Abstract:
1. An apparatus for measuring a transmitter and antenna system time delay (TAD) between a given cadence sync point and a known data pattern, comprising: a first plurality of signal conditioning units for sequentially conditioning a multi-bit input digital signal containing an initial cadence sync; a second plurality of signal conditioning units; a multiplexer interposed between said first and second plurality of signal conditioning units; a data pattern source storing the known data pattern selected to provide an unambiguous peak in a time domain, the known data pattern being inserted into a data frame at a known position of the data frame independent of a field sync of said digital signal by said multiplexer; and a time domain measurement device following said first and second signal conditioning units that receives said cadence sync and the unambiguous peak provided by said known data pattern in the time domain and measures the time delay there between.
