Hi after feeding I and Q values from GUI based app to fmcomms 3 I am able to see the spectrum for transmitter side (source side) so everything is correct and evm is also good but in between I am getting some spurious kind of thing so how to solve so that I can feed that RF to power amplifier?
And how to verify RF spectrum on receiver side because if we want to see on received aide then we must out sma to sma cable or wireless antenn then Rx port is nt free so how to check on receiver side??
And what is need of ref_clock port on fmcomms card .will it be helpful to eliminate spurious which I am getting on source side.??
