New Keithley SourceMeter Provides Highest Output Available for Next-Generation OPTO Component Testing.Business Editors & High Tech Writers CLEVELAND--(BUSINESS WIRE)--April 10, 2001 Keithley Instruments Keithley Instruments (NYSE: KEI) is a measurement and instrument company headquartered in Solon, Ohio. Keithley develops, manufactures, markets and sells highly accurate instruments and data acquisition products, as well as complete system solutions for high-volume production , Inc. (NYSE NYSE See: New York Stock Exchange :KEI), today announced the latest in the Keithley SourceMeter(R) family, the Model 2440. It supplies the highest current available in a precision source-measurement system and is rated for a continuous 50W, 5A output. This makes the Model 2440 ideal for testing the latest generation of high-power pump lasers A laser used as the pump for an optical amplifier or other laser. See EDFA and laser. used in optical amplifiers A device that boosts light signals in an optical fiber network. Unlike regenerators, which have to convert light to electricity in order to amplify it and then convert it back again to light, the optical amplifier amplifies the light signal itself.

Fiber Amplifiers for dense wavelength-division multiplexing In fibre-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes multiple optical carrier signals on a single optical fibre by using different wavelengths (colours) of laser light to carry different signals. (DWDM (Dense WDM) The term given to wavelength division multiplexing (WDM) when significantly more channels were being added. Since WDM is increasingly more "dense" all the time, both terms are used synonymously. See WDM. DWDM - wavelength division multiplexing ) fiberoptic communication systems). Applications and Markets. Although the Model 2440 was designed for laser testing in the fiberoptic communications industry communications industry, broadly defined, the business of conveying information. Although communication by means of symbols and gestures dates to the beginning of human history, the term generally refers to mass communications. , its versatile design and high current capability makes it useful in a wide variety of testing applications. A typical use would be production testing of electronic components and assemblies for quality assurance, or sorting by electrical characteristics. Application Background. The Model 2440 can make a significant contribution to the efforts of the fiberoptic communication industry to improve device characterization during production of high power pump lasers. These devices are essential elements in optical amplifiers that help reduce the industry's dependence on Optical-Electrical-Optical regenerators in DWDM systems. Moving to an all-optical system lowers capital equipment cost, improves system performance and increases reliability. These improvements should speed up proliferation proliferation /pro·lif·er·a·tion/ (pro-lif?er-a´shun) the reproduction or multiplication of similar forms, especially of cells.prolif´erativeprolif´erous pro·lif·er·a·tion n. of DWDM networks, thereby strengthening the Internet and telecommunication backbones, and increasing DWDM usage in local metropolitan systems. Technical Details. The Model 2440 can serve a wide range of test applications requiring a continuous 40W source at up to 40V, or 50W at 5A. It can also measure voltages with 1iV resolution, and currents with 100pA resolution. The half-rack size instrument is capable of 4-wire and 6-wire remote sense resistance measurements ranging from one micro-ohm to 200 megohms. In addition to DWDM system applications, the Model 2440 can be used for high-volume production testing of diodes, resistance networks, varistors, integrated circuits Integrated circuits Miniature electronic circuits produced within and upon a single semiconductor crystal, usually silicon. Integrated circuits range in complexity from simple logic circuits and amplifiers, about 1/20 in. (1. , and other electronic components. The Model 2440 is the latest in Keithley's SourceMeter Series, and incorporates all of the basic features of that series. In addition to its tightly integrated source and measurement functions, the Model 2440 has the following programmable features: -- A built-in comparator that performs pass/fail testing in 500iS -- Unique 6-wire ohms function to measure individual resistors connected in networks -- Memory buffer to store up to 5000 5 1/2-digit readings -- A source memory list for storing and automatically executing up to 100 instrument configurations, including custom sweeps, conditional branching and pass/fail limit testing -- Built-in, user-definable math functions to automatically compute derived parameters -- Digital I/O interface, providing a high-speed link to component handlers and parts binning equipment -- Trigger Link interface for seamless integration with Keithley Series 7000 switching systems -- Optional contact check function to verify fixture, connector and tester wire harness integrity. The Model 2440 combines a precision, highly stable DC readback power supply and a low-noise 5 1/2-digit DMM See multimeter. DMM - Digital Multimeter . Basic accuracy for voltage programming is +/-0.02% and for current programming is less than +/-0.10 %. Typical measurement accuracy is +/-0.015% on 40 V range and +/-0.1% on the 5A current range. A highly versatile instrument trigger architecture in the Model 2440 simplifies measurement synchronization (1) See synchronous and synchronous transmission. (2) Ensuring that two sets of data are always the same. See data synchronization. (3) Keeping time-of-day clocks in two devices set to the same time. See NTP. and avoids such issues associated with multiple instruments. Price and Availability. The Model 2440 is available immediately with a list price of $5,995. As with all Keithley SourceMeters, the Model 2440 can be ordered with the contact check option. For More Information.
