DSO-TC3 Oscilloscope - 3-in-1 Handheld Oscilloscope & DDS Signal Generator & Transistor Tester, 500Khz Bandwidth 10MSa/s Sampling Rate, 6 Types of Waveforms, Transistors Measure

I got this for troubleshooting my jeep's electronics, it works great for that, but it occurred to me that if I had access to one of these when I first learned about electrcicity and electronics, wow. So if you have a child wanting to learn more about electronics, hard to say no to this price.. it won't do much inside a computer's high speed components, but demo-sort of project kits to do small scale electronic things this would be everything you could want. You can go hard core, get a Raspberry Pi with an expansion card and make your own peripheral and this would still be quite useful.

Good price, easy to use and helped me learn some basics. Thank you.

This oscilloscope is packed full of features for what you pay for it. The main point of having one is the scope. Although the scope is not full of features, it will give you a general idea of what is going on. The function generator is nice to have also, although I never used one. The nicest feature in my opinion is the transistor tester. I like how you simply plug in the three leads and press the test button to see what type it is and some general parameters of the component. I haven't tested a new component and compared the results to the data sheet so I don't know exactly how accurate it is. The unit is just handy to have in your bag in case you need it and don't want to carry a full fledged scope.

I checked its accuracy immediately and its better than 1% compared to my fluke multimeter. Survived being dropped twice already without a dent. Very quick and intuitive to adjust. Very bright… easiest meter to read that I own, despite size. Can’t wait for a two channel version, but one channel is great for 90% of my needs.

I use this for Model Railroad Digital Command & Control analysis. With goal to make use of Raspberry Pi and Arduino automation of trains.I also will be using it with my Amateur Radio hobby. The hand held form factor is extremely handy.

The signal generator and oscilloscope are nice to have occasionally, but my main purpose for this is a component tester. Unfortunately it's near useless for testing transistors. More often than not it will say a transistor is a capacitor, resistor or inductor. Since it does that, can I even trust what it says once it recognizes a transistor?Now it won't even calibrate. I short the leads and it does nothing. Beyond frustrating!Pic 1 - won't calibrate when leads are shortedPics 2-4 - Same KSA992 transistor reads as a capacitor, a different capacitor and a resistor when leads are rearranged. Once it even measured as a NPN transistor even though KSA992 are PNP! Worthless

Great for car audio and in general very happy with it .use daily at work

This really does a lot. It has functions beyond the oscilloscope I bought it for. Love the color display. Would have liked a less than 20mv scale on the scope, but it is a personal choice.

Ordered it for my Dad. He is a electrical engineer and uses such instruments on a daily basis. So far it’s been over 6 months and this product is working well. He is happy with the quality and the price he got it for.

I bought this mainly for the component tester, the oscilloscope was a bonus and it works well in my limited testing. The component tester is great for testing parts removed from circuit boards, and it has worked exactly as I expected.

While generally good and seems to function as described, it's a disappointment that the generator and oscilloscope don't work at the same time. This was an unexpected limitation. While the oscilloscope is working the generator does output a constant 1Khz square wave at about 3V, but it's not changeable and the impedance is undefined. Perhaps that was asking too much of such a small and cheap tool. Still, 4 stars for now.

Works as advertised. Handy gadget for non critical work.

Works well. Auto works well.
