 \subsection rdtesting_phase_rx_twinrx TwinRX specifics for phase alignment testing
 
 Phase alignment testing with TwinRX works as described above with additional test cases and commandline options.
-TwinRX offers LO sharing inside one board and across boards. For uhd_app and derived applications involving our tools and GNU Radio we have introduced `--lo-source {internal, companion, external}` and `--lo-export {True, False}` arguments to apply LO sharing feartures on TwinRX daughterboards.

 Two testcases have to pass:
  - Phase alignment if sharing LO with companion receiver on a single daughterboard
  - Phase alignment if sharing LO with external TwinRX daughterboard
