Abstract

A digital oscilloscope with a high waveform refresh rate includes a digital processing module, the digital processing module includes an acquisition processor, a waveform processor, and a main controller, and the acquisition processor is used to calculate a digital sampling signal output by an analog-to-digital converter Generate a track intensity information and then send it to the waveform processor in parallel; the waveform processor is used to calculate a plurality of digital sampling signals with track intensity information into display waveform data with accumulated intensity information and display the The waveform data is sent to the main controller; the main controller is used to receive the user input conditions sent by the user input module through the CPU processor to control the acquisition processor and the waveform processor and process the displayed waveform data It is a waveform display signal for the display module to display. The oscilloscope of the invention solves the problem that the waveform refresh rate of the existing oscilloscope cannot be further improved, and greatly improves the waveform refresh rate of the oscilloscope.

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...
