3 Summary

In summary, RP198 was the only SMPTE specification discussing 3G and HD pathological specifications. At the SD data rate, there is not a defined dc wander limit. There is test equipment capable of generating in excess of 150mV dc wander at SD. SMPTE specifies a maximum of 50mV dc wander for all rates – other than the SD rate. The 12G SDI pathological pattern is manually created. LMH1239/1229 is the latest generation of the long reach cable equalizer designed to support 12G and lower rates of pathological video pattern including the SD pathological video pattern with an excess of 150mV dc wander.
