the xhtf321n time code terminal can receive the beidou/gps satellite signal and the irig-b time code, and use the demodulated reference signal to accurately synchronize the time-frequency signal generated by the local frequency source, and finally output the irig-b time code, the local second pulse, and other time-frequency signals (you can replace the output board to customize different output signals), and provide ntp network timing service.

the xhtf321n time code terminal has a network management interface to facilitate monitoring and control of the working state of the device.
