You are probably ok, but you might also want to use bandpass filters to keep the excess TX power out of the RX. Matt On Wed, Jan 4, 2012 at 2:59 PM, Ed Criscuolo wrote: > I'm working on an application that will do full-duplex using an RFX2200 > daughterboard in a USRP1. > > The transmit frequenc

[Discuss-gnuradio] Full Duplex with RFX2200

2012-01-04 Thread Ed Criscuolo
I'm working on an application that will do full-duplex using an RFX2200 daughterboard in a USRP1. The transmit frequency will be about 2.055 GHz, and the receive freq will be about 2.255 GHz. Up until now, we've been working with only the transmit or the receive flowgraph separately. Now we're

Hi, 1) I removed tx_io[15] from my design 2) Change fifo_not_full signal to fifo_almost_full 3) I tried to follow most of your suggestions to achieve better timing 4) I use minimum cable length. Now I'm observing strange behavior. I grounded Virtex board and USRP2 board t

2012-01-04 Thread merve deniz
Hi all, Using RFX1800 daughterboard and two computer, I sent a signal from one usrp to the other. The signal's frequency is 100KHz and usrp sink at 1.7GHz. Also usrp Source is at 1.7Ghz. Sample Rate is chosen 1M so decimation 64 and interpolation 128. Usrp sink gain is useles I guess, because I cha
