Hi I'm using an RFX400 with my revision 3 USRP.
After digging through the archive I found that I needed to modify the RFX400 and then update its EEPROM as described here: On Thu, Feb 8, 2007 at 10:18 AM, Matt Ettus <[email protected]> wrote: > > All RFX boards currently shipping are configured for MIMO_B mode, which > requires a Rev 4 or higher USRP (serial number greater than 500). > > If you wish to use it with a USRP with a serial number below 500 you > will need to do the following: > > Remove R115 (zero ohms) and place it at R116 > Remove R36 (zero ohms) and place it at R34 > Put the RFX on a USRP (side A) and run the following: > > usrp/host/apps/burn-db-eeprom -f -A -t rfxYYYY_mimo_a > > where YYYY is the board you have (i.e. 400, 900, 1200, 1800, > or 2400). > The hardware mods are made but I get an error when I try and set the daughterboard type using "burn-db-eeprom -f -A -t rfx400_mimo_a" and it says this: Traceback (most recent call last): File "usrp/host/apps/burn-db-eeprom", line 69, in <module> 'xcvr2450' : ((XCVR2450_TX, 0x0000), (XCVR2450_RX, 0x0000)), NameError: name 'XCVR2450_TX' is not defined usrp_print_db.py gives me the following so I am sure side A is the right side A ;-) RX d'board A: Flex 400 Rx MIMO B RX d'board B: TV Rx TX d'board A: Flex 400 Tx MIMO B TX d'board B: <none> Any clues?
