Excellent oscilloscope, performs almost all the functions of a bench oscilloscope, but is portable. Great cost benefit.

Excelente osciloscópio, realiza praticamente todas as funções de um osciloscópio de bancada, porém sendo portátil. Ótimo custo beneficio.

Fast shipping from China in 8 days. The arrived oscilloscope has a different internal hardware and less powerful than the one on the website. It has a nice case, USB C connector and video output as an upgrade but it doesn't get to 120MHz and the waveform display is not as stable as the one in Youtube video. The maximum displayable frequency is about 90 MHz and then at 100MHz it goes to almost zero and above 100MHz you see the aliasing effect, from this we deduce that the real time sampling is 200Msa/s. The previous model had a sampling rate of 250Msa/s. The 500Msa/s advertised for the previous model, if true, are for periodic signals only and the new model could have 400Msa/s. The firmware is 1.2.6B, trying to upgrade it to 1.2.7 from "hardware version mismatch" error. Hopefully they will make the correct firmware available. The input attenuator is not frequency compensated so, depending on the flow rate, the frequency response changes. It goes from -3dB to 50/60MHz on 500mV and up to +3/4dB to 80/90MHz on 200mV to 10mV. This also highlights that it does not have an antialiasing filter. The other features are pretty much what you see in the reviews and videos on Youtube. In practice, even with less powerful hardware, the waveform is displayed is clean and stable up to a few MHz, it is acceptable for sine signals up to 30/40Mhz and about 10MHz for square waves, above the possible errors allow only a coarse analysis of the signal. However, it has a minimum sensitivity of 10mV which is better than similar models and, knowing its limits, can be used for field verification of many types of signals. For example, I can check the presence of the signal of an oscillator or a clock up to the frequency limit visible by the oscilloscope, bearing in mind that at higher frequencies the measurement is less precise.

Spedizione veloce dalla Cina in 8 giorni. L'oscilloscopio arrivato ha un  hardware interno differente e meno potente di quello sul sito internet. Ha una bella custodia, il connettore USB C e l'uscita video come upgrade ma non arriva a 120MHz e la visualizzazione delle forme d'onda non è stabile come quello nel video Youtube. La massima frequenza visualizzabile è circa 90 MHz e poi a 100MHz va a quasi zero e sopra i 100MHz si vede l'effetto aliasing, da questo si deduce che il campionamento real time è 200Msa/s. Il modello precedente aveva una frequenza di campionamento di 250Msa/s. I 500Msa/s pubblicizzati per il modello precedente, se sono veri, sono solo per segnali periodici e il nuovo modello potrebbe avere 400Msa/s. Il firmware è 1.2.6B, tentando di aggiornarlo a 1.2.7 da errore "hardware version mismatch". Speriamo che rendano disponibile il firmware corretto. L'attenuatore di ingresso non è compensato in frequenza per cui, a seconda della portata, cambia la risposta in frequenza, va da -3dB a 50/60MHz su portate da 500mV in su a + 3/4dB a 80/90 MHz  sulle portate da 200mV a 10mV. Questo evidenzia anche che non ha un filtro antialiasing. Le altre caratteristiche sono più o meno quelle che si vedono nelle recensioni e video su Youtube . In pratica, anche con un hardware meno potente, la forma d'onda è visualizzataè in modo pulito e stabile fino a qualche MHz, è accettabile per segnali sinusoidali fino a 30/40Mhz e circa 10MHz per le onde quadre , sopra i possibili errori consentono solo un'analisi grossolana del segnale. Comunque ha una sensibilità minima di 10mV che è meglio dei modelli simili e, conoscendo i suoi limiti, si può usare per la verifica sul campo di molti tipi di segnali. Per esempio posso verificare la presenza del segnale di un oscillatore o di un  clock fino al limite di frequenza visualizzabile dall'oscilloscopio tenendo presente che alle frequenze più alte la misura è meno precisa.

It hasn't been possible to test it yet. When it occurs, I'll post my evaluation.

ainda não foi possível testa-lo. Quando ocorrer postarei a minha avaliação .
