I have here a HP 8341A signal generator which has a bad YTO. A55, the YO Driver, is also faulty, but I have found a spare part and ordered it. The YTO in question is a 5086-7323, which works from 2.3 to 7 GHz. I wonder whether it is possible
a) to repair this YIG,
b) or to test it somehow outside the instrument,
c) or if there is any spare part or a similar replacement?
It would be great if I could, somehow, bring the signal generator back to life.
Many thanks for any hints,
