Correction: Spectrum shows fine. Just had to enlarge the panel:)

Thanks Jonathan,
That helps a lot. I still don't get a spectrum, but I get a nice fosphor
panel and no timeout errors. A couple of questions:
1) You seem to be using 2 ffts: RFNoC FFT and RFNoC Fosphor. You can only
do 1 FFT. What's the difference between those 2?
2) You start with an RFNoC Radio
Upon closer inspection I do get a few runtime errors:
timeout on chan 0
Looks like smt is amiss in my flow. Any ideas about that?
TIA

Tyvm Jason,
That did it. I don't actually need to set the X300's addr and type to
anything. It defaults to the first one it finds, and I got only 1 ;-)
I got the top block running without any errors. Not much of a fosphor
display, like I'm used to, but I'm happy i didn't get any errors:)

Nikos, All RFNoC scripts require a Device3 block. If you look under
UHD>RFNoC in GRC you will see Device3. Just add that to your design (no
connections needed) and if you are using an X310, set your device
argument to "ad
Hi,
Actually I managed to find a suitable block, Stream to Vec Decim under
[Sream Operators]. Now it generates fine but I get the following runtime
error:
Traceback (most recent call last):
File "/home/nikos/Desktop/top_block.py", line 143, in
main()
File "/home/nikos/Desktop/top_block.py", line
I have looked under , , and searched for
Vector*, but couldn't find any suitable blocks:(

Hi,
And many thanks for your fast reply.
Indeed that seems to be the problem. How can I convert the scalar, or is it
stream?, output from my usrp to a vector needed by fosphor?

fosphor needs FFTs as input, and it's currently set to 1024, so you need
to pass in vectors of length 1024. You're passing in scalars.

Hi,
I've been trying to start working with RFNoC blocks in grc. In this
particular flow, I get this error, which prevents execution:
