Timing and Synchronization
The Model 71861 front panel Sync Bus Connector provides clock, sync, PPS, and gate input/output signals. The front panel also has two coaxial SSMC connectors for input of an external sample clock and an external gate/trigger.
The front panel interface allows one Model 71861 to act as a Master, driving the clock, sync, and/or gate signals to the Sync Bus. Up to three Slave 71861s can be driven by the Sync Bus, supporting synchronous sampling and sync functions across all connected boards. If more than four boards need to be synchronized, Pentek’s Model 7893 Clock Generator allows synchronization of up to eight boards. Note that the Model 7893 is a PCIe board.
