The generator is used for reception of harmonious and periodic pressure of the triangular and rectangular form up to 100 k h z in laboratory works at research of the acoustic phenomena, electric circuits of an alternating current with active and reactive loads. The generator should form simultaneously three types of signals: rectangular, triangular and sine wave signals of pressure and provide a choice of one of 6 ranges of frequency. Exact frequency of generation should be provided due to creation of a corresponding operating pressure. 1. Characteristics: 1.1 Overall dimensions of the generator, mm. Length no more than 200. Width no more than 175. Height no more than 60.
