Re: HP Agilent 8753ES VNA repair [Help]


 

PLL 2 is 977 KHz instead of 996 Khz. I have a delta of 19 KHz on PLL on high band. This explain why the IF on A10 is 23 KHz instead of 4KHz and do not pass the digital filter.?
?
Problem is common on high and low band. Do you have an idea on where to look at now ??
