147
The Tektronix 147 is an NTSC signal generator introduced in 1971.
It generates multiburst, linearity, flat field, field sq wave, window, sin² pulse and bar, composite and noise signals. The generated signals are available as Full Field Composite Video test signals on one output, and as Vertical Interval Test Signals (VITS) inserted into the vertical blanking interval of an incoming composite video signal, appearing in combined form on another output.
