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

I currently have an x310 with a ubx-40 in each of slots A and B. I have one 10Gig Ethernet connection hooked up, and would like to receive on both channels A and B. I tried using the “rx_multi_samples” function, but I didn’t get a good feeling I was collecting on both channels. I tried using
