Introduction of C-band modulation monitor electronic circuit

This circuit is connected to the radio using a T-coaxial connector on the transmission line. Turn on the transmitter, place S1 in the CAL (calibration) position, adjust R2 to bring the indication to full scale, and return S1 to the MOD (modulation) position.
The monitor is a component of the closed-circuit monitoring system (cctv), which is the display part of the monitoring system. It is the standard output of the monitoring system. With the display of the monitor, we can view the image sent from the front end. As an indispensable terminal device for video surveillance, it acts as the "eye" of the monitoring personnel and plays a key role in the subsequent investigation.
As the display terminal of the closed-circuit monitoring system, the monitor is an indispensable part of the monitoring system in addition to the camera. For a long time, monitors have been mainly used in finance, jewelry stores, hospitals, subways, railway stations, airports, exhibition centers, commercial office buildings, leisure and entertainment venues, etc., responsible for security work. In recent years, due to the development of technology, the cost of the closed-circuit monitoring system has been well adjusted. Nowadays, more and more small enterprises are also affordable, and they have begun to establish their own monitoring systems to achieve security or other monitoring needs.
