Wavetek
Wavetek was an electronic test equipment manufacturer that made function generators, signal generators and service monitors. Although Wavetek did not invent the function generator, it made them commercially popular. The company's swept RF/microwave signal generators of early 1980's were virtually unmatched in component quality and had user interface features that included a birdy marker system for frequency counting, automatic level control, remote interface port, and front panel designed for quick and simple user control. Following obsolescence, the company technology eventually devolved into lower cost digital instrumentation. History Before Terrence Gooding, president and CEO of Wavetek, took Wavetek private in 1991, the company had 800 employees, 260 of whom worked in San Diego. The company had plants in the US states California, Florida, Indiana, and New York. It had overseas locations in Germany, Hong Kong and the United Kingdom. In 1998, Wandel & Goltermann purchased W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JDSU
JDS Uniphase Corporation (JDSU) was an American company that designed and manufactured products for optical communications networks, communications test and measurement equipment, lasers, optical solutions for authentication and decorative applications, and other custom optics. It was headquartered in Milpitas, California. In August 2015, JDSU split into two different companies – Viavi Solutions and Lumentum Holdings. History Uniphase was started in 1979 in a San Jose, California garage, and made lasers for chip makers and scanners. In 1981, JDS Optics was founded in Canada by Philip Garel-Jones, Gary Duck, Jozef Straus, and Bill Sinclair. The "JDS" is short for Jones, Duck and Straus/Sinclair. The company became JDS Fitel when it formed a partnership with Fitel, a fiber optic and optical connector company. In 1999, JDSU was formed by the merger between JDS Fitel and Uniphase, and it became known as JDS Uniphase subsequent to the merger. Three other major fiber companies wer ...

Function Generator
In electrical engineering, a function generator is usually a piece of electronic test equipment or software used to generate different types of electrical waveforms over a wide range of frequencies. Some of the most common waveforms produced by the function generator are the sine wave, square wave, triangular wave and sawtooth shapes. These waveforms can be either repetitive or single-shot (which requires an internal or external trigger source).cnx.org - Using a Basic Function Generator 2005-08-21 Another feature included on many function generators is the ability to add a . |

Signal Generator
A signal generator is one of a class of electronic devices that generates electrical signals with set properties of amplitude, frequency, and wave shape. These generated signals are used as a stimulus for electronic measurements, typically used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices, though it often has artistic uses as well. There are many different types of signal generators with different purposes and applications and at varying levels of expense. These types include function generators, RF and microwave signal generators, pitch generators, arbitrary waveform generators, digital pattern generators, and frequency generators. In general, no device is suitable for all possible applications. A signal generator may be as simple as an oscillator with calibrated frequency and amplitude. More general-purpose signal generators allow control of all the characteristics of a signal. Modern general-purpose signal generators will have ...

The San Diego Union-Tribune
''The San Diego Union-Tribune'' is a metropolitan daily newspaper published in San Diego, California, that has run since 1868. Its name derives from a 1992 merger between the two major daily newspapers at the time, ''The San Diego Union'' and the ''San Diego Evening Tribune''. The name changed to ''U-T San Diego'' in 2012 but was changed again to ''The San Diego Union-Tribune'' in 2015. In 2015, it was acquired by Tribune Publishing. In February 2018 it was announced to be sold, along with the ''Los Angeles Times'', to Patrick Soon-Shiong's investment firm Nant Capital LLC for $500 million plus $90 million in pension liabilities. The sale was completed on June 18, 2018. History Predecessors The predecessor newspapers of the ''Union-Tribune'' were: * ''San Diego Herald'', founded 1851 and closed April 7, 1860; John Judson Ames was its first editor and proprietor. * ''San Diego Sun'', founded 1861 and merged with the ''Evening Tribune'' in 1939. * ''San Diego Union'', found ...

Los Angeles Times
The ''Los Angeles Times'' (abbreviated as ''LA Times'') is a daily newspaper that started publishing in Los Angeles in 1881. Based in the LA-adjacent suburb of El Segundo since 2018, it is the sixth-largest newspaper by circulation in the United States. The publication has won more than 40 Pulitzer Prizes. It is owned by Patrick Soon-Shiong and published by the Times Mirror Company. The newspaper’s coverage emphasizes California and especially Southern California stories. In the 19th century, the paper developed a reputation for civic boosterism and opposition to labor unions, the latter of which led to the bombing of its headquarters in 1910. The paper's profile grew substantially in the 1960s under publisher Otis Chandler, who adopted a more national focus. In recent decades the paper's readership has declined, and it has been beset by a series of ownership changes, staff reductions, and other controversies. In January 2018, the paper's staff voted to unionize and fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electronics Companies Of The United States
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow. Electronics has hugely influenced the development of modern society. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018. The largest industry sector is e-commerce, which generated over $29 trillion in 2017. History and development Electronics has hugely influenced the development of modern society. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small elect ...
