rant 'Buy a real analog oscilloscope PLEASE' is still valid. All of the cheap USB-based scopes that I've encountered are still toys. This is not to say there are not some decent products out there. Some people are happy with the Picoscope products, for example. However, the cheapest 2 channel / 25 MHz model (not exactly impressive specs, even for an old analog scope) is already $400. USB-based scopes are also much less versatile than stand-alone scopes, whether digital or analog.

Rigol, Owon and Siglent appear to have some decent entry-level DSOs. Below that, you have the used analog scopes.

Some specs I would consider essential: 2 channels, 50 MHz bandwidth, 500 MS/s sampling rate, 10kpoints memory, vertical range from 5 mV/div to 5V/div, good software. This would have to be substantially cheaper than a real DSO, say $200 max.

The Hantek DSO-2150 that I've bought in 2008 costs now $180. You can have the DSO-2090 for $150.

Start by beating these devices.

DSO-2150 specs are as follows: 60MHz 150MSa/s 64K

Best regards

Thanks, that's more or less what I was looking for answer-wise. I'm asking for the ideal specs of a cheap, beginner's, hobbyist scope. Even if such a product doesn't exist, what you would like to see in one (for these sort of people, not pros like most people on here). I know analog scopes are better and all that, but I'm talking about people who aren't going to need that much horsepower in their equipment.

Thanks again.
