Hi all, I'm using a single TwinRX in an X310, and want to stream from the two channels tuned to the same RF frequency. The second channel shall use the LO of the first channel.
I configured the RF frequency through the set_rx_lo_freq for LO1 and Channel 0, and set the rx_lo_source of Channel 1 to companion. Streaming I/Q samples shows me, that the RF front-end is not really tuned to that frequency. I only observe noise. I remove the second Channel from my source code (no change in result), and then tried to set the RF frequency via set_rx_freq with integer-n tuning. The latter version worked, showing me correct I/Q samples. Question to Ettus team: how do you correctly configure the receiver frequency for TwinRX: over the advanced functionalities of the TwinRX as described in the knowledge base, or via set_rx_freq + setting lo-source. Best regards, Emanuel
