The pattern generator utilizing a character generator for adjusting the frame size, and color of CRT includes a H/V synchronous circuit (200) for generating H/V synchronous signal, a microcomputer (300) for applying control signal and data to character generator (400) according to the selected pattern by a pattern selecting key (700), a character generator (400) for transmitting R.G.B. signals and video signals by the control signal, a subcarrier generator (600) for transmitting video subcarrier for transmitting the pattern, and a modulator (500) for transmitting the pattern signal after frequency modulation.
