Search Time (DOCSIS 4.0 Downstream)
trace is the resampled and time adjusted input data (Raw Main Time) used to perform frame search. The amount of data included in the Search Time is specified by the Search Length parameter. The start of the Search Time trace is set to the trigger location (which corresponds to 0 seconds in Raw Main Time), however the time scale is shifted such that 0 seconds corresponds to the start of the preamble symbol.
VSA signal flow
Search Time trace is the resampled time corrected input data before frame search, see the Digital Demodulation Block Diagram for more information.
