| Abstract: | The HDMI technology is growing rapidly with faster and faster data transmission.At the same time,the high-speed connection of HDMI is also facing a greater challenge than before.The impedance of HDMI high speed differential bus can be good measured by the TDR technology.The TDR equipment can measure the impedance continuity performance of PCB traces、connectors and cables by a very intuitive view.The TDR is playing a very important role in reliability and stability of HDMI high-speed connection system. |
