Hello all,
I have a Tektronix 2465B that powers up with the following
error code:
CT TEST 84 FAIL 0C
Looking at the service manual I cannot find this particular
code. I
figure that I'm mis-interpreting the code somehow. Can
anyone shed a
bit of light for me?
Thanks.
CT is counter-timer,an option that has a separate service
manual.
It probably will be hard to find one.
there also was a pricey extender kit for servicing the
options.
(they plug into a options board on the top of the scope
chassis)
You can probably make your own extender ribbon cables.
also,there will be a sticker on the back of the scope telling
you what
options are installed,if any.
there also were scope handle stickers like "2465B CTS" or
2465BDM"
Thanks very much Jim (and robb and PeterD). If I can't repair
the
option, would you happen to know if it's possible to just
remove it and
have the error go away?
i think you can by pass the error with a combination button press
, i.e. hold three certain buttons and scope bypasses but i do
not know affect on the performance and operation ?
Yeah I know, but this failure for some reason was causing intermittent
sweep problems.
also there is a way to do a option calibrate or reset or clear
??? using some menu but my memory fails me
I couldn't find anything in the 2465B service manual about this. Oh
well...
i am sure someone else can help with that,
hope you fix it

Go to bama.sbc.edu (or the mirror site), there you can download a
manual with schematics, all error information, etc.
hth,
Andreas
For the OPTIONS?
The options all came with separate service manuals.( a royal PITA)
And I believe they are kinda hard to come by these days.
When I think of all the TEK manuals tossed out when the Orlando Service
center closed...I coulda been RICH,if only I had had a place to store all
of them.
