Hello everyone,

 

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!

Weng
