Hello,I would like to compile a custom firmware to disable the decimator in the USRP. I have two questions: 1) Is it as simple as commenting the "`define RX_CIC_ON" line in "common_config_4rx_0tx.vh" and then compiling the firmware? 2) USB Bandwidth is limited; by disabling the decimation, where are the extra samples going?
Similarly, is disabling the NCO and I/Q mixing as simple as commenting the line "`define RX_NCO_ON"?
