Which electronic components are oscilloscopes used to measure?
Oscilloscope can not be used to measure electronic components, it is used to measure the electrical signal waveform of a node in the circuit.
Oscillograph is a kind of electronic measuring instrument with wide range of uses. It can transform the electrical signals invisible to the naked eye into visible images, so that people can study the changing process of electrical phenomena.
The oscillograph can observe the waveform curves of various signal amplitudes with time, and can also use it to test various electric quantities, such as voltage, current, frequency, phase difference, modulation amplitude and so on.
An oscilloscope uses a narrow, high velocity electron beam to hit a screen with a fluorescent material to produce tiny spots of light (which is the work of a conventional analog oscilloscope). Under the action of the measured signal, the electron beam is like a pen's pen tip. It can depict the instantaneous change curve of the measured signal on the screen surface.
