[Discuss-gnuradio] digitizing a digital data stream with USRP2

2010-02-17 Thread John Carlson
I have a USRP2 and I'm interested in doing an experiment where I'd like to simply use the USRP2 as an A/D and D/A device, essentially disabling the RF tuning portions. The signal I'm trying to digitize is a stream of digital TTL pulses. I assume that the best way to interface to this is through

I'm not intimately familiar with GNU radio hardware and the experts here will hopefully correct me if needed, but I think you would face these issues: 1) The default FPGA logic doesn't offer a demodulation enable/disable, so you'd have to make some logic changes and rebuild. no changes are
