Overview

This module is part of the electronic time base correction system. Its primary function is to measure the timebase error and provide coarse (TANG-ER) and fine (BURST-ER) correction control signals to module H. To  give the required accuracy, error measurement is made at two levels of precision. The CV-TBM signal is coming from the ETBC-B module (H) and is the composite video signal for measuring the timebase error.
