    Tips: How does a handheld oscilloscope work?

    Simply put, an oscilloscope is an electronic device that is widely used in the field of measurement. This oscilloscope can be used to measure electrical wave signals that cannot be seen by the human eye, and then transform these vapors into visible images that are presented on the instrumentation so that people can take the next step in their research with the help of images. Oscilloscope in the work, the use of something called an electron beam hit the screen, the screen because there is fluorescent material, so it will produce a lot of fine points, which people can see with their eyes. People use the oscilloscope can detect various signals in time back a change in characteristics, through the drawing of a good waveform line to study.

    Any jump edge in the signal captured by the portable oscilloscope will act as a trigger event and start a new waveform acquisition process, which is especially useful when acquiring an eye diagram from a digital data stream, or when used with a signal that occurs only once.
