Hello Mark, rx_samples_to_file will only receive a single channel. It is a minimal example.
Try: rx_multi_samples --channels 0,1 This will receive two channels, a pair of UBXs only has one RX channel per daughterboard so UHD can infer the sub device specification. The default sample rate is 100 MS/s so both channels will fit into a single 10 GigE connection. Make sure to follow the advice of any warnings printed to improve the throughput of your network interface card. If you have an external 1PPS source you can add `--sync pps --secs 0.1` to the above parameters to synchronize the two channels. The example currently forces an external source when synchronizing. If you remove/comment out line 98 and recompile it will use the internal source.
