Question on receiver tuning issue

Thank you so much Johnathan. Is that means the signal is converted
before ADC? I’m quite confused about how the FPGA configuration connect
with host code. The FPGA bitstream is loaded by usrp.source_c or
usrp.source_s. Where is the FPGA bitstream loaded into? How does the
usrp source class load the FPGA bitstream?Â
