It occurs to me that, if I am going to unbind my 7934 manual (re-binding is
a pain) to scan pages 6-22 and 6-23 in order to update the copy on TekWiki,
it would be useful to know if there are any other pages missing from the
online copy. This would require someone to go through the online manual
page-by-page to verify that those two pages are the only ones missing. I
don't have time to do that right now. If someone is willing to do that,
please let me know ASAP.

I should probably update the PDF of the manual on the TekWiki site. That'll
take a bit longer.

I have been skimming this thread, since I have a 7934, but not really
paying close attention to it.
I have an original 7934 manual from Tektronix, dated May 1986. It does
have
pages 6-22 and 6-23. I can scan and upload them or send them privately.
It'll take me a day or two to do that.

After looking at 3 totally different scans of the same printing of the
7934 manual I don't believe that pages 6-22 and 6-23 were in any
manuals
from the first printing. My three scans show file sizes of:
1. 112,361 KB Title "7934 Oscilloscope (1986) WW.pdf" 464 pages
long
2. 210,637 KB Title "7934.pdf" (SECURED)
470 pages long
3. 72,903 KB Title "Tektronix-7934-service,user-ID2530.pdf"
501
pages long
#3 in the "schematics" section, the pages have been scanned 1/2 page
at a
time for those pages that were probably "B"size in the original manual.
In
some cases they were scanned in 1/3 page at a time.
#2 in the "schematics" section the pages are scanned the whole page at
a
time.
#1 same as #2.
There are other differences in the "schematics" sections with sizes of
the
pages, when I go through the pages at the same magnification settings
of
the Adobe Reader. #2 has some protection applied and is "SECURED". I
can't use the "Snapshot Tool" from the "Tools" menu. In one scan I can
see
the holes for the spiral binding which the others don't have on the
same
page. There are other differences on the placement of some texts. But
that could be from the scanning process. I don't know.
My conclusion and best guess is that, believe it or not, Tektronix did
NOT
print those missing pages in the first printing dated "May 1986".
GASP!
There are pages of "CHANGE INFORMATION" in the back of each scan. One
shows signs of being stapled while others don't show this.
However is anyone can find those missing pages please scan and post
them.
