I think I sort of figured it out, though the motherboard, subdevice and channel terminology is still confusing.
1) Each USRP X300 has 1 motherboard 2) Each motherboard has two subdevice slots, A and B 3) Each subdevice slot has 1 channel If I want to use both subdevices on USRP1 and only one subdevice on USRP2 then the following settings would make that work: Device Arguments := "addr0=192.168.10.2,addr1=192.168.11.2" Mb0: Subdev Spec := A:0 B:0 MB1: Subdev Spec := A:0 Num Channels := 3 To use only 1 subdevice on each USRP this would work: Device Arguments := "addr0=192.168.10.2,addr1=192.168.11.2" Mb0: Subdev Spec := A:0 MB1: Subdev Spec := A:0 Num Channels := 2 To use all 4 subdevices at the same time: Device Arguments := "addr0=192.168.10.2,addr1=192.168.11.2" Mb0: Subdev Spec := A:0 B:0 MB1: Subdev Spec := A:0 B:0 Num Channels := 4 Will there every be a situation where I would do something like A:1 instead of A:0 in the subdevice specs?
