DDS 120 works fine with Windows 10
Despite the instructions being for Windows 8, 7 and even earlier versions, the software works fine with Widows 10 and the driver installed automatically. The instructions are terribly unclear and need major improvement. The included software is for both DDS 120 and DDS 140 and that becomes only clear upon careful examination of the software. For laptops without a disc drive, it is necessary to first transfer the software to another medium. It would be much smarter if the software came on a USB flash drive. But other than that, it is a wonderful product.Read full review

The little scilloscope that could
Got the unit and set it up with a Dell e4300 laptop. It checked out with my Heath Kit Oscilloscope calibrator. I really like that it did all the math and you could save the information.
I decided to use it to check out a suspected full bridge rectifier from a welder so that I could compare the saved video with a known good rectifier. It was set up to check the DC out put from the rectifier into a load while the input AC was controlled. Using a DSO-138 oscilloscope to make sure everything was safe and the out put was a nasty looking DC at five volts., I put the probe on 10x, attached the ground to negative and touched the positive output. There was a little hiss inside the DDS-120 and it became a nice little paper weight.
What can I say. There must have been a load somewhere even though the laptop was not plugged into AC. Send it back? Not me. I am sticking with the little DSO-138, do the math, and make drawings.
My opinion is that the five volts input max allows too much room for error. And there is no protection. Even though I was set up for 50 volts with the probe, I missed something and even if I could get it repaired, I would not be comfortable using it. Good for some that really know all the tricks to look for, but not good for this old farmer.
Update. Went inside the DDS-120's box and took a look. Nothing seemed burnt. Hooked it back up to the laptop and guess what? It began to work! Used it to check a circuit board with the 1mv test signal and it worked just fine. If you are looking for something to work with low voltage, this will do fine for the DIY experimenter. Also, it seems to have more than one life..Read full review

A well made product
I am using this for hobby diagnostics of electronic circuits and find the hardware and software to be of good quality and easy to use and understand. I have used it a few times so far and have nothing negative to say about it. I does everything which I expect it to.Read full review

PC based scope review
This is a good entry level scope. It provides basic functions and allows you to view digital circuits effectively. It lacks the ability to precisely set voltage ranges and time. It also tends to drift off sync. For the price it is what it is, a decent value scope that provides a waveform view into your process. one bonus is that it allows you to record and playback the waveform captures.Read full review

Perfect scope for small projects
This oscilloscope has all the features I need for all my home electronic projects. It is very well worth the price. I'm a retired Electrical Engineer and have experience with all the name brand scopes costing 100s times the price of this little device. I use the SainSmart DDS120 all the time, I'm very happy with it.Read full review

On my first use....
I found this item to be a great value that is accurate, reliable, and very affordable. I am well pleased with the SainSmart DDS120 Pro Oscilloscope.

Good value
Compact, inexpensive, reasonable bandwidth, and high quality test leads all combine to make this an excellent choice for a general purpose oscilloscope.
