Phototherapy apparatus and fluorescent lamp principle
The internal reflection of aluminum film is helpful to improve the brightness of bright spot. Aluminum film and heat dissipation and other functions. When the electron stops bombarding, the bright spot does not disappear immediately, but retains for some time.
It is an important instrument for observing the phenomena of digital circuit experiment, analyzing the problems in experiment and measuring the result of experiment. The oscilloscope consists of oscilloscope tube and power supply system, synchronization system, X axis deflection system, Y axis deflection system, delay scanning system, and standard signal source.
An oscilloscope is an electronic measuring instrument that uses an electron oscilloscope tube to convert an alternating electrical signal that the human eye cannot directly observe into an image and is displayed on a fluorescent screen for measurement.
