The XHTF330C time-based host adopts an improved redundant architecture design, and the device is redundant at the whole node, and the failure of each module does not affect each other.
The XHTF330C time-based host adopts an improved redundant architecture design, and the device is redundant at the whole node, and the failure of each module does not affect each other; The host has a complete self-checking mechanism, the fault can be located to the interface, the module supports plugging and unplugging, and can be quickly repaired; the host has a flexible output interface configuration, which can be configured with different output modules to achieve signal path expansion; The host can add an expansion chassis to implement module slot expansion.
It can be applied to navigation communication, space monitoring and control, astronomical observation and weapon launch and control.
Features
● The GNSS (Beidou and GPS) satellite timing method can be used to provide the required time signal for the mobile measurement equipment, and complete synchronization with the central station (base) time equipment;
● Able to receive 2M time code signals of the base station at the base time;
● It can generate and release time signals such as IRIG-B (DC), IRIG-B (AC), PTP, NTP, frequency pulse signals, etc.
● Provide high precision dual redundant frequency standard output signals;
● Capable of receiving and demodulating Beidou, GPS and 2M timing signals;
● With clock-setting, seconds-plus, seconds-minus, manual synchronization and leap second settings;
● Ability to establish time lead/lag;
● The time difference between the external synchronization signal and the generator 1PPS signal can be measured and displayed;
● Monitoring information such as the working status of the system device can be released in real time;
● With extended capacity for output B (AC), B (DC) timing signals;
● The human-computer interaction interface and the corresponding monitoring interface can set the receiver working mode (Beidou mode/GPS mode/mixed mode).
