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.ettus.com/pipermail/usrp-users_lists.ettus.com/2017-December/055135.html, the Tx led is on. However, there is no signal being transmitted. The flowgraph still doesnot work. Now my question is how to let the RFNOC:SigGen work with RFNOC:Radio Tx. Is there any successful experience?

I have tried all the related example flowgraph and made some modifications, including alternating the source from analog:signal source to RFNOC:SigGen, w/o FIFO, w/o DUC, etc. I also made the modification according to https://corvid.io/2017/04/22/stupid-rfnoc-tricks-loopback/. The TX light indicator still keeps dark. The example fosphor works properly, so that RFNOC: Radio is OK in the RX Mode. My configurations are as follows. E310 is up-to-date. UHD version is 3.14.1 and the OS is Ubuntu 18.04. Any suggestions will be appreciate. Jason Suen
