Re: EXTERNAL CLOCK REFERENCE PROBLEM
you need to check on U2000 for clocking connection & Quality
if those are good, you have to "tune" the Center DA by add/reduce until deviatioin is around -11dB.
to get clock calculation :
A : (Freq Discremination/1000)*1667
B : A (+/-) Current DA
Note : (+) for -A and (-) for +A
B : Center DA
