I bought a small DSO201 to use outdoors.... The battery lasts forever and the operation is good I'm well pleased with it.

Downside!!!! The menu is kinda "side scrolling" So to change anything ie vert / horiz resolution, trigger, volts/div etc.. must be separately selected before adjustment!! No big problem though!

Love it!

Further on down the advert it also clearly states that it is not supplied with a case.
I got a Plexiglas case from Ebay for mine. That is also where I got the scope. Think I only paid around $18 for the both of them. #### DrG ##### Active Member I bought this one. I think it has already been mentioned. Here is the User Manual. Some assembly was required (no trouble). Yes, you should look carefully at the specifications. You can probably find it a bit cheaper (I think I paid less than$26 for it either on sale or with some coupon or something). I did not have to upgrade the firmware as I had the most current version.

I like to "pride" myself on not buying more expensive things until I have "earned" the need and knowledge to use them. That sums up the "why" I bought a toy O-scope. I am happy I did. I have used it more than a few times and it is a useful and convenient tool, in my view. The more I use it, the more I become aware of its limitations and that is actually the expected positive result, which will, likely, lead to a future purchase of a "real" O-scope. That is my thinking and review.

it depends on what you are doing with it. a coworker was using a digital scope, trying to diagnose an audio amplifier that was drawing excessive current, but not so excessive that it tripped the protection. the DSO he was using appeared to have a half of volt of noise at the speaker output. the waveform on the scope looked like noise similar to that on the square waves in post #5 above. connecting an analog scope revealed that it wasn't noise, but a 1Mhz oscillation in the output stage of the amplifier.

I got mine from Ebay, but it shipped from the US a couple of $more but the instructions were in English. But then I've had it for a while so price might be higher now. #### Nigel Goodwin ##### Super Moderator Most Helpful Member I got mine from Ebay, but it shipped from the US a couple of$ more but the instructions were in English.

They pretty well all come in English, if you get a Chinese one then it's probably a mistake - and if you tell them they will send another. Quite often the pictures on the website show the Chinese version, but it clearly states that an English one will be provided.

This one is not a stand-alone O-scope and it is $29. A board meant to be attached to laptop/desktop. I had been looking into it as a way of using a secondary computer that has given way to a primary and/or an older laptop or tablet. I thought that it had some impressive specs - not sure of that, but it looked that way to me. Decent reviews and open-source are added benefits. #### Nigel Goodwin ##### Super Moderator Most Helpful Member This one is not a stand-alone O-scope and it is$29.

Well at first glance the spec looks pretty poor, particularly the scope scope - however, a longer look considering the extra facilities it provides, means it might be worth a look (something else to play with - I'm tempted now ).

Here's a small scope I've recently bought, it claims to have 30MHz bandwidth, and has internal rechargeable batteries - I haven't had time to play with it yet, apart from switching it on and pressing a few buttons.

The spec looks pretty interesting, and it's nicely portable.

Makes perfect sense.

Is like learning to play golf, you don't go and purchase the most expensive golf clubs available. You can purchase cheap or used ones, and once that you master them, and most important enjoy what you are doing, then you invest on better ones.

EDIT: I can see these inexpensive scopes as excellent tools when you require a "floating" scope, as most can be battery powered.
