在官方给的demo里可以发送正弦波,但是波的频率和带宽应该怎么设置呢,
2400000000UL, //rx_synthesizer_frequency_hz *** adi,rx-synthesizer-frequency-hz
2400000000UL, //tx_synthesizer_frequency_hz *** adi,tx-synthesizer-frequency-hz
和
case DATA_SEL_DDS:
dds_default_setup(phy, DDS_CHAN_TX1_I_F1, 0, 10000000, 250000);
dds_default_setup(phy, DDS_CHAN_TX1_I_F2, 0, 10000000, 250000);
dds_default_setup(phy, DDS_CHAN_TX1_Q_F1, 0, 10000000, 250000);
dds_default_setup(phy, DDS_CHAN_TX1_Q_F2, 0, 10000000, 250000);
两种对频率的设置方式应该怎么理解
