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

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.

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.

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.

~~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:

Tektronix

Tektronix
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.

10	7000	7603	7A18, 7A18 & 7B53A	Engineer says it worked before he stored it but no trace visible now...
11	7000	7603	7A26, 7A22 & 7B53A
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.

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 1200C01 RS-232 Comm Pack 12RC01 Printer Support ROM Pack 12RM25 Disassembler ROM Pack (Motorola 68000) 12RM99 Custom Mnemonics ROM Pack TMS32020 Opt 11 12RS01 8K RAM Pack	No POST. No battery damage.
