Use multiple RPs

Post by Dri7308 » Wed Jun 18, 2014 9:43 pm

Can you use 2 or more RPs together and sync the 2 boards. In effect have a 4 channel system

Would you like to sync. ADC clocks or only triggering of the acquisition?

If you already have an external trigger signal you could simply trigger the acquisition on both Red Pitayas simultaneously through external trigger input that is available on the extension connector. On the other hand it would be also possible to define triggering conditions (input, edge, threshold) on the first Red Pitaya and sync. it over SATA connector with second Red Pitaya. In such case the second Red Pitaya would probably have another trigger source called SATA or similar. This second feature would be the best solution I think, but unfortunately it is not yet implemented.
