Hello,

 

i got a problem with my ADF4360-4. The Phase-Locked Loop dosen't go in lock. You can see it on the picture. Yes, I know it's not the best quality, but I hope the most importend things are visible.

The PLL should work by a Frequency of 1,532 GHz. The calculation for the Loop-filter and the picture is in the attachment.

The values for the latchs are:

 

R Latch: 21 DE 32

Control Latch: 4F F5 28

N Latch: 34 03 21

 

I use this configuration on an other ADF 4360-4 and I works great.

 

I hope anyone can help me.
