Abstract

The invention discloses a digital oscilloscope with a high waveform refresh rate. The digital oscilloscope with a high waveform refresh rate comprises a digital processing module; the digital processing module comprises an acquisition processor, a waveform processor, and a main controller; the acquisition processor is used for calculating a digital sampling signal outputted by an analog-to-digital converter into trajectory strength information and sending the trajectory strength information in a parallel manner to the waveform processor; the waveform processor is used for calculating a plurality of digital sampling signals with trajectory strength information into display waveform data with accumulated strength information and sending the display waveform data to the main controller; and the main controller is used for receiving a user input condition sent by a user input module via a CPU processor to control the acquisition processor and the waveform processor and processing the display waveform data into waveform display signals for being displayed by a display module. According to the digital oscilloscope with a high waveform refresh rate, the problem that the waveform refresh rate of the existing oscilloscope can not be further improved can be solved, and the waveform refresh rate of the oscilloscope is greatly improved.

Description

technical field [0001] The invention relates to the technical field of measurement and testing, in particular to a digital oscilloscope, in particular to a digital oscilloscope with a high waveform refresh rate. Background technique [0002] In a digital oscilloscope, the oscilloscope captures the waveform at a specific number of times per second and displays it on the display unit. This is the waveform capture rate of the oscilloscope, also known as the waveform refresh rate, and the unit is the number of waveforms per second (wfms / s). The waveform refresh rate is an important index of the oscilloscope, which can indicate the speed of the oscilloscope to acquire, process and display the waveform at one time. An oscilloscope with a high waveform refresh rate can provide more important signal features, such as the fluorescent effect that reflects the signal probability; it can also increase the probability of the oscilloscope quickly capturing instantaneous abnormal waveforms...
