First let's identify what hardware you have.
What rev is your USRP? If it is rev 4.0 or higher it is capable of
driving an RFX400, an RFX400_MIMO_A, or an RFX400_MIMO_B. If it is a
lower rev, it can only drive an RFX400 or an RFX400_MIMO_A.
Does your RFX400 have X1 and X101 populated or empty?
Which of the following resistors on the RFX400 are populated -- R34?
R35? R36?
What was the eeprom originally programmed with?
Does this RFX400 work with other USRPs?
Does this USRP work with other RFX400s?
