I might not be entirely neurotypical...

...and I sometimes apologise.

I like to break paragraphs into punchy statements - and I think that many others do.

I like to quote

text from the Tek manuals as fixed font blocks

...separate from the paragraph.


Playing with formatting. Maybe I'll try some other skins and using mobile to see why some formatting is preferred over others

Born in London & based near London, UK.

Been using Tek scopes for many, many years.

I own a couple of scopes not on this wiki


Notes for other users

Plugin Interfaces

Not sure if these photos have a place on the main wiki - the 7000 series are a lot deeper and a fraction wider. The TM500, 5000 series and Telequipment plugins share the same chassis glide extrusions - but locations and widths of the glide keys and pins on the backs of the plugins prevent mishaps :-). The 11000 series is almost identical to the 7000 series but for the top optional connector which is shaped to prevent plugging into the wrong frame.

The TM500 and 5000 series interfaces are very similar to the JAMMA (Japanese Arcade Manufacture Marketing Association) but some connections are paired and some have a notch which removes a connection position.

Connector summary

The various mainframe and plugin interfaces have different pitches to keep us on our toes.

TelequipmenT Type 43

I've got a manual for the TelequipmenT Type 43 (D43/D.43/D.43R/S.43) which is from 1965, the one on this wiki is newer - I think that mine is from before Tektronix bought Telequipment. The one I've got has appendices for plugins D, G and H which are not in the 1968 printing. I see that there might be separate manuals for the plugins on the wiki - I've not checked all three but I see that my appendix for the H plugin has different content. All I've spotted so far is that the one on the wiki doesn't list all of the transistors (though the schematic shows the types) and is missing the two variable inductors, L21 and L22, which are listed as:

2.2/5.1μH Variable Inductor (Brown/Yellow)

I might add this to the H plugin page or its Discussion section.

Repair notes

Some notes for going to other pages when completed.

LiL cells

I have Lithium Iodide cells in a 1240 and its 12RS01 RAM pack. Stamped 1983 and still showing 2.75 V in circuit with some bulge... I think that cell will get its own page for linking from the various device pages which contain one.

Notes to me

Wiki editing

Header Tabs

Table Generator

Have a look at this link! Visual table Generator! If you see a table you want to edit, copy the rendered table from a page viewed in your browser (ie drag to select&highlight, then copy with Ctrl-C or right-click, copy) and paste it into the editor ("File", "Paste table data...") - from there, you can transpose/pivot and transform the table!

Parts

I've got a few notes re parts refs and BOMs for various scopes - I want to collate and present them here eventually. I found a couple of useful sources and need to be able to find them when I want them... This wiki is perfect for that.

I have over 1800 parts refs, many with generic part refs for ordering. I'll not share them until I improve them (some conflicting info needs cleaning/refinement).

Screws

In the UK, UNF and UNC threads are relatively rare and expensive with metric being the norm.

Wiki style hints

I need to remind myself to refer to the style guide for this wiki:

Tekwiki_Guidelines


Working with PDFs

Extracting Part Refs

I had fun extracting lists of references to the 151-0367-00 transistor from the 475 service manual.

Get the text from the manual

$ pdftotxt 475_SM.pdf 475_SM.txt

The tables are split but remarkably consistent so it's not too difficult to work back and pick up the previous column

$ grep -B12 151-0367 475_SM.txt

Grab the refs I want and paste them into a text editor, then turn new lines into comma space...

I'll come back to this - I intend to simplify extraction of parts lists and other info (eg Manual change appendices) from the manuals so we can have useful cross reference and more.

OCR

The upload tasks page recommends that we overwrite a PDF if we OCR it - then all existing links would continue to work. I think that we should share more info about good OCR methods as mine seemed to be less good than ones I download from this wiki. I'll share notes about what works for me...

`ocrmypdf` seems to work very well - the recognised text lines up with the image text - best results so far.

Can extract pages from a pdf

pdfimages --all infile.pdf infile-extracted    # the last argument there is the prefix for the output file names

Remove any duff pages, rotate any pages which are better rotated, then img2pdf and ocrmypdf and then rebuild the pdf

Create PDF for images

$ img2pdf *.jpeg  --output T940-letter-June-1983.pdf

Running OCR

$ ocrmypdf T940-letter-June-1983.pdf T940-letter-June-1983-OCR.pdf

Manuals

It turns out that I have a couple of manuals for which there were no scans on this wiki.

I've scanned two already but results could be better. I'll sort out a flat bed scanner in the coming months.

