Modifikasi RFX Board
Older RFX boards require modifications to use the motherboard oscillator.
If this is the case, UHD will print a warning about the modification.
Please follow the modification procedures below:
Step 1: Disable the daughterboard clocks. Move R64 to R84, Move R142 to R153 Step 2: Connect the motherboard blocks. Move R35 to R36, Move R117 to R115
These are all 0-ohm, so if you lose one, just short across the appropriate pads
Step 3: Burn the appropriate daughterboard id into the EEPROM
cd /usr/local/share/uhd/utils ./usrp_burn_db_eeprom --id=<rx_id> --unit=RX --args=<args> --slot=<slot> ./usrp_burn_db_eeprom --id=<tx_id> --unit=TX --args=<args> --slot=<slot>
- <rx_id> pilih sesuai dengan RX ID untuk daughterboard
RFX400: 0x0024 RFX900: 0x0025 RFX1800: 0x0034 RFX1200: 0x0026 RFX2400: 0x0027
- <tx_id> pilih sesuai dengan TX ID untuk daughterboard
RFX400: 0x0028 RFX900: 0x0029 RFX1800: 0x0035 RFX1200: 0x002a RFX2400: 0x002b
Untuk 900MHz
./usrp_burn_db_eeprom --id=0x0025 --unit=RX ./usrp_burn_db_eeprom --id=0x0029 --unit=TX
- <args> are device address arguments (optional if only one USRP is on your machine)
- <slot> is the name of the daughterboard slot (optional if the USRP has only one slot)
