【Upgraded Model with 10X Prode] Digital Oscilloscope DSO152, Handheld Portable Automotive Oscilloscope with 2.8 inch TFT, 2.5MS/s High Sampling Rate, 200KHz Bandwidth

To be absolutely clear and up front this is not a laboratory spect'd piece of test equipment. That being said it is a hoot to operate and my Ham Radio related uses are well within the scope of this little gem. So, my two thumbs are up, and I would certainly recommend this device without hesitation.

So, let me preface this by saying that I have two other DSOs, one a picoscope 2204a (two channel) and the other a picoscope 4425a (four channel). This fills a need for me to have with me to do some rudimentary testing where the full power of the picoscope is not needed.Sometimes, you just need to verify that a signal is present, no need to correlate that signal with others. For what I paid ($30), this blows away anything else in this price range. Setting up and using the scope is not easy to figure out, but hook it up to a signal generator and try the different settings until you get a readable output. Sure, it's lightweight, with a rechargeable battery, and you wouldn't want to drop it on concrete from a height, but it does the job. I'm going to keep this one in my toolbox that goes everywhere with me.

I bought this DSO-152 for the sole purpose of testing out the electricity from my home and new portable generator. The unit performed great as in the picture showing me the frequency, voltage and status of my pure sine. For the price, size and features of the unit, it would be a great tool for the hobbyist for other projects. Very easy to use after I watched several youtube videos. Packaging and delivery of the product was top notch. Thank You Westo Giant.

I did not expect this to actually work as well as it does for the price. I was expecting to be able to get a ballpark of frequency signals but after calibrating the 10x probe and watching a video or two on how to set this specific unit up, I'm more than happy with it as a mobile scope. It obviously doesn't have the bells and whistles that a $300+ scope would have, no signal generator or else, but for the beginner hobbyist or someone who needs a quick and dirty look in the field on the cheap, this does what it is supposed to do.

This scope is a very good value for the money. I have used it to test AC and DC circuits and it is a joy to work with, once you get used to its simple interface. The manual says "Progress according to the 1-2-5 way" in the Vertical Sensitivity and the Time base range specs. I was not familiar with this phrase so I emailed them at [email protected]. They explained for the Time base it means 1ms, 2ms, 5ms,10ms. Now I know.They only thing I don't like is the Time Base is fixed and not variable and has no fine tuning. This means it is often not possible to view a complete single waveform cycle on the horizontally timeline, for example a 60 Hz sine wave as shown in the images.Depending on the TIme Base you choose, you will get only part of a complete waveform (see Image One 1mS timebase) or more than one waveform (see Image Two 2mS timebase). Analog scopes have a Variable Time Base that allows for viewing a complete single waveform (see Image Three).BTW - I asked FNIRSI is they sell digital scope with a variable Time Base, or means of viewing a complete single waveform. They replied that no, none of their digital scopes have a variable Time Base. I am surprised about that. Other than this one feature - this FNIRSI DSO152 digital oscilloscope is well worth the money!

Functional but for instructions. Better off buying a unit more expensive and better made.

Monitoring wave forms on a music synthesizers. It works really well.

it's nice to have a small pocket-able scope but this is just too limited for modern use. If you are working on 40 year old equipment perhaps you could find a use for it, but anything more modern I just don't see it. even for me in the ham radio hobby, I cannot find a use for it.
