With reference to the HDMI spec. ver 1.4a, there is a requirement for HDMI connector to meet impedance specification at 200ps 10%~90% rise time. I would like to know if this is the rise time entering the connector? If so, it will be know as the incident rise time. As such, I would kindly need help on how to establish an incident risetime of 200ps entering the connector because most of the time what we observe on the sampling scope is the reflected rise time. Please correct me if I am wrong.
Your kind advice is very much appreciated. Thank you very much.
This is probably not an Oscilloscope question. It might be a TDR or Network Analyzer question. It might be more properly addressed on an HDMI forum or reflector. I don't follow HDMI, but I'm sure that the information you want is available.
