Hi Rob. You are specifying use of the RX external LO correctly via device arguments. Each of the daughtercards on the N310 contains a single Analog Device AD9371 2 TX x 2 Rx RF integrated transceiver. The two Tx channels share an LO and the 2 Rx channels share an LO. Consequently, the TX or R

Hi, Are there any examples for using the N310 with external LO? I have gotten some strange results (strange spectral mirror-ing) when using as just a 4 channel receiver. I am using the "args" argument to set rx_lo_source, but my code is setting the individual channel frequencies as I do for other
