I am using a ADF4150HV and I notice the synthesizer output has a spurs at about 500Hz offset from the LO. I use the phase resync features and able to attenute the spur from 45dBc/Hz to 70dBc/Hz. The phase value that I use is 100, and it is a number I picked with tried and error. My question is why using the phase resync in this case help reduced my spurs?
Thanks so much!
