Monitoring of Vertical Interval Test Signals

Charles W. Rhodes

Vertical Interval Test Signals (VITS) permit continuous quality control of television signals. Principal test signals used are the multiburst, modulated stairstep and sine-squared pulse and bar. VITS are monitored on a waveform monitor especially designed for this application. Such monitors must have a line selector and a positive-acting field selector. A number of the major design factors in the development of suitable waveform monitors are considered. While VITS provide many important measurements, there are some limitations.
