Hi folks,
?
my 8510C system recently developped an unlock error, so I have checked the source HP83651A first.
It turns out, that the source output below 2,4GHz is exactly (to the Hz) 100MHz too low, while above 2,4GHz it is spot on.
Also, the 8510C works fine above 2,4GHz.
Has ever anybody seen such a strange problem? Any ideas what could cause this?
?
Tom
