Some Testing Commands

(the root user)

• Testing whether the system is connected

usrp_probe

• Testing usb

/usr/local/share/gnuradio/examples/usrp/usrp_benchmark_usb.py

• View board

lsusrp

• Reprogram frequent band from 900 Mhz to 1800 Mhz

/usr/local/src/gnuradio-3.4.2/usrp/firmware/src/usrp2/burn-db-eeprom -t rfx1800_mimo_b -A –f

• Emission the signal

/usr/local/share/gnuradio/examples/digital/benchmark_tx.py -f 900M -T A

• Received signal via fft
