RE: [Discuss-gnuradio] what does the "corresponds to DC in the IF"mean?

Thanks for the answer.
Is that mean if I set the center frequency at 2.5G(RFX2400),the DC is also at 2.5G?or other values?
 
                                                                                                      Thank you
