For the Basic Rx, 0xf3f2f1f0 is the correct setting to feed 4 separate signals into the I inputs of 4 DDCs, with zeros fed to the Q inputs. To use 4 channels, you must use the std_4rx_0tx.rbf fpga image. If you use the std_4rx_0tx.rbf image, the decimation rate must be <= 128. If you need more decimation, you must do it in software.
