Systron Donner SD764 service manual
Hello to all,
I'm trying to repair a Systron Donner Spectrum Analyzer, model SD764.
It is the military version ( I think ) and it's working with some
difficulty and measuring errors.
Anyone know where to find a service manual, even willing to pay for ???
I'm also trying to find the ENGLISH manual of Rohde&Schwarz *ZWA*
Wobbler . It is an ancient Vector Analyzer ( 1968 vintage ).
I do have original GERMAN manuals, but my knoledge of this language
is nil !!! :-(
Seems fully functional, but... without understandable instructions
I'm lost .
You can reply also directly, my mail is valid.
Thanks for any help furnished, cheers de I5SPO, Piero.
