The target parameters may be the same, and the performance can meet the parameters, but the over-limit performance is incomparable.

The main thing we encountered was that the indicators were a bit vague.

If the indicators are false, it means they are unqualified. You don't know how much they will be false, which will be a major problem after mass production.

Yes, you should keep your eyes open when buying and try it out in advance.

However, we often encounter the problem of fake products. When testing, we choose the good ones, and the mass-produced ones will not work.

Haha ~ Maybe, but big manufacturers are more careful about their reputation and have their own strict standards. Generally speaking, they won't do that. For example, our power amplifiers are free to try. If you have no problem using them, just keep them. There will be no problem of sending you a new one and then running it in again.

The problem with domestic chips is that the testing standards are too low. The same product may vary greatly from batch to batch, or even from batch to batch.

As for the chip problem, I can only sigh. The chip problem has not been solved yet, but I believe there will always be a good solution in the future. Come on for domestic chips! ~

Big companies are much better. They also have false labels, but they are not as exaggerated.

That's right, we make instruments, and we can't fool people with the parameters.
