-the mechanism of oscilloscope
Oscilloscope would express the waveform with mixing three factors of time, voltage and luminance. And the three factors may be worked when oscilloscope is expressing sinusoidal wave. In oscilloscope, it is very important to accurate the timing coincided with the three factors of time, voltage and luminance. If the three factor were not coincided each other, the waveform may be flowed without stopping or overlapped with another waveforms. So it is very important when the sweep is moved. If we dont repeat the signal what we want to know with no coinciding, we dont get the signal by stooping the waveform. Synchronization is said that the section repeating the sweep is coincided with period of the signal. And moving the synchronized sweep is said triggering

-the mechanism of cathode cay display
The major composed factor of oscilloscope is CRT. CRT is vacuum tube that electron is accelerated by effect of electric field and is biased. Electron is biased in the various direction by the two deflecting plates. In short the electrons is sparkled by crashing a fluorescent material covered with surface of CRT. Then the special circuit may adjust a horizontal position and vertical position.
