Hi,
today I got a HP 8559A spectrum analyser. Unfortunately the
input stage seems damaged (every thing works, but I do not see
any change in the display when I apply a signal - only noise).
It can display a range of 3GHz at once (and with mixing up to 21GHz).
What do you think? Are there any chances that I can repair
the input stage myself? I have not opened it yet, but I guess
there are some hard to get parts inside, and I do not have any
circuit diagrams. Anyone here with some experiences in this field?
thx in advance,
Matthias
