When i use ADF4150+ADF5901 to creat FCMW signal, i have a questions.
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.
Hope your help, thanks.
For smallest frequency step set DEV=1 and DEV_OFFSET=0. When Fpfd=100 MHz.
Fdev=(100 MHz/2E25)x1 = 2.98 Hz.
