| 文檔介紹：These parameters are affected by the cable length, that over longer runs of cable will introduce amplitude and frequency losses to the signal resulting in longer rise and fall times of the signal. Overshoot and undershoot are typically a result of incorrectly termi nated devices or panels which introduce reflections into the signal. Additionally deformation of the cable can also introduce reflections into the signal along with cable loss. Active devices may introduce jitter into the signal as the signal is processed or genlocked to a reference signal. The first stage of troubleshooting a physica l layer issue is to verify the link by using CRC (Cyclic Redundancy Code) words to verify the link is error free. The Video Session display will shows statistics of the CRC Errors. | |
