向高清晰度（HD）和3G-SDI的转换可以是一个平滑的过程，但是您在设计或规划系统设施的初期就应当按照良好的工程实践来进行。在这篇应用文章中，我们为您讲述了在向HD转换的过程中您必须注意的一些问题。Physical Layer Testing of 3G-SDI and HD-SDI Serial Digital Signals Application Note The transition to high definition (HD) and 3 Gb/s will be transmitted easily and successfully. During SDI (Serial Digital Interface) can be executed installation, simple test and measurement smoothly if careful engineering practices are followed procedures should be carried out to ensure the in the initial stages of planning the facility. Selection performance of each link and ensure that each of the correct type of cable appropriate for the piece of equipment performs to its specification. A high data rates of HD and 3 Gb/s signals is critical waveform monitor with Eye and Jitter measurement to ensuring a quality installation. Careful installation, capabi……
