FNIRSI 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

All functions worked as expected... Dso worked perfectly, dds worked (shown in the picture)

Value for money. Got 3 of them together. It’s easy to use and is of best quality. Delivery was before time. Thank you seller for such amazing product.

hi! The product is good but this connector tip is broken, please help us out on this issue.... got to know while using the device.......

only meter has been delivered and no accessories packed

OK. I needed an inexpensive scope for occasional audio repair & field work. You need to have adapters to use the scope with standard BNC probe & gnd. connectors. The tester on the front panel I'm surprised is accurate for transitor/diode/res readings. Was unable to use the scope portion as there is a package needed with the probe & grd. lug to adapt BNC to the mini input connectors. The company said Amazon was responsible for any missing items as the shipper. Amazon insisted Fnirsi should provide missing items. To keep drama to a minimum I am returning the item as defective while Amazon ships me a replacement that hopefully has all I need to use the scope. Will add to my review when I receive a complete unit. Really hated returning it as the semiconductor front panel test portion was very accurate & hoping the replacement is equally accurate. OK so I returned the unit that was missing certain items & just received the replacement DSO-TC3. It had all the items that were missing from my original order. I give the front panel semiconductor test a try & am impressed by the accuracy & ease of use. As an added bonus I didn't know it also had an infra-red device tester that not only verifies if the TV or stereo remote is working but also gives you all the codes. I give this a 5star plus for these features. I haven't tested the scope probe yet but I'm sure it'll work fine within it's parameters. Good for audio but may not for RF work but then again it's specs weren't designed for those frequencies. Overall I am very satisfied & would recommend this for anyone who tinkers with electronics. This device does quite a bit for it's modest price.

I bought this unit to replace a very cheap clone DSO-150 oscilloscope I've had for a number of years. The DSO-150 was an adequate hobbyist scope, but it needed an external 9V power supply and had no additional functions beyond the scope itself. The DSO-TC3 is an ideal tool for the hobbyist; it has a basic single-channel oscilloscope, a signal generator, and a component tester, all in a small, well-made package powered by a rechargeable battery. Operation is fairly intuitive, and anyone learning about electronics or dabbling in microcontrollers will appreciate how helpful the information this tool provides can be. I'd love to have a $$$$ Siglent scope, but out in the field, troubleshooting a flow meter pulse output to a high-speed counter module, I was happy to have the small hand-held DSO-TC3; it performed well and provided all the info I needed to resolve the issue. The 10x probe setting increases the scope's 40V maximum to 400V, so you can stick it in AC outlets or on dimmer switch outputs for a fun (and possibly painful) learning experience. It's not perfect; the scope trace can be a little jittery and some reviewers complain about suspect capacitor values from the component tester, but for the price, it's a really good multipurpose tool. The firmware version in the unit I received is V0.3, which appears to be the latest release at this time.

i'm an auto electrician, unfortunately the output signal skips/ hiccups and doesn't produce a clean and controlled signal. as im testing some delicate gauges and sensors i cannot risk using this item for its intended purpose. seller has refunded me the full cost of the item after requesting a refund.

buen producto, cumple con lo necesario para mediciones a nivel principiante de electrónica
