Modifikasi RFX Board

Buard 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

Contoh Burn EEPROM ke 1800MHz

cd /usr/local/share/uhd/utils
./usrp_burn_db_eeprom --id=0x0034 --unit=RX
./usrp_burn_db_eeprom --id=0x0035 --unit=TX

Contoh Burn EEPROM ke 900MHz

Untuk burn EEPROM RFX RX 900MHz

./usrp_burn_db_eeprom --id=0x0025 --unit=RX

Keluar

Untuk burn EEPROM RFX TX 900MHz

./usrp_burn_db_eeprom --id=0x0029 --unit=TX

Catatan Untuk RFX Board Lama

Untuk RFX board lama kita perlu melakukan:

  1. Disable the daughterboard clocks. Move R64 to R84, Move R142 to R153
  2. Connect the motherboard clocks. Move R35 to R36, Move R117 to R115

These are all 0-ohm, so if you lose one, just short across the appropriate pads
