It's a cheap scope with some limitations : It's not a real 100Mhz scope, the firmware is has some flaws and missing features, especially when saving samples (it's olny a screen choot). It can be useful on low frequency electronic works like Arduino,... My probe doesn't seems to work very well, hopefully I have another one. Some people are working to make a better firmware https://www.eevblog.com/forum/projects/reverse-engineering-fnirsi-5012h/ Some videos about this miniscope https://www.youtube.com/watch?v=SIH48bIUU00 https://www.youtube.com/watch?v=kTDefglaPOo
Timing measurements are good but voltage level measurements are not accurate with an error increasing with the range selected (refer to photos to see the error). For example when measuring a 5V DC source errors are 0% at 1V range, 2.4% at 2V range, 4% at 5V range, 8% at 10V range. When measuring a 10V DC source errors are 0.8% ate 2V range, 2% at 5V range, 8% at 10V range. These errors are not dependent on probe attenuation. Is it a bad quality of all the DANIU ADS5012H or only mine ?
Shipping/Delivery: I chose the Brazil Direct Mail option, the product arrived in 24 working days, stayed only 4 days at customs and did not have to pay any fees, not even R$15 of postal dispatch, For the Brazil Direct Mail freight is exempt from this charge (DICA PRECIOSA). The packaging arrived in good condition. Product/Operating: The product and its accessories arrived in perfect condition, there were some scratches on the screen, but there is a protective film (virtually invisible) on the screen that can be removed. The screen of the device has an intense brightness and quite sharp colors, the user interface is quite friendly, intuitive and easy to operate. The apparatus has very good accuracy in time/frequency scale and reasonable accuracy in voltage scale. In its operation there are some flaws: 1- The trigger function in the Auto mode works well, as NORMAL and SINGLE modes do not work as they should (they are practically useless) which makes it very difficult to use the device to analyze non-periodic digital signals. 2- The voltage scale "200mV in 1x" and "2V in 10x" has serious problems (as can be seen in photos). 3- V-RMS and V-AVG measurements are unreliable, the V-RMS is simply calculated by VPP / 2Ö2 in any waveform, which is completely wrong as this is valid only for perfect senoids, V-AVG is made in a similar way. Other considerations: I missed the cursor function very much, something extremely useful and, in my view, something simple to implement because it is purely software. The apparatus is very limited in the matter of zooming and displacement on the horizontal axis (time axis), this combined with a problematic trigger makes it almost impossible to use this apparatus to analyze non-periodic signals. I mentioned above all the negatives I found, however there are many positives that have not been cited, at the end of the day I am still impressed with the quality of this product in relation to its price. I don't regret the purchase.
Very nice! Thanks banggood.. :)
muito bom brasil
Very good product
Hi everybody! Delivery was in time, but the parcel was not so well protected... it was a simple box which during the shipping got a rupture in the upper left corner - see picture 1. Fortunately the oscilloscope is well protected in his little black bag and suffered no injuries.. see the rest of the pictures. It looks great. About the performance, what can I say... I know all the reviews of EEV Blog, the quest to make a new/ much better firmware through reverse engineering by Ataradov... BUT even if it's a 50MHz oscilloscope, for my 60 EUR payment and my needs, it is a very good TOOL !!! Tks Banggood, wrap up the parcel better next time!
otimo produto,gostei muito.a entrega foi rapida.
sell and good I indicate product arrived right
Nice pocket scope. I can't test BW fully, but to 60MHz sine it looks ok. Can't comment too much on accuracy, but its near enough for my needs. I can use desk scope if I am really serious. Rechargeable battery makes it handy. Screen has scratch marks straight out the box, a disappointment. Cheap MM's have better QC. I'll still give it a 5.
