For USRP1 and N2XX, you get it by default, and UHD figures out what to do (for the most part) based on your configuration.Hope i am not asking a silly question.. Where can i find the "Dual -DDC"feature.Is it confined to a particular version.Since i don't find it .Thanks!
For B100, you need the _2rx FPGA image. See the attached dual_channel_wbx.grc example attached.Note that the subdev spec shows the same subdev for both channels: A:0 A:0 in this case
And you have to use some of the magic in uhd.tune_request() to enable manual setting of the RF frequency, which we simply calculate as the midpoint between the two desired frequencies, and then we let the DDCs sort things out from there.
