Does anyone know if something like this would be a good Oscilloscope?






The user interface on a device that small is always terrible. As an example, would you enjoy using a calculator the size of a quarter?

1MHz is very low for a modern bandwidth. I've got a scope from the early 60s that is faster. There is no AC coupling. The input jacks will break within a few months of heavy use. Input impedance is half of what the standard is. I could go on.

Look on ebay. You can get a quality 20MHz dual channel scope for $50 second-hand.
 
I agree that input/probe connector just looks like it wants to go south really quick, I would invest in something more substantial unless you just have nothing better to do with your change :whistle:

Like Cyparagon said look for something used on eBay that is guaranteed not to be DOA but cheap.

Good luck...
 
First determine whether you really need the oscilloscope. I got one and thought I'd use it more, but it really isn't worth what I spent on it (Rigol) for the amount of time I use it. You might be better off spending it on a nice multimeter or soldering station.

very true, im not sure if I would even use one that often or even have a real use for it.
 
I´m having the DSO201 with a custom firmware. It´s quite ok for low frequencies, measurements at a car or to check a audio amplifier but for lasers it could be used as a graphical LPM with a modified firmware.

The only benefit is, it´s quite handy and portable. So when you are often doing some measurements outdoors, it´s useful but at home you better go for a real scope.

Regarding the DSO301, also sold as DSO504
The signal display area is 299 X 199 and contrary to advertisements, the only captured signal is what fits in the window at time of capture.
The actual sampling rate is up to 20.8 MSa/S but the amplifier has a wide bandwidth so if your signal has components above 10 MHz you will have aliasing.
The maximum sensitivity is .1V/div but it is noisy, .2V/div is the practical limit.
The input resistance is around 540K so it won't work with probes that assume 1M.
If these limits are not a problem, it is a nice portable scope, or a system component.

After writing the above I discovered that for firmware V3.2 sweep rates below 100 ms/div (which is when you most need storage) gives highly distorted, probably overflow while averaging.
