Hi, ADI friends
I do some test as below:
My question is :
Why there is big influence to TX signal's spectrum when change the RxLo frequency?
TxLo=1.3Ghz , RxLo=1.3Ghz Tx baseband=1Mhz, The spectrum as below, it looks OK.
Then I change RxLo=1.30001Ghz, TxLo still in 1.3Ghz, but the spectrum as below :
Then I change RxLo=TxLo=1.30001Ghz the spectrum as below:
Last test RxLo=1.3Ghz, TxLo=1.30001Ghz, the spectrum as below:
