Keithley Introduces Integrated Multimeter/Switching System With Industry-Best Price, Channel Count and Performance.Business Editors CLEVELAND--(BUSINESS WIRE)--March 20, 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 its new Model 2750 Multimeter/Switching System, with a combination of channel count, cost per channel, and system performance that surpasses all other single-box measurement and control systems. This latest addition to the Keithley Integra Series has new mainframe features and plug-in module options that provide precision measurement and control in a single, highly integrated enclosure for either rack mounting or benchtop use. The Model 2750 mainframe combines five expansion slots and a growing family of 9 plug-in modules with a 14-function, 6 1/2-digit DMM See multimeter. DMM - Digital Multimeter (with NIST (National Institute of Standards & Technology, Washington, DC, www.nist.gov) The standards-defining agency of the U.S. government, formerly the National Bureau of Standards. It is one of three agencies that fall under the Technology Administration (www.technology. traceable accuracy). This combination allows up to 200 channels of 2-pole (differential) switching and multichannel Using two or more paths for transmission or processing. It can refer to a variety of architectures including (1) multiple I/O channels between the CPU and peripheral devices, (2) multiple wires in a cable, (3) multiple "logical" channels within a single wire or fiber or (4) multiple analog/digital I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output . At a cost per channel as low as $33, the Model 2750 is an affordable, high-performance alternative to separate DMMs and switch systems, dataloggers/recorders, VXI (VME EXtensions for Instrumentation) A peripheral bus specialized for data acquisition and real time control systems. Introduced in 1987, VXI uses all Eurocard form factors and adds trigger lines, a local bus and other functions suited for measurement applications. / PXI (PCI EXtensions for Instrumentation) A peripheral bus specialized for data acquisition and real time control systems. Introduced in 1997, PXI uses the CompactPCI 3U and 6U form factors and adds trigger lines, a local bus and other functions suited for measurement systems, and plug-in card data acquisition equipment. Applications and Markets. The Model 2750 is designed for production and product development testing where high throughput, high channel count, and high accuracy are needed for a variety of electrical signals. It can be used by virtually any company producing or using electronic components or assemblies, and will be of particular interest to high-growth market segments, such as optoelectronics, communications, and semiconductors. It helps ensure the reliability of electronic devices, such as power supplies, resistors, sensors and connectors, by finding faulty units or by sorting devices according to according to prep. 1.

Along with the Model 2750 mainframe, Keithley introduced three new plug-in modules: the Model 7709 6x8 Matrix Switch module, Model 7707 Multiplexer-Digital I/O module, and the Model 7701 32-Channel Multiplexer module. A total of nine different analog and digital I/O modules can be used with the Model 2750 to create highly flexible and cost-effective test platforms. Technical Details. The hardware and software features of the Model 2750 simplify its set-up and use in a test system. For example, the D-shell connector (hardware) D-shell connector - One of the family of connectors: DA-15, DB-25, DC-37, DD-50, DE-9, and DEH-15 [VGA]. The "D" is the shape of the shell, the next letter determines connector size, and the number is the maximum pin count. kits save installation and maintenance costs by allowing fast, mass terminations to multiplexer modules with a ribbon cable A thin, flat, multiconductor cable that is widely used for internal peripheral connections in electronic systems. In a PC, a 34-wire ribbon connects the floppy drive (if present) to the motherboard. . LabVIEW(R), LabWINDOWS/CVI(R) and TestPoint(TM) drivers speed test application development. With its tightly integrated DMM and switch system, the Model 2750 allows scan rates of more than 200 channels/second (up to 2500 readings/second), thereby reducing test times and increasing productivity. Moreover, the flexibility of its features and functions allows the Model 2750 to serve a wide range of industries and applications, such as production testing of electronic components, subassemblies and systems; accelerated stress testing Determining the durability of a system by pushing it to its limits. Stress testing a network is performed by transmitting excessive numbers of packets or attempting to break in illegally. , including HALT/HASS, ESS, and burn-in; process monitoring and control; and precision low-ohms measurements. Because resistance testing is often required in electrically noisy production environments, the Model 2750 was designed for measurements from micro-ohms to megohms using the offset compensation method. By expanding the measurement ranges, the Model 2750 can address applications normally reserved for more expensive and complex micro-ohm meters. This makes the Model 2750 an ideal choice when performing mission-critical milli- or micro-ohm measurements on connectors, harnesses, airbag squibs, sensors, semiconductors, or other low-ohm devices. Also, a built-in 20 mV clamp protects sensitive DUTs from voltage breakdown during ohms measurements and enables "dry circuit" testing that prevents metal oxide breakdown on electrical contacts. Built-in signal conditioning Imagine feeding the output of a temperature sensor, which is in millivolts, to an Analog-to-digital converter to be processed. Is it possible for the Analog-to-Digital converter to process such a minute voltage amplitude? The answer is probably no. on the Model 2750 mainframe can handle inputs up to 1000V / 3A (300V / 1A with the plug-in modules). The five expansion slots and nine different input modules provide the flexibility to vary channel count from 20 to 400 (single-ended), apply a stimulus to devices under test (DUTs), route signals, control system components, and make measurements with 14 different DMM functions. Robust digital I/O on the input modules can be used for triggering the Model 2750, handshaking Signals transmitted back and forth over a communications network that establish a valid connection between two stations. 1. handshaking - Predetermined hardware or software activity designed to establish or maintain two machines or programs in synchronisation. with other automation equipment and providing alarm limit outputs. High performance features on the mainframe, such as per-channel programmable scan lists, a 110,000 point memory buffer, built-in signal conditioning, scaling, and several math functions, enable the user to optimize system throughput in many automated test applications. Communication with a PC can be through either a GPIB (General Purpose Interface Bus) An IEEE 488 standard parallel interface used for attaching sensors and programmable instruments to a computer. Using a 24-pin connector, up to 15 devices can be daisy chained together. HP's version is the HPIB. or RS-232 interface. Price and Availability. The Model 2750 and new plug-in modules will be available from stock in March. The list price for the Model 2750 mainframe is $2750.00 and new plug-in module prices start at $595.00.
