[Discuss-gnuradio] Maximal signal bandwith for the usrp

[JALLON Pierre 201932]

Dear all,

 

According the USRP v4 description:

http://www.ettus.com/downloads/usrp_v4.pdf

the usrp is able to process signals up to 16MHz.

 

As the USB port is limited to 60MB/s, and if the samples are coded on 32 bits (16 for Q and 16 for I), the maximal bandwidth equals 15MHz.

 

Which version is correct?

 

Furthermore, considering that the first ADC works at 64Ms/s, the available rate for the USB equals:

32/2 (is it available ?)

32/3

32/4

32/5

…

32/256

 

Am I right ?

 

Thank you for your answers,

 

Pierre Jallon
