Abstract

The signal generator generates sinusoidal output signals (UR, US, UT, IR, IS, IT) and is advantageously used as three-phase generator for calibrating electricity meters. A number generator (10 to 16) controlled by a clock generator (37) cyclically generates for each output signal (UR, US, UT, IR, IS, IT) binary coded phase step signals (Ph) which are transformed into binary coded instantaneous-value signals by a function generator (17) and into an analog signal by one or more digital/analog converters (18). Each output signal (UR, US, UT, IR, IS, IT) is associated with a sample/hold circuit (19 to 24) which are cyclically clocked by a clock distributor (38). The number generator is formed by angle input elements (10, 11), a switch (12), an adding element (14) and an accumulator (16). A reference voltage input (39) of the digital/analog converter (18) can be connected to at least two adjustable reference voltage sources via a controlled multiple changeover switch. An rms-value measuring instrument connected to amplifiers (31 to 36) controls the reference voltage sources and a phase angle measuring instrument controls the angle input element (10).
