We have a USRP2 with an RFX900 daughtercard. I seem to be unable to capture signals of any kind. After doing some research I read that the highest recommended input power is 0dBm, which I'm quite certain I have exceeded on more that one occasion during my attempts to get it working. Using a high-frequency PCB probe attached to a spectrum analyzer, I used a signal generator (920MHz signal @ -15 dBm) and measured the input and output of the amplifier U4, MGA82563. I am seeing approximately -45 dBm at the input to the amplifier and -65 dBm at the output. I'm assuming this means the chip is fried.
My question is, how likely is it that this is the only part that was damaged? I'm hoping that this could be as simple as replacing the chip. _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
