content: Hi all.I'm hoping someone can postpage 8-13from the HP 3457A service manual P/N 03457-90012 (February 1988 Edition 3).I'm asking because this page is missing from the scanned PDF available from the Keysight website at:http://www.keysight.com/main/facet.jspx?&cc=AU&lc=eng&k=03457-90012sg&pSearch=tnmSearch&hasLuckySearch=trueAccording to the table of contents,page 8-13is the start of chapter8-31. A/D Converter.This is the first page of the detailed theory of operation section for the A/D converter which might help me with fixing a failed self test AUXERR#8 integrator convergence error.Any help would be appreciated. Thanks.

content: Hi Johnny10. Thank you for posting the link but it is exactly the same PDF file as I got from Keysight and I have checked and confirmed that it is also missing page 8-13.Perhaps someone has a hard copy of the service manual that they can scan just thatsingle page 8-13for me?

content: The 47.4MB one comes from Agilent site and doesn't contain that page. There are smaller ones which don't contain the page either (and are missing a bunch of other pages too.)There's this 138MB one from elektrotanya, which has 30 fewer pages than the 47.4MB one so it may have come from a different source:https://elektrotanya.com/hp_3457a.pdf/download.html

content: Maybe you could ask Agilent... perhaps the page was missing since the beginning, because for at leats two independent scans to not have that page seems odd.

content: Quote from: AlfBaz on August 31, 2017, 12:32:02 amThanks Alf but that's not it. 03457-90011 is an older version of the manual (Edition 2, May 1986). I was after page 8-13 from 03457-90012 (Edition 3, February 1988) which was stated in my original post.Anyway, I have purchased a scan from Artek so I now have the missing page I was looking for.Thanks to everyone who responded. It is appreciated.

content: Quote from: AlfBaz on August 31, 2017, 01:16:35 amDave at Artek was very quick to turn around my order, so impressed with that. The scan I received is generally good but unfortunately the big schematic on page 8-73/8-74 needs more resolution. The smallest annotations are illegible. I can't make out some of the IC pin numbers for example. JPEG style compression artefacts in the scan make the small font used by HP too fuzzy to read.

content: Quote from: anderoo on August 31, 2017, 01:41:21 amDave is always receptive to feedback. Go back and tell him exactly what you just mentioned and ask if there's anything he can do about it. Most of the manuals he has available in pdf are backed up by the original paper. He might well be able to re-scan those elements at a higher resolution.The other option is of course the schematics are broken up but very legible in the freely available manual found on-line.
