Dear all,

What is the TVRX front end sensitivity?

Thanks and best regards,

It has a noise figure of roughly 10 dB.

Thanks.

And what is the minimal level of signal that can be detected by the USRP
(with the TVRX) ?

Thanks for your answer

Like for any other radio, it depends on the bandwidth of the signal.
That is why sensitivity is properly expressed as a noise figure – it is
the only universal measure of weak signal performance. The TVRX has a
noise figure of about 10 dB. The theoretical best noise figure possible
is 0 dB.
