[Moon] Manual and/or schematic for Systron Donner synthesiser ?

[SM2BYA, Gudmund]

Hello all,

Does someone know where I can get hold of a manual and/or schematic for 
the Systron-Donner 17208-S4018?

This is a 100 MHz - 18 GHz  microwave CW synthesiser, about 20 years 
old. I got one a couple of weeks ago, alas without a manual. Right now 
it works fine to at least 12 GHz (that's where my counter stops), but if 
anything should happen to it later on, I wouldn't know where to start 
looking without the manual...

Thanks,
Gudmund SM2BYA
