[Discuss-gnuradio] doubt about the the DC offset

[intermilan]

Hi all:
     when I run the test program test_usrp_standard_tx/rx.cc, I found that the DC offect is set to 4M. So can anyone tell me how this value come out and where can I find the process of setting this value? and can we set other values to instead of this value?
