DATA ACQUISITION SYSTEMS SELECTION DATA ACQUISITION SYSTEMS Keithley Data Acquisition Systems combine precision measurement, switching, and control into a single, tightly integrated enclosure. They offer affordable alternatives to separate DMMs and switch systems, dataloggers/ recorders, plug-in card data acquisition equipment, and VXI/PXI systems.

Available at www.tek.com CHOOSING YOUR DATA ACQUISITION SYSTEM Designing the switching for an automated test system demands an understanding of the signals to be switched and the tests to be performed. The following is a quick look at basic key decision points in the design of a switching system. 1 Switch Coniguration Multiplex switching can be used to connect one instrument to multiple devices or multiple instruments to a single device. Multiplex switching permits multiple simultaneous connections and sequential or non-sequential switch closures. A matrix switch coniguration is the most versatile because it can connect multiple inputs to multiple outputs. The isolated, or independent, switch coniguration consists of individual relays, often with multiple poles, with no connections between relays. For scanner (or multiplex) cards, the channel is used as a switched input in measuring circuits or as a switched output in sourcing circuits. For switch cards, each channel’s signal paths are independent of other channels. 2 Relay Types Three key relay types are used. Electromechanical relays offer the widest power range and a good life and speed at a relatively low cost. Reed relays cost more but offer less contact wear and bounce for a better life and speed than electromechanical. Solid-state relays cost still more, but offer the best life and speed with no contact wear or bounce. 3 Systemization Connection types found on switch cards include both screw terminals and mass-terminated connectors. At the instrument level, TSP-Link master/slave connection offers easy system expansion between Series 3700A mainframes and Series 2600B SourceMeter instruments.
