Bus Type to Analyze Computer bus system where the analyzer/exerciser will be used.


	Bus Type to Analyze:
	Your choices are...
	ISA / EISA		Industry standard architecture (ISA) buses can handle 16-bit data transfers at a clock speed of 8 MHz. They are also capable of handling memory under 16 MB. Extended ISA (EISA) is an enhanced version of the ISA bus. EISA buses run at 8 MHz, are capable of 32-bit data transfers, and can access all memory in the system.
	PCI / PCI-X		Peripheral component interconnect (PCI) is a local bus system designed for high-end computer systems. PCI buses transfer 32 or 64 bits of data at a clock speed of 33 MHz. They also support 3 to 5 critical peripherals, which are either integrated directly onto the motherboard or added via expansion cards. PCI buses fully support cards that were developed for standard I/O buses. PCI extended (PCI-X) is an enhanced PCI bus that is backward compatible with existing PCI cards and features speeds up to 1 Gbps. PCI-X was designed by IBM, Hewlett Packard (HP), and Compaq to increase the performance of high bandwidth devices such as Gigabit Ethernet, Fibre Channel, and clustered processors. Versions of PCI-X include PCI-X 66, PCI-X 133, PCI-X 266 and PCI-X 533.
	PMC		PMC is a form factor, not a bus. It is electrically equivalent to the PCI bus, but has a different shape and bus connectors. PMC is designed for rugged applications and provides a secure mounting platform for VME mezzanine boards.
	SCSI		Small computer systems interface (SCSI) is an intelligent I/O parallel peripheral bus with a standard, device-independent protocol that allows many peripheral devices to be connected to the SCSI port. A single SCSI bus can drive up to eight devices or units: the host adapter or controller, and seven other devices. Each device is assigned a different SCSI ID, ranging from 0 to 7. SCSI formats include SCSI-1, SCSI-2, SCSI-3, Wide SCSI, Fast SCSI, Wide Fast SCSI, Ultra SCSI, Ultra2 SCSI, Ultra3 SCI (Ultra160), Ultra 320 SCSI, and Ultra640 SCSI.
	CompactPCI / PXI		Compact PCI (cPCI) is a high-performance industrial bus that uses the electrical standards of the PCI bus and is packaged in a Eurocard. Specifications for the CompactPCI bus are developed and maintained by the PCI Industrial Computers Manufacturers Group (PICMG). cPCI buses are used extensively in systems that require high speed data transfers. Examples include data communication routers and switches, real-time machine control, real-time data acquisition, military systems, etc. PCI extensions for instrumentation (PXI) is a superset of CompactPCI that adds timing and triggering functions, imposes requirements for documenting environmental tests, and establishes a standard Windows^®-based software framework. Windows is a registered trademark of the Microsoft Corporation.
	VME / VXI		VersaModule Eurocard bus (VMEbus) is a popular, 32-bit bus used in industrial, commercial and military applications. The VMEbus is based on the VME standard, which defines mechanical specifications such as board dimensions, connector specifications and enclosure characteristics, as well as the electronic specifications for sub-bus structures, signal functions, timing, signal voltage levels, and master/slave configurations. The VMEbus uses 3U and 6U Eurocards, rugged circuit boards that provide a 96-pin plug instead of an edge connector for durability. Several VMEbus varieties are available. VME extensions for instrumentation (VXI) is 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.
	GPIB (IEEE 488, HPIB)		The general-purpose interface bus (GPIB) is designed to connect computers, peripherals and laboratory instruments so that data and control information can pass between them. It was originally developed by Hewlett Packard (HP) and called the HPIB bus. GPIB is also know as the IEEE 488 bus, and is electrically equivalent to the IEC 625 bus.
	USB		Universal serial bus (USB) is a 4-wire, 12-Mbps serial bus for low-to-medium speed peripheral device connections to personal computers (PC), including keyboards, mice, modems, printers, joysticks, audio functions, monitor controls, etc. The USB design is standardized by the USB Implementers Forum (USBIF), an organization that includes leading companies from the computer and electronics industries. The current USB specification is USB 2.0, which supports data transfer rates of up to 480 Mbps.
	IEEE 1394 (FireWire^®)		IEEE 1394 or FireWire® is an interface standard adopted by the Institute of Electrical and Electronics Engineers (IEEE) for very fast digital data transfers such as streaming video. IEEE 1394 connectors are used to transmit and receive data among FireWire devices, and are designed to replace external high-speed peripheral connections to personal computers, including hard disks, CD-ROMs, DVDs, graphics cards, high-speed scanners, direct video, monitors, etc. Tiny, robust FireWire connectors will also become important parts of home entertainment, communication, and appliance networks. FireWire is a registered trademark of Apple Computer, Inc.
