PURPOSE:To obtain a test signal generator suitable for a high sharpness television receiver by providing a means storing a pattern section and a frame waveform pattern forming means. CONSTITUTION:A pattern section storage means 25 stores plural pattern sections representing a selected part of a frame waveform pattern from a patten ROM38. Then a frame waveform pattern forming means 44 retrieves the stored pattern sections and forms a series of pattern sections representing the entire frame in a real time by repeating (or storing) the pattern sections in a prescribed order. This series of pattern sections is converted into a test signal by converting means 14A-14D and 16A-16D. The test signal generator suitable for a high sharpness television receiver is obtained in this way.
