Maximum RF Input Power

Hi everyone,

I’m trying to determine the maximum safe RF power I can feed into the
DBSRX and TVRX daughterboards. I have looked at the datasheets, for the
boards’ tuners, but I am still not certain enough.

Does anyone know what the maximum safe (no risk of damage to the
daughterboard or USRP) input power is for these boards? Also, what is
the maximum usable (no distortion due to excessive power) input power
for these boards?

I am asking this becuase I am interested in trying the USRP as a VNA and
could be feeding it several dBm (perhaps 10 dBm) unless I take
precautions.

Thanks!

-20dBm is a good safe maximum.
