Using rfx900 with usrp rev 3 (2005)


#1

Hi,
Is it possible to use rfx900 with usrp rev 3 hardware that was released
in 2005? If yes, what changigs should be made on either board (usrp
board or rfx900 board) ?

When doing this modification, is there any performance differences
between
using a setup with this modification versus a newer USRP1 that doesn’t
need
this modification? I think I had heard that the newer USRP1 has better
clock performance or something for the RFX900 boards and didn’t know how
much a setup with this modification would perform in comparison to a
setup
with a newer USRP1 (using the RFX900 boards).

The newer way will have better phase noise.

On the RFX board
Move R36 to R34
Move R115 to R116

Put the rfx board on the USRP and run

burn-db-eeprom -t rfx900_mimo_a -f -A -B
