Abstract

The invention discloses a high-accuracy handhold digital oscilloscope which comprises a data collecting circuit, a low-pass filtering circuit, an A / D converter, a data transmission module, a spectral analysis and parameter adjustment circuit, a waveform display circuit and a microprocessor. A signal output end of the data collecting circuit is connected with a signal input end of the low-pass filtering circuit. A signal output end of the low-pass filtering circuit is connected with a signal input end of the A / D converter. A signal output end of the A / D converter is connected with a signal input end of the data transmission module. Signal output ends of the data transmission module are connected with a signal input end of the spectral analysis and parameter adjustment circuit and a signal input end of the waveform display circuit. A signal output end of the spectral analysis and parameter adjustment circuit and a signal output end of the waveform display circuit are connected with a signal input end of the microprocessor. According to the technical scheme, the high-accuracy handhold digital oscilloscope overcomes the shortcoming that a traditional oscilloscope cannot store and analyze detecting results, and the measuring accuracy of a whole system is improved.

Description

technical field [0001] The invention relates to a digital oscilloscope, in particular to a high-precision hand-held digital oscilloscope. Background technique [0002] The oscilloscope is a comprehensive electrical signal testing instrument, which can convert the invisible electrical signal into a waveform that can be directly observed and displayed on the display screen. The relative size and change of the voltage, the magnitude of the alternating electromotive force generated from the electromotive induction. The current digital oscilloscope is complex in structure, high in cost, and low in intelligence, and cannot store and analyze the measured data. Contents of the invention [0003] The object of the present invention is to provide a high-precision hand-held digital oscilloscope with simple structure, low cost and high degree of intelligence in order to solve the above problems. [0004] The present invention is achieved through the following technical solutions: ...
