Multimode multi-machine X-channel programmable pulse synchronization control method and device

The present invention discloses a multi-mode multi-channel programmable pulse unit X synchronous control method and apparatus, the method: to a fixed reference time, the current time are provided time differencing a vinylidene group time, and then obtains partial time difference between the two groups, the second conversion unit, and then use the cycle length of the channel to obtain the current time state where the pulse period. The present invention enables multiple does not turn on while the output of the programmable pulse waveform synchronized improve the time and frequency synchronization accuracy at the same time does not turn on multiple, time synchronization accuracy can be provided tens of nanoseconds.
