I could very well be that there is indeed a upgrade in PLL sensitivity or Sweep ADC. I can't open the 85102C as it is borrowed, but it is very interesting to understand the differences/improvements.
Does anyone has the schematics of this:
A20 Sweep ADC????????? 85102C - 85102-60234
A23 Main Phase Lock ?85102C - 85102-60227
Or has anyone perhaps these boards surplus ?
?
I will al;s look to this capacitor.
