Hey Folks, I'm struggling with the external LO feature of my N310. This issue might be related to http://lists.ettus.com/pipermail/usrp-users_lists.ettus.com/2018-April/056233.html .
Setup: Signal generator outputs a continuous wave at 2.002 GHz (-50dBm) to the RX2 of RF0. With internal LO everything is fine (see pic1). Problem: In the next step I use the device argument "rx_lo_source=external" and provide a 4 GHz CW with 3 dBm at LO IN 0/1 RX. The spectrum now shows a significant image of the input signal. I played around with level of external LO without any changes. Any ideas? Thanks in advance! :) Kai
