Hi all!
I am trying to repair an E4402B.
I already viewed the videos of The Signal Path and verified the integrity of the dividers on the backside of the A8 assembly.
Sadly, these are working correctly.
Also the 600MHz is present and correctly divided 128/129.
The error behaviour is a bit weird to me, i got an unlock and unlevel message only below 700MHz.
When i hit 700 and go above, these errors disappears.
I was also looking over the block diagrams but i really got stuck...
Would really appreciate to find help with this!
Thanks in advance!
Regards,
Alex
