Dear Matt, Dear Eric, Is there away to disable (or bypass) the USRP FPGA DDC half band filter? I want to get the samples directly from the CIC decimation filter and do the low pass filtering by software. I developed a MATLAB based professional 100KHz bandwidth digital down converter as shown in the attached m file. I want to test this design in USRP. In the mean time, I cannot do this because I don't have access to the CIC output samples because of the HBF. Waiting for your help, thank you.
