Description

I have updated the values in the freq_min() and freq_max() functions in 3 files:
usrp/host/lib/db_flexrf.cc
usrp/host/lib/db_basic.cc
usrp/host/lib/db_dbs_rx.cc
according to the values in Ettus Research's brochures.

Fixed in r11621 and r11622. Only the RFX boards had frequency range errors. The DBSRX limits are set intentionally wider than advertised to allow the user to push the limits beyond what we spec. The Basic and LF board frequency limits in the patch are incorrect. The LF boards can do negative frequencies since they can be used in quadrature.

Ok, thank you.

Is the reason that you didn't change the Basic{T,R}X frequencies that they are intended as IF interfaces for extrernal RF frontends?
