==Ubah Master Clock ke 52MHz==
 +
 +
Untuk keperluan [[OpenBTS]] kita perlu mengubah master clock ke 52MHz.
 +
Hal ini dapat dilakukan menggunakan perintah
 +
 +
uhd_usrp_probe --args="master_clock_rate=52e6"
 +
 +
'''Ini tidak permanen rupanya'''

LED di Muka

LED di muka akan berguna untuk melakukan debugging hardware dan software. 

LED A: transmitting
LED B: fpga loaded
LED C: receiving
LED D: fpga loaded
LED E: reference lock
LED F: board power

Ubah Master Clock ke 52MHz

Untuk keperluan OpenBTS kita perlu mengubah master clock ke 52MHz. Hal ini dapat dilakukan menggunakan perintah 

uhd_usrp_probe --args="master_clock_rate=52e6"

Ini tidak permanen rupanya

Cek Menggunakan uhd_find_devices

ketik 

uhd_find_devices

Hasilnya 

linux; GNU C++ version 4.5.3 20110311 (prerelease); Boost_104500; UHD_003.004.000-7dc76db

Device Address:
    type: e100
    node: /dev/usrp_e0

Cek Menggunakan usrp-e-loopback

cd /usr/local/share/uhd/usrp_e_utils
./usrp-e-loopback --duration 10

Cek Menggunakan usrp-e-wb-test

cd /usr/local/share/uhd/usrp_e_utils
./usrp-e-wb-test

Cek Menggunakan uhd_usrp_probe

Tulis 

uhd_usrp_probe
uhd_usrp_probe --args="model=E110"

Hasilnya 

linux; GNU C++ version 4.5.3 20110311 (prerelease); Boost_104500; UHD_003.004.000-7dc76db

Cek usrp_siggen.py

Kita dapat mencek kemampunan transmit Daughter Board menggunakan perintah 

uhd_siggen.py -f  900000000
uhd_siggen.py -f 1700000000
uhd_siggen.py -f 1800000000

Jika di monitor menggunakan usrp_fft.py di USRP1 di sisi lain akan tampak
