ABSTRACT:
An electrical waveform generator and a method for electrical waveform generation are provided which includes a central processing unit (13) to first provide sequential points of a selectable waveform in digital form and store them in digital memory (15). A memory controller (14) then generates the waveform by sequencing those points through a digital to analog converter (17). Previous instruments required large memory capacity to handle all of the data points necessary to produce a wide variety of waveforms. The present invention uses mathematical notation to define and store selectable waveforms and calculates the data points when a curve is selected or defined for use. Memory controller (14) uses concatenated looping during the sequencing of points to the converter (17) for the purpose of making the data memory (15) more efficient. The single waveform generator of the present invention may be used in many of the various applications of waveform generators including automated test equipment having industry standard communication buses for control.
