Hi, all, I test OpenBTS 1.2 ,but fault, please help me!
my dev hardwave.
USRP Rev4
two RFX900
software
Ubuntu 8.04
Gnuradio 3.1.2
OpenBTS 1.2
I don't know, why actual freq = -3200000.0?
const float USRPDevice::LO_OFFSET = 4.0e6;
why do it?
bool USRPDevice::setTxFreq(double wFreq)
{
// Tune to wFreq+LO_OFFSET, to prevent LO bleedthrough from interfering with transmitted signal.
double actFreq;
if (!tx_setFreq(wFreq+LO_OFFSET,&actFreq)) return false;
bool retVal = m_uTx->set_tx_freq(0,(wFreq-actFreq));
COUT("set TX: " << wFreq-actFreq << " actual TX: " << m_uTx->tx_freq(0));
return retVal;
};
bool USRPDevice::setRxFreq(double wFreq)
{
// Tune to wFreq-2*LO_OFFSET, to
// 1) prevent LO bleedthrough (as with the setTxFreq method above)
// 2) The extra LO_OFFSET pushes potential transmitter energy (GSM BS->MS transmissions
// are 45Mhz above MS->BS transmissions) into a notch of the baseband lowpass filter
// in front of the ADC. This possibly gives us an extra 10-20dB Tx/Rx isolation.
double actFreq;
if (!rx_setFreq(wFreq-2*LO_OFFSET,&actFreq)) return false;
bool retVal = m_uRx->set_rx_freq(0,(wFreq-actFreq));
COUT("set RX: " << wFreq-actFreq << " actual RX: " << m_uRx->rx_freq(0));
return retVal;
};
