Some hardware parameters of the USRP board

Hello, all!

I have a question about some hardware parameters of the USRP board. What
is the antenna temperature and what is the amplifier gain after the
antenna when the board we are using is RFX2400 and the antenna is the
VERT2450 ? Thanks a lot!

Hello, all!

I have a question about some hardware parameters of the USRP board. What
is the antenna temperature and what is the amplifier gain after the
antenna when the board we are using is RFX2400 and the antenna is the
VERT2450 ? Thanks a lot!

Hello, everyone!

Assuming acceptable BER and modulation scheme are known, and the free
space model is used, we want to calculate the transmission range between
transmitter and receiver. Does anyone know the hardware parameters
mentioned above, e.g. antenna temperature of VERT 2450 and amlifier
gain? Thanks a lot!

The noise figure is somewhere in the 7-10dB range.
