DollaTek DSO152 Portable Handheld Digital Oscilloscope 200KHz Bandwidth, 2.5MS/s High Sampling Rate with PWM Output

This is a great little scope for the money. Yes, there's only one channel and the bandwidth is low, but for basic troubleshooting it's excellent. I use it at a repair café where tools need to be portable. The fact that it isn't earthed, unlike a mains-powered scope, is a great advantage when probing power supplies, which sometimes seems to be 90% of our work.

For the price this is excellent. As long as you don't expect too much, for general checking and testing this is a neat, small and effective bit of kit. Very clear screen, parameters well displayed - or not as desired - and wide range of speeds and sensitivity. Does maybe 80% of the tasks that my "big" scope does.Highly recommended.

If you're after a cheap scope that has very basic functions and you're not overly worried about accuracy, this is a great product.My only criticism is it's yet another Chinese device with a built in lithium battery, I hate these things because cheap lithium cells have a tendency to explode and I'd rather have to put a couple of batteries in the unit that I know are good than rely on some random unbranded likely unprotected li-po cell.

This little device replaced my large oscilloscope.I'm using it for car audio installations, to check for clipping, distortion and set gains on amplifiersVery nice and portable

I have two CRT oscilloscopes but they are so big ! This works flawlessly and is accurate, definition is adequate and is less important because frequency, voltage and duty cycle are displayed, excellent A+

I bought this scope to visualise signals from my modular synthesizer. It is really easy to use and versatile and perfectly suitable for this purpose. Crisp, easy to read display. Great tool to visualise waveforms and envelopes etc.

Great piece of kit, simple to operate, for the cost well worth the money, used on a number of portable generates to ensure the power was stable

Complete novice but this tool worked exactly what I needed it for, setting gains on my amplifier and finding clipping points on the head unit.Perfect, job done.
