Melakukan Kalibrasi

Gunakan Kalibrate atau Kalibrate-UHD untuk mengukur offset frekuensi,

[root@openBTS kal-0.2]# ./kal -f 946600000 -u
USRP side: B
FPGA clock: 52000000
Decimation: 192
Antenna: RX2
Sample rate: 270833.343750
average [min, max] (range, stddev)
501.351685 [461, 546] (85, 19.314581)
