The JD-NET standard master clock is a professional level standard time signal source developed and produced for the daily operation needs of broadcasting systems in radio stations. It has the functions of automatically obtaining Beidou satellite standard time codes, uninterrupted timing to sub clocks and network systems, and automatic on-time reporting. Through strict testing by the Fifth Institute of Electronics of the Ministry of Industry and Information Technology (China Saibao Laboratory), it has obtained a single Beidou terminal testing certificate (certificate number: ETB241597).
Features
Compliant with the Technical Specification for Single Beidou Testing of Satellite Positioning, Navigation and Timing Equipment
Built in single Beidou receiver module, automatically switches signals
Built in high stability clock circuit, automatically synchronizes with the Beidou satellite system when satellite reception conditions are met, and can automatically switch to local operation when reception conditions are poor
Equipped with time code output offset adjustment function, ranging from -3 seconds to+3 seconds, it can offset the delay caused by satellite transmission delay
Delay advance information can be added to the time code, combined with JD series sub clocks and timing software, and broadcast on time after being offset by delay devices
Differential output time code is used to connect sub clocks. One master clock can drive more than 100 slave clocks simultaneously, with a communication distance of over 1000 meters
The master clock has two standard RS232 interfaces and one RJ-45 network port, used for timing workstations and network systems
Equipped with local timing function and balanced stereo XLR interface, it can achieve six tone timing and high-quality voice broadcasting
Provide outdoor high gain long-distance satellite antenna (standard 30 meters, customizable)
19 inch 1U standard chassis, dual power supply
