Thanks a lot for the oscilloscope and for the new firmware. Still, there is a question concerning time stamp of the saved files. All of them have the same date 22.03.2020. What about the possibility to improve this situation?
My screen went blank, and the screen no longer turns on. I can hear the unit click on, but for some reason the LCD screen is dead. It's only three months old. I tried different 5v 2a power supplies - no change.
Olá, comprei um osciloscópio FNIRSI 1014D, e notei que numa ponta só medir uma bateria 9V só mede a tensão positiva, se eu inverter a polaridade da bateria, ele dá um pulo para baixo e não mede mais a tensão negativa, porque está invertido a polaridade na ponta. Se eu medir com a outra ponta, ocorre o contrário, mede polaridade da bateria do contrário e não mede invertendo. Caramba, que estranho. No meu osciloscópio analógico aqui, com a mesma ponta meço tanto tensão positiva quanto negativa. Aí não sei se é um defeito ou característica. O que será?
Buyer Beware! This scope does not meet its bandwidth or sampling rate specs! Check out reviews on RU-vid channels "learnelectronics" or "Kerry Wong" for more information. Spoiler alert: Instead of 1G Samples/sec, it samples at 200M Samples/sec, and instead of a bandwidth of 100Mhz, its bandwidth is about 30MHz.
Take an adjustable resistor of 10kohm. Now connect generator output wires to both ends of this resitor. At center contact of this resistor you get an adjustable output signal. Simple!
i would like to buy this scope as it has more for much less compared to others but one thing seems to be missing that actualy is on a cheaper tablet scope from FNIRSI that being the ability to self calibrate the probes to the scope I cannot see it on this scope i can get this for 150 euro and will have to pay 50 euros more for a hantek 100mhz with a signal generator So if anyone from FNIRSI can tell me where the self calibration function is ?, I will buy one.
I agree with Yusuf Oylum. It is rubbish, both software and the hardware design stink. Having reverse engineerd the 1013D and compared the two firmwares I can confidently say this about these scopes. And service is non existent. When I bought my 1013D it arrived with a defective touch panel. Trying to repair it resulted in a broken glass panel and FNIRSI did not aide in any way to resolve it. I did get most of my money back from the Aliexpress vendor I bought it from. To get it fixed I turned to reverse engineering the damn thing. Also have a 1014D which was donated to me, so also have insight knowledge on that one.
100 Mhz is bullshit and can measure up to 35 Mhz. Firmware has a lot of issues,bugs etc. You can not receive any mail from company. My both Fnirsi 1014D bricked somehow, does not pass Fnirsi logo. I do not recommend any of these products if company is Fnirsi. Put some money and buy Hantek or Owon.
@@fnirsi been nearly 2 months, device bricked after 2 days of use. I can not use my device that i paid for. Never ever gonna buy anything related to Fnirsi. I sent 2 e mails and no response for 5 weeks..
