Hi all,
Some years ago I've bought a second hand the 492 spectrum analyser (Tek), options1/2/3, with incomplete manuals. Unfortunately the option 1 (calibrated preselection to the 1st mixer for the 1.7 to 18 GHz freq. range) don't work properly. So, I am looking for the block & detailed circuit diagrams(scanned) for that option.
(From my incomplete manual I learned that the preselector circuit have the number 37).
Any help appreciated.

For moderators:
Please don't move my topic to another forum. I think my request is for RF engineers. Thank you.

Hi harlan1,
From the Tek492 I have the complete Operator's manual as PDF (about
35MB). But there are no deep technical info.
But from the Tek494, which is similar in RF path, I have the full Operator's
and servica manuals. Could this help you?
Bye
