Arbitrary Waveform Generator and Total Distortion Evaluation

The paper design a good performance arbitrary waveform generator with AD's digital-analog chip AD760 as the core. Thesis mainly research hardware and software design of computer-controlled arbitrary waveform generator for the corresponding. Hardware part of the arbitrary waveform generator take Cygnal's high-speed micro-controller C8051F310 micro-controller as the controller and AD760 circuit components of the design. We carried out anti-jamming design when hardware design, Including filtering, spare part handling of input pin, grounded, the power handling. The paper also describes a total distortion of periodic arbitrary waveform definition and evaluation process and methods, the energy is calculated using the time domain distortion, and the influence of the measurement system itself is compensated. This method can be used for arbitrary waveform generator arbitrary waveform distortion for accurate measurement and measurement calibration.
