A Tektronix 465 portable analog oscilloscope is a typical instrument of the late 1970s. In the 1960s Tektronix introduced the relatively compact 450 series of portable oscilloscopes, starting with the 50 MHz 453. The 453 was superseded by the 454. There was also a 422 15 MHz AC/DC portable made. [1]
In 1956, a large property in Beaverton became available, and the company's employee retirement trust purchased the land and leased it back to the company. [10] Construction began in 1957 and on May 1, 1959, Tektronix moved into its new Beaverton headquarters campus, [10] on a 313-acre (1.27 km 2) site which came to be called the Tektronix Industrial Park.
Planar was founded on May 23, 1983 [3] by Jim Hurd, Chris King, John Laney and others as a spin-off from the Solid State Research and Development Group of the Beaverton, Oregon, based Tektronix. [4] In 1986, a division spun off from Planar to work on projection technology and formed InFocus .
In July 2015, NetScout finalized its acquisition of the communications business of Danaher Corporation, including Arbor Networks (security systems), Fluke Networks (RF and Wi-Fi network troubleshooting and analytics), Tektronix Communications (traffic inspection, customer experience management and analytics) and VSS Monitoring (network packet ...
Single- and three-phase pad-mounted transformers are used in underground industrial and residential power distribution systems, where there is a need for safe, reliable, and aesthetically appealing transformer design. Their enclosed construction allows the installation of pad-mount transformers in public areas without protective fencing.
Underneath a substation, a mat or grid of conductors laid around 0.5 or 0.6 metres (1 ft 8 in or 2 ft 0 in) underground provides grounding. [ 26 ] [ 27 ] This grid, which is typically copper although it may be galvanized iron in some countries, [ 27 ] is used to ground circuits that are being worked on to prevent accidental re-energization ...
The Xerox Phaser 7700 Series of color laser printers use the VxWorks Operating System on its 20GB PATA IDE Hard Drive.. The 7700 Series is a wide format duplex-capable laser printer capable of printing up to 12x18 page sizes.
Standard Scott Connection 3 φ to 2 φ. Assuming the desired voltage is the same on the two and three phase sides, the Scott-T transformer connection (shown right) consists of a centre-tapped 1:1 ratio main transformer, T1, and a √ 3 /2(≈86.6%) ratio teaser transformer, T2. The centre-tapped side of T1 is connected between two of the phases ...
