Does anyone have a paper copy of the 3325B Service manual? We only have the pdf that was scanned in on agilents website. We are trying to test the U119 on the A26 board. Not able to get to it and can't read which chip it shows that it goes to on the PDF. Any help would be appreciated.
Found a small mention of it on the interface troubleshooting section.
Looks like it puts out 4 MHz sq wave or pulse on pin 8 that is fed to pin 12 of U109.
