The starting principle of a high-frequency oscillator is that the oscillating circuit consists of a resonant circuit that generates a high-frequency oscillating signal. The oscillating signal is amplified by an amplifier and output to an external circuit. The external circuit receives the high-frequency signal and performs signal processing or controls the operation of other devices.
High-frequency oscillator performance indicators generally include output frequency, output power, frequency stability, phase noise and so on. Output frequency refers to the frequency of the electromagnetic wave output by the high frequency oscillator, usually in Hertz (Hz) as the unit.

High-frequency oscillators are widely used in communications, medical, industrial and other fields. In the field of communications, high-frequency oscillators are the core components of transceivers, radar, satellite communications, radio broadcasting and other equipment. In the medical field, high frequency oscillators are mainly used in medical equipment such as scalpels, electrotherapy machines and other equipment. In the industrial field, high-frequency oscillators are widely used in electronic equipment testing, high-frequency heating, sterilization, powder coating and other fields.
High-frequency oscillator maintenance skills
1, oscillator monthly timing to clean up dust and heat dissipation fan, so as not to cause the electronic tube due to insufficient heat dissipation caused by the burnout and dust caused by high-frequency jump fire.
2, the monthly timing of the chassis components of the air gun to clean up clean.
3, the use of power supply voltage to meet the power requirements of the machine, otherwise the machine appears to be poor stability.
4, the mechanical part of each shaft joint, bearings, T-head (T-machine) inside and outside the tube to do weekly dust, refueling. Check the mechanical thermal movement caused by mechanical screws loose in time to give solid.
5, the machine should be unplugged when not in use, put in a dry place to avoid high pressure part of the moisture.
6, pneumatic components should be regularly drained and refueling (oil).
