Re: [Discuss-gnuradio] getting IQ data from 2 uspr1 synchronously

2010-01-25 Thread Doug Geiger
Check out the usrp_multi code - I believe it all got updated to work with the hier_block2 API update. It's in gnuradio-examples/python/multi_usrp, and it comes with a custom FPGA image (pre-inband signaling - the timestamps get interleaved with the data, and the data gets de-interleaved and ord

I'm not aware of an existing way to do this on the USRP1. A function similar to the USRP2 pps input (and start_streaming_at or at least inband timestamps) would be required. In addition to a shared clock of course. Perhaps this would make a good addition for a future inband FPGA revision. Is an
