Time Code Generator
1 Equipment Image
1) Supports two input signals with seamless manual or automatic switching
2) Provides multiple pulse and IRIG-B (DC) code outputs
3) Supports synchronization with an external 1PPS signal
4) Supports phase adjustment of output pulse and IRIG-B (DC) code signals
5) Supports manual or automatic leap-year settings, depending on the model
6) Allows clock display settings and fast adjustment by adding or subtracting one second
7) Indicates operating status and controls the equipment through the front panel
8) Reports operating status and alarms every second through the communication interface and receives control commands, enabling real-time reporting and monitoring of equipment status and measurement data
1) Optional year-month-day-hour-minute-second clock display and Julian day display
2) Optional leap-second function
3) Optional dual-card configuration in one chassis
