Yeah, I know 9361 doesn't support external LO, that's why I am looking into purchasing N320. I am interested in the ability of fast sweeping to do spectrum sensing/monitoring. I thought about building a custom super-heterodyne front-end and driving it from, say, the GPIO pins of the SDR but lookin

Hi Marcus, Thanks for your prompt response! Your answer is in line with my expectations. I was mostly wondering how set_rx_freq would interact with an external LO. Like would the tune_request only allow for DSP tuning whereas RF tuning would be (hardware) locked within UHD? With external LO, woul
