Hi, Marcus Thank you for your reply. I tried a UHD 3.15(x64 VS2009). There is no "Error: LookupError: IndexError: multi_usrp: RX channel 12 out of range for configured RX frontends". But when press "Ctrl + C" to stop rx_samples_to_file.exe then fifo timed out error occured.
Setting RX Freq: 1.000000 MHz... Setting RX LO Offset: 0.000000 MHz... Actual RX Freq: 1.000000 MHz... Press Ctrl + C to stop streaming... Done!
