I used the Evaluation/Development System EV-ADF4159EB1Z to evaluate the component ADF4159.
I could use this ADF4159 in the realization of a FMCW radar.
Using the default values, without any modulation ,I saw the picture in the attachment on the spectrum analyzer ANRITSU MS2725C in burst mode acquisition. I see it as a modulation burst around the carrier.
Then I tried to set a fsk modulation but I did not get any results.
I only managed to change the carrier frequency.
My question : what I saw is it correct or the evaluation board is not working properly?.
