[USRP-users] UDP packet channel id value

2018-09-20 Thread Yun Li via USRP-users
Hi there, We are capturing UDP packets while streaming multiple channels (RX channel 1 and 3 in particular) from N310 (UHD_3.13.0.2-1-g78745bda). Looking at UDP packets, it seems that the channel id field in the VRT header is actually set to 0 and 1. I expect the value would be 1 and 3. Is there a

[USRP-users] External LO amplitude issue

2018-09-28 Thread Yun Li via USRP-users
Hi there, I am testing external LO on N310 (UHD_3.13.0.2-1-g78745bda). The setup is I have a X310 sending SINE waves to N310's channel 1,2,3 via a splitter. A signal generator sends 2x frequency 3dBm signal to N310's LO IN 0/1 and LO IN 2/3 via a splitter. According to the doc, there is supposed t
