Ah this is exactly what I have been grappling with as well. Basically
you need to set the MUX _such that_ you can access the two setting
simultaneously. If you have the gnuradio source you, look at the file
gnuradio-examples/multi-antenna/multi_scope.py
For more than one signal, you can no longer
load a special FPGA image file, the details of which are
shown in the example. However for getting only 2 signals the standard
FGPA config is good enough (there is an earlier post on this somewhere
in the archive). Maybe others can correct me if I am wrong.
