[Discuss-gnuradio] 4 RX with 2 WBXs?

2010-09-10 Thread Scott Storck
I have a USRP and two WBX daughterboards. Is it possible to use 4 independent RX antennas (all tuned to the same frequency) with this hardware setup? Specifically, here's what I'm trying to achieve: Antenna 0 - Side A WBX, RX/TX port - ADC0 - DDC0I Antenna 1 - Side A WBX, RX2 port - ADC1 - DDC1I

Jason and Marcus, thanks for your responses. I was afraid that this was the case. Is there a daughterboard out there (besides the BasicRX) that can support 4 antennas on a single USRP? The other option that would work for me is connecting antenna 0 to WBX 0 and connecting antennas 1-3 to WBX 1

If the signals you want to receive are sufficiently close to each other, you could tune the WBX in the middle and use two independent DDC to receive two signals with one WBX ... (I'm not mistaken ...) Cheers, Sylvain ___ Discuss-gnuradio mailing
