Hi Tom,
Thank you for your kind remind, I find the problem that I stored the metadata
file as inline type and I don’t need to add ‘.hdr’ with it.
Many Thanks,

Now, that means that the signal power will vary between different subcarriers
in a situation where you'd prefer OFDM over single-carrier systems - and that
makes it necessary to estimate the signal power per subcarrier, which means you

I have tried to use USRP B210 and GNUradio to send and receive signal, and now
I want to get the network's scattering parameters. But I don't know how to get

Hi all,
I just want to use GNU Radio to generate a signal with a continuous frequency
in a certain bandwidth (5.585GHz-5.615GHz)and then store the signal in a file.
How can I generate the signal? Can I use a file sink to store the signal. And
how does the data store in the sink file?
Is there
Hi Marcus,
Yes, I just want to send a sinewave which can sweep the frequency band with
same steps, and receive it in a file.
Thank you!

Yan,
simply convert "freq" and your frequency to a PMT before passing into cons().
