What does uhd_usrp_probe show in the "RFNOC Blocks" section on this device?Yes I am setting fft for magnitudes. On the front side, I am doing a log. I perfectly understand where infinity comes from. I don’t understand why the FFT returns 0. But how can I configure the Window?

Do you have your FFT configured for log output? Because the logarithm of zero is undefined.
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] 2 Unresolved connection(s) [ERR] (window0-out_0 -> fft0-in0) [ERR] (fft0-out_0 -> ep1-in_0) [INF] (('radio0', 'ctrl_port', 'master'),) [INF] (('radio0', 'time_keeper', 'listener'),) [INF] (('radio0', 'x300_radio', 'slave'),) [INF] (('_device_', 'ctrlport_radio', 'slave'),) [INF] (('_device_', 'time_keeper', 'broadcaster'),) [INF] (('_device_', 'x300_radio', 'master'),) Please tell me what could be the problem and how can I add the Window block to my image?
