This post was last edited by fsyicheng on 2018-7-31 23:12 I was planning to buy an oscilloscope on Taobao recently. I found an oscilloscope brand and happened to encounter an event, so I bought one to try. The key is that this event is a group purchase. It is the first time to buy a group purchase on Taobao. Through the group purchase, I also met an electronics enthusiast from another province. Double win. I have been hesitating about what model and brand to buy, but the basic models of Mai Ke products are very cost-effective, so I want to recommend it to you. Before continuing, I would like to use my length of service in this forum to declare that I have no business relationship with this company. Now I am their customer, that's all. The model I bought is 202A, which should be a bandwidth of 200 and two channels. The event was actually in the 2-digit range. This price should be a killer for many manufacturers. In addition, it has a 10.1-inch display screen, which is considered a portable design, and a 90M memory depth. These are all relatively high-end things. So I placed an order immediately. After a day of express delivery, I received it this morning. I opened it and powered it on immediately. I won't say anything more. Here are the pictures.
Compared with our own 9.7-inch screen, the display effect is very good, mainly because it is large and clear. In addition, there are no traditional buttons, and the size and overall aesthetics have been improved. But then again, without knobs and buttons, sometimes I really feel that I don't have the opportunity to twist them when I feel itchy. In addition, the advantage of a large screen is that it is better for analyzing data.
In the picture, the blue is the graph saved in the oscilloscope, and the yellow is the real-time data, which can be directly compared synchronously. Then there are many trigger functions, which are essential for oscilloscopes. I won't say more, but they are selected on the screen. Then I browsed their system function part
From these data, there should be several combined modules inside, and the design should be software upgradeable. In fact, the most attractive thing about this product is the 90M storage depth, which is not available on many instruments at a friendly price. So this is worth supporting domestic products, and these entrepreneurial buddies are worth supporting. Although this function is available, I haven't had time to try it today. Finally, I tried some stability and some functions, and gave them some suggestions. I guess this model is also relatively new or not their mainstream model, because the friends who formed a group with me need to ship tomorrow, and their machines are still on the assembly line, so I think there are still some places that need to be improved and perfected. Usually, when posting here, what everyone wants to see most is probably to see the disassembly. I also told them that I should be able to disassemble it after buying it. They said that disassembly is a bit complicated, but this should not affect my enthusiasm. However, after browsing it, there are indeed no screw positions. I saw some disassembly cases on the Internet before, which may be related to them, so before disassembling it, I also have to ask them for a treasure book, although I didn't think about the warranty. This kind of instrument is generally of poor quality when the warranty is broken, and it is useless to repair it. It is generally unlucky and encounters a problem machine. In addition, they have several other machines that feel more mature than this one. I also told them to borrow it or buy another one for comparison. After all, I think this brand is still a bit surprising or expected, but the one I have must be upgraded. The night is dark, don't ask me when to disassemble the machine, as long as your cheering child is a little bigger, I can still sleep.
