Hi Nick,
I have a USRP2 + RFX2400 which I'd like to use as a transceiver. here
are my questions:
1- Assuming I get two antennas, one connected to TX/RX port and the
second one connected to RX2 port, Can I get the first antenna to act as
the TX (driven only by DAC) and the second one act as RX (driving only
ADC)? If so, do I get 30MHz of bandwidth on each antenna?
2- Is that true that if I don't configure the DAC, it will use its
default values for example for the modulation, upsampling factor, ....?
3- I understand the default modulation of DAC is "NONE", what is the
default interpolation rate (none, 1x, 2x or 4x)?
4- Assuming I configure the DAC IF frequency to be 0 (modulation
="NONE"), does that mean if I pick the RF center frequency of the TX and RX
to be the same, I need no demodulation (to be implemented inside FPGA
)on the data captured from ADC and this data is all baseband?
5- At the TX side, does the dac_a carry interleaved I/Q? or dac_a
carries only I and dac_b carries only Q of the same samples?
6- At the RX side, does the adc_a carry interleaved I/Q? or adc_a
carries only I and adc_b carries only Q of the same samples?
Thanks,
Malihe
