Hello gnu-radio friends. I would like to realize RFX2400 full duplex configuration.
I am using RFX2400 on USRP2 and tried to transmit and receive(fft.py at the same time. But I got unstable spectrum for both TX/RX. Here is the video And configuration is as below. ------------------------------------- U-+RFX2400(TX/RX)+----SpectrumAnalyzer. S | R | P | 2-+RFX2400( RX2 )+----Signal Source. ------------------------------------- I found RFX2400 schematics from below URL http://code.ettus.com/redmine/ettus/attachments/9/rfx2400.pdf And I believe this situation is because of U202 / U209 to swith state cycles A->B and B->A in very often. I would like to use both U202 / U209 to fix the swith state always to "A". Would you please let me know how to make U202(RFswitch) / U209(RFswitch) fix to A state. (say "full-duplex mode") Do I still need to hardwire fix the RF-swith to A? if there is no FPGA image / firmware available to fix them. Thank you very much in advance.
