Maybe someone here has an original one, and would be willing to scan it for you for a small fee.
Or, if it’s not urgent, you could always wait for one to pops up on eBay or another auction site. I don’t know how often they do, though.
Sorry I can’t be of anymore help.

There are pobably others out there.

I assume you’ve checked Artek manuals?

http://artekmanuals.com/

They are not free, but what you get is a very high-quality PDF.

That is true.

There are also the Davmar, KO4BB, Barrytech, kahrs.us and other sites (my apologies to the owners of those sites for my declining memory) which sometimes offer different information, including non-Tektronix instrument resources.

What, no snappy retort to put me in my place?

You talk about redundancy like it's a bad thing. Lemme tell you about redundancy:
It gives you error detection and it gives you fault tolerance. And a search function is
only as good as the nature and consistency of the data set you're searching within,
which in the case of 7000 not-particularly-organized contributors is always going to
be less than stellar.

So taxonomy and hierarchy are your best friends if you want to have a hope of finding
what you're looking for without extensive, repetitive, and increasingly-speculative
searching in a big flat swamp of files and directories. And if you think that's somehow
superior to having a directory called "465", then you're in possession of some new
magic which has not yet been brought to my attention.

Now, I don't claim to know everything about the capabilities of the groups.io system,
but what I do know is that they provide a blockheaded and ham-handed set of tools that
constantly presents new surprises in what it *can't* do, for example, the inability to
create a file hierarchy in the photos section or to cleanly embed a link in the files section.

I could go on, but I think I've made my point.

Re: Tek 4041 GPIB Controller

Monty McGraw
 

I just added eight service notes in a new folder for the Tektronix 4041 on my github repository: https://github.com/mmcgraw74/Tektronix-4041-GPIB-Controller/tree/master/4041_Service_Notes

One of the notes discusses the difference between v2.0 firmware and v2.1 firmware.

I extracted these notes from ServiceTekNotes I found at http://w140.com/tekwiki/wiki/Tektronix_Magazines

Re: 2432A Chan Delay adjustment

Roger Evans
 

Peter,

I don't have direct experience of this but typically an amplitude of 1V or so and PRF of 1kHz - 1MHz would be fine. The scope is looking for a well defined (in time) trigger point and comparing the actual position of the trace on screen with where the calibration software thinks it should be. You would need a risetime in the 1ns region, possibly 2ns would be OK.

Regards,

Roger


Re: 2432A Chan Delay adjustment

Peter K
 

Thanks for the answer.
I did not find anything like the one described.
There is a video with this procedure in youtube for 2430:
https://www.youtube.com/watch?v=O8Ig3QeHfm4
It seems that 2430 don’t need chan delay adjustment.
I just want to know what signal the scope expected from signal generator to pass this routine. SM only says to set the Calibration Generator (PG506) for fast rise output.


Re: Tektronix 2230

Hi satbeginner
Now I confirmed that my measuring oscilloscope probe is in 1× mode.
Volt/div is 500mv. I get roughly 1.5v at gate of FET with respect to tp940.
I have attached the photo. What might cause the voltage so much I do not under stand.
Even at pin5 of u930 I am not getting the voltage as expected.
In your 2215 measured voltages are v peak to peak or v max referenced from 0.
I am stuck.
What to do?
Thanks saroj


Re: OT - Any interest in starting a Tektronix Logic Analyzer Group? (with added bonus question!)

jslcanuck
 

Only the group's owners can sort it out, and of course they are far too busy.
Nobody else has the necessary permissions, except the people who uploaded the
original data in each case.

You don't seem to know much about how these groups actually work.
I'm smiling, but there are undoubtedly a number of members of this group who are
also members of the other group I alluded to, who know what I've been doing over
there for the last year or so, and who are laughing like hell at you right now for that
bellicose declaration.

No, you don't need to be a group owner to manage files. You just need "moderator"
status and you can push the files around all you want. Any one of the nearly 7000
of you could do it... if anyone cared to, and the group owner(s) trusted you.

Hard to

And given the existence of the search function, a neat hierarchy of directories isn't actually required. Taxonomy is basically redundant these days,
