Does the X310 have any real-time DC offset calibration? I am aware of the separate calibration procedure and resulting CSV file which provides a lookup for the correction at a given frequency. But, this is a fixed correction as opposed to a dynamic one.
I am seeing a large LO leakage signal at the beginning of a capture but then the level gradually gets canceled as time progresses. This is behavior i would expect of the B210 or N310, but not the X310. So, just wanted to double-check what I should be seeing prior to spending too much time investigating. I am using an X310/UBX with custom FPGA image which adds 2 FFT blocks. I have my own c++ application linked to UHD master branch and calling functions out of the RFNoC API to produce a Rx path of Radio->DDC->FFT->host. Rob
