REES52 DSO138 2.4" TFT 1Msps Assembled Digital Oscilloscope Kit with Acrylic Case

The unit is well-made, except the slide switches which can be sketchy. The box is a puzzle to assemble, but looks great when you are done. The unit is not even close to being a piece of test equipment, but is great to attach to a system to monitor it. I have an application generating a sweeping sine wave at 18 kHz. This unit shows massive crossover distortion at the zero line, whereas my Tektronix does not. That is OK. I am just monitoring the signal, and I know to ignore the artifact. A great buy for the price, and gives a more complete reading than a meter.

Merchant says this artifact is expected (normal). Also, high distortion on higher-amplitude input -- not clipping, but waveform distortion.

Really good scope for this price but I need more capability and planned to have Hantek USB. But for the folks who are looking for monitoring duty cycle ans signals like Arduino this is best. And finally thanks for Amazon for accepting return.

It ia a Toy type O-Scope . Good for learning the wave forms & it's types / paterns . 1 MHz sampeling rate , whereas I didn't get a proper record for a 21 KHz signal . The cover case will come un-assimbled .

It is NOT assembled product. It is in KIT form and you need to do LOTS of soldering.

Assembling case was hard, should have put some instructions in paper. Also one part was broken but I managed anyway. Glassy case looks great when finished. No complain on oscilloscope.

I needed a DSO for a basic microcontroller i/o signal testing at an affordable price and came across this product. Lots of reviews and videos are available and most are positively favoring this device, so I went ahead and purchased it. I'm glad I did. It may not be 100% accurate but serves my purpose. I don't have to write test-specific code now to test high-frequency signals as I can directly see the output waveform which is a big help. The device needs 9V power supply. I'm very happy with the packaging by the seller, it kept the product completely secure during transit. A big plus was the included acrylic case. Some seller sell this DSO without the case, but it is a must-have, so get it along with the product. For the price of Rs. 2200 this has turned out to be one of my best investments as far as test tools go.
