Hello, I have a problem that when receiving samples from the USRP E310
board, after the FFT block at low gain, zero values are received.
After that I log them and get infinity. I wanted to figure out what
the problem is, but I have no idea, maybe the Window block will fix
the situation. But when building my yaml file, I get the error: [ERR]

how can I add the Window block to my image?

Do you have your FFT configured for log output? Because the logarithm
of zero is undefined.
