Hi Francesco,

 

you can check these information on USRP data sheet:

http://sine.ni.com/ds/app/doc/p/id/ds-355/lang/en

In particular the minimum detectable signal depends on frequency.

Re: usrp 2920 minimum detectable signal??

allora approfitto e scrivo in italiano...

 

sto cercando di progettare un sistema SDRadar utilizzando la USRP 2920 ..

spero di riuscire a superare i limiti legati all'interfaccia USB della USRP di prima generazione della ETTUS.

 

ho guardato il datasheet( http://sine.ni.com/ds/app/doc/p/id/ds-355/lang/en ) e alla voce receiver trovo :

 

Max Input Power (Pin)  0dBm

 

posso fidarami di questo parametro ?non mi sembra legato alla sensibilità del ricevitore (mi aspettavo un "Min imput power")

 

Saluti Francesco
