На видео представлено сравнение режимов AVTO для ZOYI ZT-703S и FNIRSI 2C23T. Для анализа использовался простенький генератор частот на CD4060.

Вот эти комплектные щупы черные у ZT-703s плохие. Я щуп с 703s подключил к генератору fnirsi 1c15, и наоборот. И у 703-го были сбои в атонастройке, а 1с15 - нет. А когда я щуп с 1c15 подключил к 703-му, режим авто стал отрабатывать четко. Так что я заказал два таких же щупа как у 1c15. У него маркировка P6100 100Mhz. Видел другие обзоры где режим авто на 702 или 703-м тупил, и всегда были эти черные щупы.

@@user-oi7hz9jx8r да, читал про это. Пробовал менять (у меня несколько щупов было и до этих налодонников). Особой разницы не заметил. Чёрные плохие если компенсация не на штекере а непосредственно на рукоядке щупа (и такой у меня есть).

It's strange why Fnirsi doesn't trigger at the beginning of the signal when you transfer the signal from 7.18 kHz to 28 Hz. 0:26 around The triggering bug occurs at 10x setting and a signal greater than 3.6Vpp, at 1x setting at 1.5Vpp signal. Based on my tests so far, the Zoyi pair is much more usable than the Fnirsi. I have the 1013D, DPOX180H and the latest 2C53P. All are disasters. 1013D is not capable of what was written in its parameters. DPOX180H Can be used, but occasionally I have to check with my Owon HDS272s. I bought 2C53P because I thought it would get better after DPOX, but I was wrong, it's just as bad as 1013/14 and 2C23T. You can't trust it, the bugs are unlikely to be fixed, based on my experience with Fnirsi so far.. Zoyi is also full of bugs, but at least you can use it. Tigger, which can be seen in your video. The persistence mode is on, so if you move the signal, change the time base, the vertical sensitivity, the signal remains on the display. Frequency measurement is not always good, at 100ns I measured 4MHz instead of 5MHz. But he measured it well in the faster and slower time base next to him. I didn't regret buying the Zoyi, but I did the three Fnirsi, I could have bought a Micsig tablet scope for that much money... I can't see my new comment so

Yes, there are such moments. I showed everything as it is, without editing. But it is worth noting that fnirsi has fewer errors in auto mode. Maybe it's just a feeling I have.

@@bih0use Yesterday I received a ZT-703😁, unfortunately without a battery, and I didn't have a button top. That's why I could only put it together for today. I tried what you presented in the video, I tested it with a Rigol DG912 function generator. Firmware. 1.3.9 I noticed that if the probe is set to 10x and the signal is greater than 3.6Vpp, it cannot trigger at low frequency.🤨 If I measure in 1x, it works fine. There are still many bugs in this device. I have an Owon HDS272 and three types of Fnirsi scopes. 2C53P behaves similarly to 2C23T. What I have managed to find out about it so far is that Fnirsi is not worth buying, because it has a lot of bugs. And unfortunately, most of them will not be fixed. At least Zoyi is dealing with the problem. At least he's trying. At Fnirsi It is not possible to determine the true bandwidth by measuring the rising and, it is not possible to use a single, normal trigger for high frequency signals. There is a certain time base beyond which it does not work faster. Fnirsi knows about it, I was told that it should work like this...😡 I also found a few bugs in Zoyi, but they are not as dangerous as in Fnirsi... In Zoyi, the automatic trigger does not work properly. When I stopped the signal (Single trigger or Hold) and wanted to move the trigger in time (Move, with the arrows to the side), I noticed that it was spinning its memory. I was also surprised that I've been pressing the button for 5 minutes, the signal is moving and I haven't reached the end yet.😵‍💫🤣 For example, when I pressed the left arrow and then pressed the right arrow, the sign moved once in the same direction as when I pressed the left. On the second press, it was already moving in the right direction. When I wanted to measure the rise time of the stopped square signal with the cursor, there were times when the signal also moved. And I'm sure there are quite a few more bug, but I think Zoyi is much more usable than Fnirsi.

А кто из них правильно показывает Vpp?

Zoyi. У фнирси вообще с этим плохо, он даже частоту врет. Из всех бюджетных девайсов только старшие девайсы Zeeweii относительно калиброванные по уровнях сигнала.
