[Discuss-gnuradio] question about RFX2400

Hi, I am testing a transceiver link in ISM band using two USRP2+RFX2400, one configured as TX and the other one as RX. I would like to test my own FPGA program, so for now I have your FPGA codes in which I only changed the signal driving the DAC in TX to be an square wave (+8191 or -8192) wit

[Discuss-gnuradio] USRP2+RFX2400, TX only and RX only configuration

HI, I would like to configure two USRP2+RFX2400 boards one as the TX only and the other one as RX only, so on the TX board I set: io_tx_05=1 => the enable(pin 8)of the transmitter mixer (U101) is always high, so the mixer is always active io_tx_06=0 => the TX/RX (U202) works always as TX a

Hi Nick, I have a USRP2 + RFX2400 which I'd like to use as a transceiver. here are my questions: 1- Assuming I get two antennas, one connected to TX/RX port and the second one connected to RX2 port, Can I get the first antenna to act as the TX (driven only by DAC) and the second one act as RX

I have changed the FPGA code and I have built the bit file for it. I would like to keep the same firmware but just change the FPGA code. What should I do now? Thanks, Malihe Nick Foster wrote: Malihe, Your understanding is basically correct. I misunderstood your request -- I didn't realize

Hi Nick, I think I should explain my project better. We are developing a physical layer protocol for an asynchronous packet based transceiver all in Verilog. The design has been simulated so far using ModelSim. The target of the project is the VLSI fabrication of this design. Thus all the sig

Hi Nick, Actually we are using the USRP2 not for a SDR application, but we are using it to test our physical layer asynchronous backet based communication. For that I have to change the FPGA code and remove the interpolation/decimation and replace it with a spreading scheme. for that I need t
