LFRX A:A and A:B as independent channels in GRC

GNU Radio

Using just Gnu Radio Companion, is there a way to get the A and B inputs
of an Ettus LFRX (or BasicRX) in an N210 as independent channels?

Specifying A:AB as the subdevice and using a Complex-to-Float might
work, but I’m wondering if the complex rx chain in the FPGA would
conflate what are otherwise independent signals.

Try this:

Setup the source block for 2 channels.

Set the subdev/frontend spec to “A:A A:B”

This makes DSP0 get the data from dboardA (the only one there), and
frontend A, and DSP1 gets from frontendB.

Exactly what I had in mind. Thanks!
