Function generator for generating three-phase signals on e.g. electrical field, has digital-to-analog circuit provided with output channels that are connected with memory unit, where memory unit is provided with waveform display function

摘要

The generator has an electronic circuit provided with a digital-to-analog (D/A) conversion circuit that is controlled by a program. Output channels of the D/A conversion circuit are connected with a computer memory unit, where complex data of harmonic components is entered in the memory unit. The computer memory unit is provided with a waveform display function. Current lines (IR, IS, IT) are formed corresponding to the harmonic components and provided with fundamental frequency data. A memory circuit processes harmonic phasor voltage three phase signals and intensity in network transducers.
