tdr test equipment

The next-door King has already talked about the principle of TDR and how to determine the TDR resolution. So, we have to correctly measure the circuit impedance on the PCB board, and what needs to be noted?1, the impedance Test industry standardsHave posted a lot of impedance test pictures, re-paste a picture for every

Certificate: The file installed on the computer cer , only the computer with the certificate installed, can do the real machine debugging2.APP ID: Is the application Bundle ID , each application has a unique Bundle ID , but we do not need to

Optical Fiber Network Fault Test Equipment Analysis In recent years, as people have higher and higher requirements on the rate of broadband, because the performance of optical fiber is better than that of copper cable, it has been widely used in the backbone construction of broadband projects. At the same time, due to the increasing coverage of optical fibers, fiber failure detection is becoming more and m

As the core connection device of an enterprise network, a vswitch has the primary performance standard to ensure the speed of the enterprise network. At present, enterprises have launched various Ethernet switches. Many parameter performances are marked by manufacturers themselves. These performance parameters differ from the actual situation of switches. Hardware Network Tester The manufacturer must not exaggerate the virtual parameters of a product because the industry has the same

With the huge development of the Internet, network devices are indispensable. network devices have become the cornerstone of Internet development. With the development of the IT industry, many network equipment providers are no longer focusing on this piece of cake. They have extended their tentacles and become more and more extensive: this is why cloud computing, smart phones, and the Internet of Things (IOT) are eager for talent, and the recruitment

I. Overview: QQ Group of a Netizen consulted three places through the MSTP line 22 interconnection, are Cisco equipment, but one of them does not support OSPF, ask if the normal situation, the data to go 8M line, but the 8M link problems when the 4M backup link, and then use GNS3 to build the environment test a bit, Brush up on the SLA settings. Two. Basic ideas: A. Static routing priority dynamic OSPF r
