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 The 453 was superseded by the 454.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.
A planar transformer Exploded view: the spiral primary "winding" on one side of the PCB (the spiral secondary "winding" is on the other side of the PCB) Manufacturers either use flat copper sheets or etch spiral patterns on a printed circuit board to form the "windings" of a planar transformer, replacing the turns of wire used to make other ...
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 .
A "transformer bank", widely used in North America: three single-phase transformers connected to make a 3-phase transformer. The low-voltage secondary windings are attached to three or four terminals on the transformer's side. In North American residences and small businesses, the secondary is often the split-phase 120/240-volt system. The 240 ...
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 ...
A capacitor voltage transformer (CVT), is a transformer used in power systems to step down extra high voltage signals and provide a low voltage signal to the actual VT (voltage transformer) used for operating metering/protective relays due to a lower cost than an electromagnetic PT. The circuit diagram for a simple capacitor voltage transformer
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 ...
