About VME, VPX and VXI Bus Interfaces and Adapters

VME, VPX and VXI bus interfaces and adapters allow VME, VPX and VXI buses to communicate with other types of computer systems and devices. The VersaModule Eurocard (VME) bus is a popular, 32-bit bus used in many industrial, commercial and military applications. VME extensions for instrumentation (VXI) are an electrical and mechanical standard used mainly with automatic test equipment (ATE). VXI allows equipment from different vendors to work together in a common control and packaging environment. VPX (a.k.a. VITA 46) is an ANSI standard based on the VMEbus with support for switched fabric using a high speed connector. VXI combines VMEbus specifications with features from the general-purpose interface bus (GPIB) to meet the needs of instrumentation applications. Other technologies for VME, VPX and VXI controllers and processors may also be available.

Selecting VME, VPX and VXI bus interfaces and adapters requires an analysis of available technologies. The original VME bus (VMEbus) uses Eurocards, rugged circuit boards that provide a 96-pin plug instead of an edge connector for durability. VME64 is an expanded version of the VMEbus that provides 64-bit data transfers and addressing. VME64 features include asynchronous data transfers, an addressing range between 16 and 40 bits, data path widths between 8 and 64 bits, and a bandwidth of 80 Mbps. VME64 extended (VME64x) is an improved version of the original VMEbus that features a 160-pin connector family, 3.3 V power supply pins, bandwidths up to 160 Mbps, injector/ejector locking handles, and hot swap capability. VME160 transfers data at 160 Mbps. VME320 transfers data at a rate of 320 Mbps. VXI combines VMEbus specifications with features from the general-purpose interface bus (GPIB) to meet the needs of instrumentation applications. VME, VPX and VXI bus interfaces and adapters for VPX applications are also available.

Products & Services Related to VME, VPX and VXI Bus Interfaces and Adapters

VME, VPX and VXI Controllers and Processors
VME, VPX and VXI controllers and processors manage data transfers between devices in VME, VPX, and VXI systems. They control the status of interrupts, interrupt requests (IRQ), registers, and triggers, as well as network instruments for testing and analysis.
VME, VPX and VXI Extenders
VME, VPX and VXI extenders are boards that are used to improve or extend the functionality of standard VME, VPX, and VXI cards.
VME, VPX and VXI Products
VME, VPX and VXI products are designed for use with a VME, VPX or VXI bus. They include controllers and processors, extenders, switches, bus interfaces and adapters, power interface boards (PBs), and load boards.
VME, VPX and VXI Switches
VME, VPX and VXI switches are used to connect test points or devices to instruments for testing, measuring, or monitoring. They provide a variety of switching and routing functions for test systems based upon the VME, VPX, and VXI standards.
