概要（Overview）

The TEKTRONIX VITS 200 NTSC VITS INSERTER is a high quality signal generator designed for VITS and data insertion into the program signal. It provides three different modes of standby operation in the event of program line failure. The VITS 200 provides a complement of digitally generated test signals, all of which may be inserted as VITS. There is a one-line source identification code (recognizable by the VM700A) which may also be inserted in the vertical interval. There are also four external inputs which will accept other signals or data to insert in the vertical interval.
