Abstract

The invention discloses a novel computer oscilloscope which is orderly connected to a signal conditioning circuit, a master control circuit, and a PC machine. The signal conditioning circuit has an input signal interface. The master control circuit comprises a signal processing circuit and an analog to digital converter. The signal conditioning circuit carries out filtering, attenuation/amplification and level shift processing on an input signal. The analog to digital converter converts a processed signal into a digital signal. An oscilloscope display screen is a PC machine display screen. Through a simple circuit structure, the function of the oscilloscope can be realized, the novel computer oscilloscope has the advantages of high working stability, high reliability, no obvious waveform distortion, a high measurement frequency, a small volume and low cost, and thus the novel computer oscilloscope has a wide application value.

Description

technical field [0001] The invention relates to the technical field of oscilloscopes, more specifically, the invention is a novel computer oscilloscope. Background technique [0002] For traditional oscilloscopes, they are divided into analog oscilloscopes and digital oscilloscopes according to the difference in signal processing. Traditional analog oscilloscopes have single functions and are bulky; while digital oscilloscopes are more powerful, but their maintenance and system upgrade costs are high, and it is difficult to popularize them in teaching and training. Moreover, the existing oscilloscope does not have a corresponding PC interface, so it is difficult to collect, analyze and process data. In addition, traditional oscilloscopes are relatively bulky, which increases the development cost of the oscilloscope. [0003] Therefore, how to break through the research and development bottleneck of traditional oscilloscopes, how to facilitate the acquisition and analysis o...
