WARNING: Proses Kalibrasi Ini harus di lakukan secara periodik, beberapa bulan sekali tampaknya.
Kalibrasi adalah prosedur yang dapat menolong kita untuk menjaga agar stabilitas frekuensi output dari ClockTamer terjaga untuk batasan tertentu. Hal ini dilakukan dengan cara mengukur frekuensi sebenernya dari internal TCXO ClockTamer dan men-set-kan di settingan ClockTamer.
Contoh, internal TCXO di spesifikasi 20 MHz pada kenyataannya mempunyai frekuensi 20'000'005 Hz. Offset 5 Hz di 20 MHz adalah 5/20e6=0.25 ppm (parts per million) dan di terjemahkan menjadi (5Hz/20MHz)*900MHz = 225Hz di 900 MHz (low GSM band).
Standard GSM menspesifikasi ketepatan frekuensi 50ppb = 0.05ppm di clock referensi macro-BTS dan 100ppb = 0.1ppm untuk femtocells. Menurut pengalaman kami, offset sampai dengan 500 Hz di 900MHz adalah OK untuk 90% dari telepon untuk dapat bekerja tanpa masalah. Kami menyarankan untuk mengkalibrasi ClockTamer sampai 100ppb untuk menjamin semua berjalan dengan lancar.
Catatan, ClockTamer perlu di kalibrasi ulang karena perubahan temperatur setiap beberapa bulan. Kami juga menyarankan untuk mengkalibrasinya sebelum digunakan.
Download
wget http://thre.at/kalibrate/kal-v0.4.1.tar.bz2 cp kal-v0.4.1.tar.bz2 /usr/local/src/
atau
cd /usr/local/src git clone https://github.com/ttsou/kalibrate-uhd kalibrate-uhd
Compile
Compile
cp kal-v0.4.1.tar.bz2 /usr/local/src/ cd /usr/local/src tar jxvf kal-v0.4.1.tar.bz2 cd /usr/local/src/kal-v0.4.1 ./bootstrap && CXXFLAGS='-W -Wall -O3' ./configure && make make install
Hasilnya akan ada di
/usr/local/bin/kal
Kadang kala dibutuhkan soft link ke
ln -s /usr/local/lib64/libusrp-3.4.2.so.0 /usr/lib/
Scan Frekuensi BTS GSM yang ada
Scan menggunakan

Kalibrasi Menggunakan Kal
Gunakan Kalibrate atau Kalibrate-UHD untuk mengukur offset frekuensi. Lakukan kal pada frekuensi BTS yang terdeteksi mempunyai power paling besar yang ada di dekat kita.
/usr/local/bin/kal -f 944800000
Misalnya hasilnya adalah
Using GSM-900 channel 49 (944.8MHz) average [min, max] (range, stddev) + 258Hz [239, 283] (43, 14.534289) overruns: 0 not found: 0
Cek Frekuensi Output ClockTamer
Nilai frekuensi oscilator (MHz) dari oscilator yang ada di ClockTamer tertera di nilai FOSC di output HWI. Kita bisa mencek menggunakan GUI:
Gunakan USB & Perintah
HWI
Keluar
LMX=2080 LMK=1010 OSC=20
Artinya frekuensi referensi ClockTamer adalah 20MHz.
Perhitungan Kalibrasi
Beberapa yang perlu di perhatikan untuk perhitungan kalibrasi
- Frekuensi referensi ClockTamer adalah 20MHz
- Offest hasil scanning bernilai +
- Perhitungan kalibrasi harus di balik, jadi nilainya - untuk kompensasi
maka kita dapat memasukan offset kalibrasi sekitar
-258Hz/944.8MHz*20MHz= -5.46 Hz
19999993 Hz tampaknya approksimasi yang baik ke frekuensi oscillator yang sebenernya.
Set Menggunakan GUI
Set menggunakan GUI pada kolom Fosc input:
Setelah di set, masukan di burn ke EEPROM menggunakan tombol "Set" di GUI:
Lakukan Menggunakan CLI
Cara ini lumayan ampuh. Pertama-tama, install screen
sudo apt-get install screen
sebelum melakukan proses
- Matikan USRP1
- Buka USRP1
- Sambungkan kabel USB dari PC ke ClockTamer
- Pastikan lampu kuning di ClockTamer nyala.
Hubungkan PC / laptop ke ClockTamer menggunakan
screen /dev/ttyACM0 115200,cs8,-ixon,-ixoff
kemudian menggunakan perintah `SET,,OSC` :
SET,,OSC,19999974
ClockTamer harus meresponds
OK
Jangan lupa untuk menyimpan nilai kalibrasi ke EEPROM jika kita sudah selesai. Secara manual menggunakan perintah
STE
ClockTamer harus meresponds
OK
Nyalakan USRP1 Cek offset frekuensi menggunakan Kalibrate lagi, misalnya menggunakan perintah
/usr/local/bin/kal -s GSM900
Hasil offset rata-rata tidak boleh lebih dari 20-30Hz sekarang.
Cara Kalibrasi CLI yang lebih brutal
Siapkan peralatan
- Sambungkan USB PC ke USB ClockTamer
- Nyalakan USRP1
Cek offset menggunakan perintah
/usr/local/bin/kal -s GSM900
Di Screen yang lain masuk ke ClockTamer
screen /dev/ttyACM0 115200,cs8,-ixon,-ixoff
kemudian menggunakan perintah `SET,,OSC` :
SET,,OSC,19999974
Lakukan iterasi.
- Cek offset lagi menggunakan kal.
- Kalau masih tinggi, ubah angka SET-nya
- Lakukan terus sampai offset paling minimal
Hasil berikut lumayan lah
kal: Scanning for GSM-900 base stations. GSM-900: chan: 8 (936.6MHz + 37.926kHz) power: 21071.64 chan: 35 (942.0MHz - 24Hz) power: 30642.78 chan: 36 (942.2MHz + 5Hz) power: 8403.37 chan: 37 (942.4MHz + 22Hz) power: 10209.32 chan: 42 (943.4MHz + 20Hz) power: 187264.59 chan: 47 (944.4MHz - 26Hz) power: 19250.04 chan: 49 (944.8MHz - 7Hz) power: 182554.52 chan: 50 (945.0MHz + 25Hz) power: 45762.98 chan: 58 (946.6MHz + 30Hz) power: 13648.42 chan: 87 (952.4MHz - 9Hz) power: 3964.39 chan: 113 (957.6MHz - 38Hz) power: 26276.06 chan: 124 (959.8MHz + 20Hz) power: 9930.02
Setelah offset minimal tercapai, beri perintah
STE
