Download ttsou Kal

Download dari mesin lain & scp ke E110 

https://github.com/ttsou/kalibrate-uhd/zipball/master
cd ~/Downloads
scp ttsou-kalibrate-uhd-8200e28.zip root@192.168.0.148:

Atau via git (kadang gagal sih ini) 

cd ~/src
git clone git://github.com/ttsou/kalibrate-uhd.git kalibrate-uhd

Compile FFTW3

Download dari 

http://www.fftw.org/download.html

Lakukan 

mv fftw-3.3.2.tar.gz ~/src
cd ~/src
tar zxvf fftw-3.3.2.tar.gz
cd ~/src/fftw-3.3.2
./configure --enable-float --enable-sse --enable-shared --disable-static
make clean
make
make all
make check
make install
ldconfig

Alternatif Lain

Install dari repo 

opkg update
opkg install libfftw3

Referensi

Compile

Jika di download via web 

opkg remove --force-depends fftwf fftwf-dev task-sdk-gnuradio-native
opkg install fftwf fftwf-dev task-sdk-gnuradio-native
cd ~
mv ttsou-kalibrate-uhd-8200e28.zip src/
cd src
unzip ttsou-kalibrate-uhd-8200e28.zip 
cd ~/src/ttsou-kalibrate-uhd-8200e28
./bootstrap && CXXFLAGS='-W -Wall -O3' ./configure && make


Jika di download via git 

opkg remove --force-depends fftwf fftwf-dev task-sdk-gnuradio-native
opkg install fftwf fftwf-dev task-sdk-gnuradio-native
cd ~/src/kalibrate-uhd
./bootstrap && CXXFLAGS='-W -Wall -O3 -fPIC' ./configure && make


Error fftw3

Saat ./configure keluar error 

checking for FFTW3... configure: error: Package requirements (fftw3 >= 3.0) were not met:

No package 'fftw3' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables FFTW3_CFLAGS
and FFTW3_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.


SOLUSI:

Mungkin dengan -fPIC dalam CFLAGS jadi 

cd ~/src/kalibrate-uhd
./bootstrap && CXXFLAGS='-W -Wall -O3 -fPIC' ./configure && make

Alternatif lain, install source fftw3 dari http://www.fftw.org/download.html

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)
overruns: 0
not found: 0
