We have pages for over 2,000 products, 1,600+ patents, 700+ components, 300+ key people, and more.

We also keep some 6,000 PDF documents – manuals, catalogs, specifications, data sheets etc.

In addition, you can find 18,000 images such as equipment photos, and over 1,000 ROM images and software packages here.

Welcome to TekWiki, a wiki for the community of Tektronix oscilloscope enthusiasts.

The purpose of this website is to help people get information about classic Tektronix equipment. You don't need an account if you just want to read pages and download files.

There is nothing for sale here. This site is not affiliated with the company Tektronix; it was built purely by volunteer effort.


To find what you need, you can browse the various tabs on the top of this Main Page where most instruments are listed, e.g. the "Tube Scopes" section. We also have visual index pages for important series of instruments that help identify instruments from photos.

Even easier is using the "Search TekWiki" box on the top of the page, e.g. to locate instruments by type number.

The manuals stored on this site are named following their Tektronix part numbers. They are indexed on the Manuals page and always linked to the respective instrument's page, so it is easiest to start from a specific model's page.

Every now and then you may find a red link on one of our pages – this means that the linked page has not been written yet, or we do not yet have a copy of the linked document. If you have any helpful information, please see below.


If you want to add to TekWiki or improve existing TekWiki pages, please email the administrator for an account.

We have some guidelines for contributors that can help you understand how we structure this wiki.

Tektronix started producing oscilloscopes with the model 511 in 1947, at which time the vacuum tube was the primary active device, and remained so into the 1960s.
While transistors were used increasingly in such instruments from the mid-1950s on, this section contains instruments and instrument families primarily based on vacuum tubes (aka valves).

Major families of Tektronix oscilloscopes from the tube era include:

160 Series

Monolithic Tube Scopes

500 Series

500-series oscilloscopes

500-series (Letter-series and 1-series Plug-ins)


Third Party

560 Series

560-series oscilloscopes

560-series plug-ins

560-series Accessories

Sampling and Automated Measurement

Third Party

580-series oscilloscopes and plug-ins

647-series oscilloscopes and plug-ins

Third Party

661-series oscilloscopes and plug-ins

From the late 1960s on, Tektronix produced oscilloscopes that were predominantly solid-state based except for the CRT.

Major instrument families from this period included

2000-series oscilloscopes

2600-series instruments


5000-series oscilloscopes

5000-series plug-ins

Third-Party 500-series Equipment

5030-series oscilloscopes


7000-series oscilloscopes

T900-series oscilloscopes

TAS-series oscilloscopes

The Tektronix TM500 is a modular test equipment system offering a variety of plug-in modules that fit a dedicated series of mainframes with one to six module slots. The plugins are not compatible with other Tektronix lines such as oscilloscopes.

The TM5000 series, introduced in 1982, added a GPIB interface on the mainframe to control intelligent plugins.

Telequipment was a British oscilloscope manufacturer that was acquired by Tektronix in November of 1966.


Keithley Instruments merged with Tektronix in 2010.
