Hello,
I have customized the rfnoc DDC. I have:
- 4 inputs (0,1,2,3).
- 4 outputs (0,1,2,3).
- 4 independently tunable DDCs.
- Input 0 connected to outputs 0,1,2,3.
- Input 1,2,3 disconnected.
I attach a diagram.
But I do not know how to connect inputs 1,2,3 to a null source for . Any
ideas?
I have tried a custom split_stream with 1 normal output and 3 outputs with
the null_source module to not consume bandwidth. But I have the error:.
* File "/home/cruiz/repositorios/gr-ettus/examples/rfnoc/rfnoc_siggen.py",
