Re: [Discuss-gnuradio] X310 with 2 WBX in full duplex

Few mistakes I caught after sending it. Center frequencies I had chosen were out of range for WBX. Fixed now. Also, image file now has proper extension.

Thank you,

Subject: X310 with 2 WBX in full duplex

 

Hi,

I'm trying to get two Tx-Rx links running with an X310 with two WBX daughterboards in it. I've used multi-channel USRP source/sink blocks, but I'm experiencing latency (L) errors with the connection, and then the application (GRC) hangs. I've attached an image of my USRP source/sink blocks. I'm connected to the X310 with a 1GB ethernet connection.

Can anyone point out the reason/mistake? Also, is the sub-device spec correct? Followed instructions for WBX from here: https://www.ettus.com/content/files/kb/application_note_frontends_subdevices_antenna_ports.pdf

My goal:

I want to have a Tx-Rx link in freq F1 and another in freq F2 at the same time. One daughterboard TXes in F1 and RXes in F2, while other TXes in F2 and RXes in F1. Is this possible with the equipment I have?

Thank you,

AB
