Curve tracers[edit]

A notable omission from this article is that Tektronix pioneered the manufacture of the curve tracer for testing transistors and other semiconductor devices. It's my intention to create a page about curve tracers. DFH 18:57, 26 September 2006 (UTC)

Done. I substantially expanded an existing article. See Semiconductor curve tracer and, of course, feel free to be bold and expand or correct the article.

Fair use rationale for Image:Tektronix logo.jpg[edit]

Nuvola apps important.svg

Image:Tektronix logo.jpg is being used on this article. I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in this Wikipedia article constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.

Please go to the image description page and edit it to include a fair use rationale. Using one of the templates at Wikipedia:Fair use rationale guideline is an easy way to insure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.

If there is other other fair use media, consider checking that you have specified the fair use rationale on the other images used on this page. Note that any fair use images uploaded after 4 May, 2006, and lacking such an explanation will be deleted one week after they have been uploaded, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you.BetacommandBot 04:02, 6 June 2007 (UTC)

No longer publicly traded under NYSE: TEK[edit]

I didn't know if the ticker symbol TEK should have been replaced with DHR, or just removed altogether.

Discuss. —Preceding unsigned comment added by (talk) 01:03, 26 November 2007 (UTC)

Triggered oscilloscope citation[edit]

The article calls for a citation to substantiate the invention of the triggered oscilloscope. Please see:

for an appropriate reference.

As a retired officer of this company, I choose not to make the edit myself, but to place it here for verification by others.

Thanks for the info, I have added the citation. Also thanks for following the conflict of interest guidelines. Aboutmovies (talk) 00:47, 10 December 2007 (UTC)

This page is turning into a puff piece.[edit]

It should read like It is devolving into an annual report. (talk) 17:42, 8 July 2008 (UTC)

4300 series and UTek[edit]

Tektronix also used to make graphic workstations running UTek (4.2BSD clone). sendmoreinfo (talk) 19:22, 17 November 2008 (UTC)

Airport closing not reason for land availability[edit]

Text in the article reads: "In 1956 a large piece of property in nearby Beaverton became available with the closing of the Bernard Airport, and the company’s employee retirement trust purchased the land and ... etc."

Not true. The airport remained in operation until 1969. See: —Preceding unsigned comment added by Other Hand (talkcontribs) 01:58, 29 January 2009 (UTC)

I was at Tek from 78-83[edit]

Just saying... if someone wants to add it, since I'm already notable enough to have a WP page. --Randal L. Schwartz (talk) 19:47, 2 March 2012 (UTC)

Inventor of triggering?[edit]

In this document, which is used as a reference for this article, the author states (footnote, page 15): The current Wikipedia entry says: The company's founders C. Howard Vollum and Melvin J. "Jack" Murdock invented the world's first triggered oscilloscope in 1946, a significant technological breakthrough. The Dumont 248 circuit description clearly refers to triggered operation, so this is a questionable claim. The statement is supported by a source, but to me this particular source seems more solid. I suggest removing the claim. Wammes Waggel (talk) 12:57, 5 December 2014 (UTC)

I'm unable to download scope-history.pdf. My reading of Oscilloscope history#Triggered sweep is that the Dumont 248 had an external "driven" rather than an internal "triggered" sweep. The distinction being an external drive pulse started the sweep rather than the scope extracting the drive signal from the input. The applications of driven sweeps (such as radar) would have an easily available drive pulse. Glrx (talk) 23:46, 6 December 2014 (UTC)
Dumont Type 248 adverisement on page 39. Scope uses Z-axis modulation to show time.
Here the driven (or "slave"') sweep is triggered by the pulse itself, which is then delayed by a self-contained distortionless network so that the leading edge is not obliterated. The one microsecond markers (or others at intervals of 10 or 100 microseconds) are blanked into the trace by an internal marker oscillator. A beam-control circuit eliminates the bright spot of the beam rest position.

puff piece[edit]

This reads like a promotional pamphlet from the company.

"These scopes were outstanding performers often preferred over their laboratory bench models. The first models were the 422, a 16 MHz bandwidth and the 453, a 50 MHz bandwidth model. The following year the 454, a 150 MHz portable.[10] These models put Tektronix well ahead of their competitors for years. The US Military contracted with Tektronix for a model 453 "ruggedized" for field servicing. The 400 series models would continue to be popular choices in the 1970s and 80's. In addition the styling of the 400 series would be copied by Tektronix's competitors. 400 series oscilloscopes are still being used currently.[11]"

The whole article reads like this. It's got valid information in there, but a lot of "probably the world's first" type weasel words and unnecessary promotion. (talk) 13:06, 17 December 2014 (UTC)
