Traditional RF leakage test systems leverage downstream signal sources that typically emanate from the headend/hub today. In a high-split architecture the 108 MHz to 137 MHz aeronautical band is now in the upstream path! How can we measure upstream leakage? DOCSIS 3.1 cable modems can be commanded by the CMTS to generate target OFDMA upstream data profile (OUDP) signals and an updated RF leakage meter can be used to accurately measure this narrow portion of the OFDMA upstream carrier. How will this work?
