Abstract

The VHF and UHF tuners are separate units, and each is manufactured and tested by itself. In the television instrument they are electrically interconnected and, in effect, comprise a three band, all channel, varactor tuner. In those instruments using the electromechanical channel selection system, the two units are mounted together with brackets and interconnections so as to provide a single V-U unit. In those instruments featuring the digital direct address system, each tuner is mounted on its associated address system module.
