Embodiment Construction

[0021] Embodiments of the signal monitoring method of the present invention will be described below in conjunction with the accompanying drawings.

[0022] figure 1 It is a flowchart of a signal monitoring method in one embodiment. like figure 1 As shown, the signal monitoring method may include the following steps:

[0023] S1, measure the operating voltage of each measurement point of the electronic equipment through multiple channels of the oscilloscope, and generate waveform diagrams of each operating voltage in the oscilloscope;

[0024] In this step, a multi-channel oscilloscope can be used to measure the operating voltage of each measurement point of the electronic equipment. Waveform plots can be generated in the oscilloscope for each channel's operating voltage. The waveform diagram can be displayed on the display interface of the oscilloscope.

[0025] S2. Sampling the operating voltages respectively to obtain sampling voltages and comparing the sampling voltage...

Abstract

The present invention relates to a signal monitoring method and system, wherein the method includes the following steps: respectively measuring the working voltage of each measuring point of the electronic equipment through multiple channels of the oscilloscope, and generating waveform diagrams of each working voltage in the oscilloscope; The working voltage is sampled, the sampling voltage is obtained, and the sampling voltage of each channel is compared with a preset threshold; if there is at least one channel whose sampling voltage exceeds the corresponding working threshold, control the oscilloscope to stop sampling the working voltage, intercept The current waveform diagram monitors the operating status of each measurement point of the electronic equipment according to the waveform diagram. The signal monitoring method and system have high monitoring efficiency, low human resource investment and convenient operation.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a signal monitoring method and system. Background technique [0002] Due to the rapid development of electronic technology, the updating speed of electronic products is getting faster and faster, and the quality of electronic products is getting more and more attention. Wherein, performing SI (Signal Integrity, signal integrity) test on a product with an oscilloscope is an important method for ensuring product quality. Through the oscilloscope, the electrical signal of the product can be converted into a perfect image through the oscilloscope. [0003] The method of monitoring the system signal with an oscilloscope is: select a signal, touch the oscilloscope probe to the signal pin, and then set the trigger on the signal waveform so that the oscilloscope can capture the waveform when the system signal is abnormal. [0004] The above method can only monitor a single si...
