[Discuss-gnuradio] Multiple RX channels

[Marcus Leech]

How do I arrange for there to be multiple input channels from the USRP when I have two Rx daughtercards?

I have a dual-polarization feed now, with dual DBS_RX cards, and I want to compute the cross product between
  the two channels.

In my existing code, there's:

          self.u = usrp.source_c(decim_rate=options.decim)
          self.u.set_mux(usrp.determine_rx_mux_value(self.u, options.rx_subdev_spec))

Can I do something like:

          self.u1 = usrp.source_c(decim_rate=options.decim)
          self.u1.set_mux(usrp.determine_rx_mux_value(self.u1, 'a'))

          self.u2 = usrp.source_c(decim_rate=options.decim)
          self.u2.set_mux(usrp.determine_rx_mux_value(self.u2, 'b'))

Would that be what I wanted?

Cheers
