Hi,
I am transmitting and receiving and sinewave with FMCOMMS5: the received sinewave appears at -10dBFs while the noise floor is consistently around -73dBFs (16K FFT , Fs=50MHz) or equivalently :-107dBFs/Hz. The gain is set to full gain (71dB). Noise floor is very similar in all bands. Looking at some published PSD plots the noise floor should be MUCH lower.
Can you please provide some explanation/solution to the problem ?
thanks.
