synchronize PCI 6221 to a 10 MHz exeternal clock

[Resobis]

Hello,
I am looking to synchronize a signal generator and a PCI 6221 DAQ card. The signal generator can generate a 10 MHz clock or accept an external reference Unfortunately the lock-in range of the PLL on my signal generator is too shallow and cannot synchronise with the 10 MHz clock generated from the DAQ card. So, I want to try the opposite (use the signal generator clock as a master to sync the DAQ card).
Is it possible to use a 10 MHz signal to synchronize a DAQ card? I am thinking to use the RefClk.Src node property to sync the two device and send the clock from my signal generator to one of the PFI input but I don’t find information on the shape of the signal I should set to the PFI input (the signal generator output a 10 MHz square wave between +/- 0.5 V).
Is there a proper solution to synchronize the two devices?

Thanks,

Hi
I think this links  can help you and there are examples how to do that.
