Hi,
We are using the RFX-400 board (without housing) with an appropriate
aerial connected to TX/RX. Using various examples (usrp_fft.py,
usrp_wfm_rcv.py and usrp_nbfm_rcv.py) we attempted to receive a signal
over-air, generated by a handhold portable radio unit. Unfortunately We
were unable to receive our signal. We then connected a signal generator
directly to TX/RX and experimentally determined that the RFX-400 has an
RF sensitivity of approximatively -105 dBm. Is this consistent with
other peoples findings? Is it possible that the high speed digital
signaling on the USRP motherboard is significantly reducing the
sensitivity of the daughter-board?
Thanks,
Jonas
