Hi all;

 

When i use ADF4150+ADF5901 to creat FCMW signal, i have a questions.

 

The Dev_Offset=LOG10(Fdev/(Fres*DEVMAX))/LOG(2)

 

The Fdev is the Frequency sweep step ,the DEVMAX=2^15,the Fres=Fpfd/2^25

 

when my Fpdf=100MHz,So it means that  my minimum Fdev is 97KHz or the Dev_Offset is a negative number.

 

So does my minimum frequency step is 97KHz in these conditions?

 

Look forward for your reply.
