Multiple chassis PXI triggering over fiber


Thread Starter

I'm in the early stages of investigating a fast, physically distributed data acquisition system and am considering using a Compact PCI or PXI solution from NI.

We require about 4-5 acquisition chassis around the facility and these need to be triggered at the same time to start acquisition and then to stop it. Fiber optics are needed to route the trigger signals.

Is anyone aware of an off-the-shelf solution for distributing clock, timing and trigger signals over fiber that integrates nicely with the Compact PCI or PXI chassis?

Thought I'd ask before designing my own!
