[USRP-users] 回复: RFNOC: Radio doesnot work in Tx Mode for E310

I placed one “Stream to Vector" block between analog:siggen and RFNOC:FIFO. It work! The red TX led lights up. It seems that the issue exists in the data/stream format. Further, I use the RFNOC: SigGen as the source, and notice the siggen enabling sequence according to the post: http://lists.e

I'm thinking that timed tune commands will not work on tagged streams in burst mode. Is that correct? I've been looking at the USRP sink block code and it supports the timed commands on the stream, but from reading a recent thread, it seems like this will not work because of how the DUC derives

Your virtualizer needs to support Jumbo frames for any reasonable packet rate. You saying the MTU being at most 1500 means that either your network hardware can't do Jumbo frames (unlikely, in 2020), or that you're not passing through your network properly into the VM. You'll want to investigate t
