Problems solved by technology

[0005] (1) There are too many buttons on the existing signal source panel, making it difficult for users to operate;
[0006] (2) The existing signal source only displays the signal frequency, not the signal amplitude, and the signal amplitude needs to be measured by an AC millivolt meter;
[0007] (3) The existing signal source does not display the waveform of the signal, and users often need to use an oscilloscope to observe whether the signal waveform is distorted

Abstract

The signal source consists of controller, waveform sampling and processing module, program controlled clock module, frequency measurement and keyboard control module and LCD module. The controller is connected to waveform sampling and processing module, program controlled clock module, frequency measurement and keyboard control module and LCD module respectively. Input signal is inputted to waveform sampling and processing module and frequency measurement module. The program controlled clock module is connected to waveform sampling and processing module. Less key button are placed on panel. Besides frequency, amplitude of signal even waveform of signal can be displayed without need of using oscilloscope.

Description

Technical field: [0001] The invention relates to a measuring device, in particular to a digital signal source with waveform display. Background technique: [0002] In automation equipment and systems, performance testing and information transmission are often required, and these are inseparable from certain waveforms as the basis for testing and transmission. Commonly used waveforms include sine wave, rectangular wave, triangular wave, etc., and the signal source is the instrument used to generate these waveforms. [0003] In engineering practice, a signal source with adjustable frequency and amplitude is often required as a component of electronic equipment, or as an experimental instrument for testing and adjusting electronic equipment. [0004] The existing signal source equipment has the following deficiencies: [0005] (1) There are too many buttons on the existing signal source panel, making it difficult for users to operate; [0006] (2) The existing signal source ...
