The USB interface is a product that can be seen everywhere in life. Almost every electronic product around you has this little thing, and you can't imagine completing data exchange and instrument control without using a USB. We cannot find such a wide range of applications in electronic devices, digital products, and industrial products as the USB interface. Simply put, our keyboards, mice, printers, digital cameras, mobile phones, etc. must all use a USB interface, which serves as a bridge for communication and data transmission between all electronic products. Therefore, the demand for reliable and fast USB testing solutions in development, design, and production work is increasing day by day and constantly changing. The following are two basic testing items for USB interfaces: stability testing and consistency testing.

Stability testing is directly related to various aspects of the performance of the USB interface, and of course, it is also directly related to hardware material selection. Consistency can be tested through specialized testing companies. Stability testing and consistency measurement are important challenges for manufacturers when developing electronic devices with USB functionality. The reason why products can be labeled with the USB trademark is that they are licensed only after passing very strict stability and consistency tests. To conduct consistency certification project testing, it is necessary to pass the automated USB testing plan established in the USB standard 2.0 specification, and strictly conduct various stability measurement items such as salt spray testing and temperature resistance testing. Different tests verify signal quality, packet delivery, timing parameters between the sender and receiver, receiver sensitivity and other more functions. So the small USB interface is just a testing project, which cannot be underestimated.
