Jika kita tidak mempunyai peralatan lab yang baik dan kita ingin mengetahui akurasi clock USRP, kita dapat menggunakan aplikasi Kalibrator (Copyright (c) 2009 Joshua Lackey, Alexander Chemeris). Tentunya kita tidak mungkin memperoleh hasil yang baik seperti hi-tech lab, tapi cukup lah untuk mengetahui error kalibrasi clock yang ada.

./kal -s 850 -F 64000000

Hasil

Scanning Channel

Menjalankan

cd /usr/local/src/kal-v0.4.1/src/
./kal -c 513 -F 64000000 -b DCS

Hasil

Using DCS-1800 channel 513 (1805.4MHz)
average		[min, max]	(range, stddev)
+ 17.109kHz		[17087, 17136]	(50, 14.080007)

Kalkulasi Kalibrasi

Misalnya kita menggunakan BTS pada channel 47 untuk kalibrasi

./kal -F 52000000 -c 47

Hasil

kal: Calculating clock frequency offset.
Using GSM-900 channel 47 (944.4MHz)
average		[min, max]	(range, stddev)
+ 501Hz		[479, 524]	(45, 13.227342)

Misalnya kita menggunakan BTS pada channel 61 untuk kalibrasi

./kal -F 52000000 -c 61

Hasil

kal: Calculating clock frequency offset.
Using GSM-900 channel 61 (947.2MHz)

Proses Kalibrasi

Ukur

Gunakan Kalibrate untuk mengukur offset frekuensi, misalnya pada channel 52

./kal -f 945400000

Misalnya hasilnya adalah

kal: Calculating clock frequency offset.
Using GSM-900 channel 52 (945.4MHz)
average		[min, max]	(range, stddev)
+ 498Hz		[429, 555]	(126, 32.384548)
overruns: 0
not found: 165

Hitung Offset

Hitung dengan asumsi

Frekuensi Clock 20MHz
Kanal 52 atau frekuensi 945.4MHz
Offset hasil pengukuran + 500Hz

Maka clock 20MHz harus di offset sebesar

-500Hz/945.4MHz*20MHz=-10.6 Hz

Tepatnya menjadi

19,999,990 Hz

Set Ulang ClockTamer

Set ulang OSC pada ClockTamer menggunakan

sudo screen /dev/ttyACM0 115200,cs8,-ixon,-ixoff

Beberapa pilihan setting

SET,,OSC,19999991
SET,,OSC,19999990
SET,,OSC,19999989
STE

Scan Ulang Frekuensi

Hasilnya harus lebih baik

cd /usr/local/src/kal-v0.4.1/src
./kal -s 900 -F 52000000 -b GSM900 -vv

Semoga hasilnya memperoleh offset yang lebih baik, seperti

-Latest version of Kalibrator today is 0.2 and is available [http://sourceforge.net/mailarchive/attachment.php?list_name=openbts-discuss&message_id=3d032e5d0911101431o5bb31844mdfe80ae4fc9789ea@mail.gmail.com&counter=1 here]. Starting from the next update of OpenBTS Kalibrator will be distributed as a part of OpenBTS standard package.
-How it works¶
-Kalibrator takes advantage of the existing real networks and their accuracy. So you need to be in range within some operator's BTS. You pass the downlink frequency of the previously scanned ARFCN as a command line parameter for Kalibrator. Using some math Kalibrator can estimate the value of frequency difference between the frequency it tunes USRP to and the frequency of a BTS working in +-200kHz range near that frequency.
-Building and running¶
-To build Kalibrator with gnuradio 3.2.2 (ver. 3.1.3 is not currently supported) run 'make' and you will get binary file 'kal' which is ready for use.
-Now you need to know which ARFCN is better to use. With any GPRS modem supporting AT commands it is possible to find an ARFCN with the strongest signal. Without such modem, you have to scan whole band by manual iteration through downlink frequencies (it can be inconvenient especially on 1800/1900 band). Search this file for specific downlinks all_gsm_channels_arfcn.txt.
-Suitable channels must have at least -70 to -80dBm strenght, else you got to much overruns and the result could be misguiding. That's just good to have more channels to scan to eliminate possible wrong error. There is an example of network scan from GPRS modem (offset values are added manually).

+ + 494Hz		[481, 504]	(23, 6.454695)
+ overruns: 0
+ not found: 0
+==Proses Kalibrasi==
+===Ukur===
+Gunakan Kalibrate untuk mengukur offset frekuensi, misalnya pada channel 52
+ ./kal -f 945400000
+Misalnya hasilnya adalah
+ kal: Calculating clock frequency offset.
+ Using GSM-900 channel 52 (945.4MHz)
+ average		[min, max]	(range, stddev)
+ + 498Hz		[429, 555]	(126, 32.384548)
+ overruns: 0
+ not found: 165
+===Hitung Offset===
+Hitung dengan asumsi
+* Frekuensi Clock  20MHz
+* Kanal 52 atau frekuensi 945.4MHz
+* Offset hasil pengukuran + 500Hz
+Maka clock 20MHz harus di offset sebesar
+ -500Hz/945.4MHz*20MHz=-10.6 Hz
+Tepatnya menjadi
+,999,990 Hz
+===Set Ulang ClockTamer===
+Set ulang OSC pada ClockTamer menggunakan
+ sudo screen /dev/ttyACM0 115200,cs8,-ixon,-ixoff
+Beberapa pilihan setting
+ SET,,OSC,19999991
+ SET,,OSC,19999990
+ SET,,OSC,19999989
+ STE
+===Scan Ulang Frekuensi===
+Hasilnya harus lebih baik
+ cd /usr/local/src/kal-v0.4.1/src
+ ./kal -s 900 -F 52000000 -b GSM900 -vv
+Semoga hasilnya memperoleh offset yang lebih baik, seperti
+ FPGA clock : 52000000
+ Decimation : 192
+ Sample rate: 270833.343750
+ kal: Scanning for GSM-900 base stations.
