Hello, We are using a E310 device to capture a signal and further process it in Matlab. We also have a frontend that lift the received signal around 43 dB before going into the E310.
When we use direct RF to baseband conversion we observe a high DC suppression, around 50 dB (see figure here <https://imgur.com/a/sLWyE>) Is there any way to avoid it or the only option is to move this "hole" by tuning the lo_offset in tune_request_t (then not using direct RF conversion, but converting to IF first) further away from the signal I'm interested in? And out of curiosity, which would be the exact block of the rx chain which is performing this DC suppression? Regards, Brais.
