JYE Tech DSO 062 quick review
play work with electronic assemblies, an oscilloscope will soon become a useful tool, if not a necessary one. However, you may not have to spend a lot of money in a professional oscilloscope, a basic tool may be adequate. And that's the case of the oscilloscope I'll talk about, DSO 062 from JYE Tech.
DSO 062 is a DIY digital oscilloscope. DIY because you'll have to solder components and assemble the casing yourself. The main advantage of this oscilloscope is that it's not expensive : I had to pay less than 60 $ to get it. Once delivered, you get in the box the same items than in the photo below.
Asembly is easy, even for a soldering beginner. Surface mount components are already in place, you'll just have through hole components to solder (connectors, switches, capacitors and diod). You just have to be careful, and work for two little hours.
Depending where you buy the oscilloscope, you may not have assembly notes within the package. You can download them on JYE Tech website : Assembly notes (all useful documents — assembly notes, operating instructions, etc. — are on the webpage linked at the beginning of this post).

Using DSO 062
DSO 062 is a well balanced feature / price digital oscilloscope. It doesn't provide a giant display, is a single channel oscilloscope and doesn't provide a great analog bandwidth, but it's good enough for simple electronic assemblies. If you want to power it with batteries, you'll get a good portable oscilloscope.
On interface side, the oscilloscope provides signal management switches (position, time intervals, trigger level, etc.), base sensitivity selectors (0V / div — 0.1V / div — 1V / div) and related multiplicator (x1 — x2 — x5), and display selector (AC — DC — Frequency meter). Switches are reactives (except maybe for vertical and horizontal positioning), same for their related actions.
On signal synchronization, DSO 062 provides it's own trigger signal, or may use an external one. You'll be able to set voltage trigger level.

Use of the oscilloscope with PiZyPwm :
Even if this oscilloscope can't compete with professional ones (and it's not its goal), its cheap price allow the user to come into the wonderful world of digital oscilloscopes without the need to sell its house, spouse and children (and he will play with a soldering iron). So, for a DIY hobbyist, this may be a nice present.
