Description

technical field [0001] The invention relates to the field of electronic technology signal generating devices, in particular to an arbitrary waveform editing method and device. Background technique [0002] A signal generator is a device used to simulate real signal output. With the development of electronic technology, it has gradually evolved from a signal generating device with a single function, such as a sine wave generator and a pulse generator, to a multi-functional All-in-one multifunctional device. At present, general signal generators can generate sine signals, square waves, pulse waves, triangle waves, noise and built-in arbitrary waves. No matter how many built-in waveforms there are, they are always limited, and the waveforms required by the user are not necessarily included in the limited set of built-in waveforms, thus a new requirement is put forward - the user can arbitrarily determine the shape of the signal according to the needs. In order to meet this de...

Problems solved by technology

However, this method mainly has the following shortcomings: the ordinate corresponds to the DAC code value during the editing process, which is a digital quantity, while the output is an analog quantity (voltage), so when the user sets the DAC code value of the starting point and the ending point, he needs to calculate it by himself What is the corresponding voltage, it is not intuitive and inconvenient, and the processing speed is very slow
