Arbitrary waveform generator system

摘要

The waveform generator herein may be used to generate an analog waveform selected from a plurality of stored digital representations of waveforms. These are stored in a memory within a processor section of the system. At least one waveform generator section communicates with the processor section and receives parameter control words therefrom respecting the manner in which a waveform is to be generated. Each such generator section includes a function generator controller, a temporary waveform memory for storing a selected one of the waveforms and a digital-to-analog converter. After receiving the parameter control words from the processor section, the function generator controller operates independently of the processor section for reading the data words stored in the temporary memory and generating the selected analog waveform.
