Me
Not 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
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. 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.
TelequipmenT plugins
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 :-)
-
TQ, TM500 (DC and PG families) and 5000 series connectors compared
-
TQ, TM500, 7000 series and 5000 series profiles compared
Notes to me
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...
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. Will also try `pdfsandwich`
Can extract pages from a pdf
pdfimages --all infile.pdf infile # 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

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.
Experimental pages
475 video links and components
Testing cleaner links to videos and discrete component lookups
User:Qfissler/475-parts-test-page
Formats for big lists of parts
Reminder to test these on mobile and various.
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:

Some scopes, enclosures and plugins
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. | |
| 9 | 7000 | 7603 | 7A18, 7A18 & 7B53A | Engineer says it worked before he stored it but no trace visible now... |
| 10 | 7000 | 7603 | 7A26, 7A22 & 7B53A | |
| 11 | 7000 | 7613 | Opt 6 Spectrum Analyser Graticule, 7A15Ax2 & 7B53N | |
| 12 | 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. |
| 13 | 7000 | R7623 | 7A15A, 7A26, 7B92A & folding rack handles. | My least favourite Tek scope? ...but gives me the 7A26 and 7B92A |
| 14 | 7000 | 7633 | 7A15A, 7A18 & 7B50 | |
| 15 | 7000 | 7633 | 7A26, 7M11 & 7B92A | 7M11 is a hefty beast... |
| 16 | 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! |
| 17 | 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. |
| 18 | 400 | 455 | Pouch, Front cover, manuals | Queued for repair - completely DOA. |
| 19 | 400 | 465 | Pouch, OPT 7 (DC PSU Input) | Queued for repair - no trace. |
| 20 | 400 | 465 | OPT 4 (EMI reduced), OPT 7 (DC PSU Input) | Queued for repair - no trace. |
| 21 | 400 | 465B | Front cover, pouch, manuals, calibration records. | Pristine (bar rear feet) |
| 22 | 400 | 465B | Twitchy - needs service. | |
| 23 | 400 | 465B | Twitchy - needs service. | |
| 24 | 400 | 466 | Analogue storage version of 465 | |
| 25 | 400 | 468 | Storage version of 465B | |
| 26 | 400 | 468 | Damage to A trigger control... | |
| 27 | 400 | 468 | Cover, Op Manual, OPT 4 (EMI), OPT A2 (3 metre power cord with UK plug) | |
| 28 | TDS2000 | TDS2012B | USB version of TDS2012. I'm amazed how accurate it is for frequency readout. I need to take photos for the wiki! | |
| 29 | 2000 | 2215 | Queued for repair: Got this from an engineer who says the trace is distorted. | |
| 30 | 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. |
| 31 | 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. |
| 32 | 2000 | 2445B | Pouch | Queued for repair: Engineer replaced all caps and gave up when it didn't work. Collapsed deflection. |
| 33 | 2000 | 2465 | I'd forgotten I had this - it was in a bundle of things I bought... | |
| 34 | 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. | |
| 35 | 2000 | 2465B | Pouch, OPT 2 (Probe Power) | Queued for repair: RIFA caps + NVRAM (already backed up! Got FRAM replacement to fit.) |
| 36 | 2000 | 2465B | Pouch | My favourite scope! |
| 37 | 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) |
Telequipment
| Model | Options | Notes |
|---|---|---|
| DM63 | I bought this cheap for spares. Hopefully the 155-0056-00 is working so I can complete my 5103N | |
| D67A | Front cover, manuals, calibration records | Immaculate! |
| D75 | Horizontal version of D83 | |
| D83 | I love this for the large screen - same tube as 7403N and 7603 |
I have others... I intend to share more info some time soon.
