USRP output power

Hello,
I want to know USRP output power
If I set an amplitude of a sinusoidal signal to 32767, which is the
maximum
value that USRP can transmit.
Then, at the antenna, what voltage value the sinusoidal signal swing? 5V
to
-5V?

Most of the daughtercards have a maximum output power of about +20dBm
into a 50-ohm load.
I think that works out to about 2VP-P.

The BASIC_TX puts out a maximum of about 0dBm.