I have a 24 page guide for interfacing the 2445 and 2465 Option 10 - I'll look for it online or scan it and save it here. Opt.10 Instrument Interfacing Guide

I have the Ops Manual for the 1200C01 070-4343-00 and 1983 corrections C1/783 - will scan within months.

Another to do is the 7603 Operators Instruction Manual 070-1310-00.pdf - left reference here to remind me and opportunity for anyone to prod me in case they need it. Done

Fractions

I learned recently that the thickness of the 7000 series plugin PCBs (and presumably others) is ⅟16". There's no unicode symbol for that so I thought I'd try and take note of these options:

idx Series Model Options Notes
0 5000 5103N D12 Dual beam display module. Missing plugins. Strange light mark on CRT/implosion guard.
1 5000 5103N D12, 5A18N, 5A22N, 5B12N and all five manuals to suit. Near immaculate. Close inspection reveals that the 5B12N is missing a chip! 155-0056-00 sweep gen / trigger - so the 5B12N is no longer a dual timebase...
2 TM500 TM501 Seems to work OK.
3 TM500 TM503 Seems to work OK. Missing top cover.
4 TM500 TM506 Option 7 Seems to work OK.
5 TM500 PG501 Will service and calibrate this soon.
6 TM500 DC503 Needs repair but mostly working. Completely worn print on five of the ten buttons.
7 TM500 FG504 No power...
8 TM500 PG506 Will service and calibrate this soon.

12 7000 7613 Opt 6 Spectrum Analyser Graticule, 7A15Ax2 & 7B53N
13 7000 7613 7CT1N Latest purchase. Very pleased to own a CT! Focus drift on warming up. Modified case for trim pot access (astig. and focus), auto erase switch, and window for access to left-most plugin.
14 7000 R7623 7A15A, 7A26, 7B92A & folding rack handles. My least favourite Tek scope? ...but gives me the 7A26 and 7B92A
15 7000 7633 7A15A, 7A18 & 7B50
16 7000 7633 7A26, 7M11 & 7B92A 7M11 is a hefty beast...
17 7000 7704A 7A18, Cal Fixture, 7D15 & 7B53A Oh dear - moisture damaged - and the engineer who'd owned it had failing sight - so there's a bit of damage to undo... A couple of interesting plugins!
18 200 222PS Carrying bag, pouch with probes as new, ops manual. Pristine! Works well. Needs replacement battery pack - I have LiPo and NiMH to play with.
19 400 455 Pouch, Front cover, manuals Queued for repair - completely DOA.
20 400 465 Pouch, OPT 7 (DC PSU Input) Queued for repair - no trace.
21 400 465 OPT 4 (EMI reduced), OPT 7 (DC PSU Input) Queued for repair - no trace.
22 400 465B Front cover, pouch, manuals, calibration records. Pristine (bar rear feet)
23 400 465B Twitchy - needs service.
24 400 465B Twitchy - needs service.
25 400 466 Analogue storage version of 465
26 400 468 Storage version of 465B
27 400 468 Damage to A trigger control...
28 400 468 Cover, Op Manual, OPT 4 (EMI), OPT A2 (3 metre power cord with UK plug)
29 TDS2000 TDS2012B USB version of TDS2012. I'm amazed how accurate it is for frequency readout. I need to take photos for the wiki!
30 2000 2215 Queued for repair: Got this from an engineer who says the trace is distorted.
31 2000 2445 Pouch. Queued for repair: Got this from someone who said it worked 8 years ago. Needs PSU caps and more. Row of knobs below CRT all smashed.
32 2000 2445A Pouch, front cover. Queued for repair: Got this from an engineer who says it has been on Royal Navy tour to The Falklands. Pristine front panel.
33 2000 2445B Pouch Queued for repair: Engineer replaced all caps and gave up when it didn't work. Collapsed deflection.
34 2000 2465 I'd forgotten I had this - it was in a bundle of things I bought...
35 2000 2465 Bought for spares! I was told that channel 1 & 2 didn't work. On inspection, I can see that the impeller was removed as the shaft grip was broken. That's likely to mean that the chan 1&2 failure was caused by overheating - and I'd not expect U800 to have survived, either.
36 2000 2465B Pouch, OPT 2 (Probe Power) Queued for repair: RIFA caps + NVRAM (already backed up! Got FRAM replacement to fit.)
37 2000 2465B Pouch My favourite scope!
38 Waveform Monitors 1485C Dual-standard Television Waveform Monitor. Wondering what to do with this... not useful with modern television signals... Maybe restore, take photos, put on display... Scope Clock? (external module - leaving it intact)
39 Logic Analysers 1240 Manuals
