VXI Bus Card P3 connector

The P3 connector is the least used as it is only available on the large format D-sized cards. It basically provides additional expansion over that available on the P2 connector. In this it provides 24 more local bus lines as well as further ECL trigger lines. one more clock is also available on this connector […]

VXI Bus Card P2 Connector

The P2 connector is present on all card sizes except the A sized card which is the most basic. The P2 connector provides additional capabilities: it expands the data bus to the maximum size of 32 bits. This adds four additional power supply voltages to provide the wider selection for on-card or on-module requirements; it […]

VXI Backplane and Card Connectors

VXI Backplane and Card Connectors

The VXI interconnection system has a number of requirements placed upon it. Some of the key requirements are that the connectors must be reliable, easily available and standardized; they must have the high pin count and be suitable for use in a rack system like VXI where backplanes and modules or cards are used. The […]

VXI Bus Card P1 Connector

The P1 connector is the only mandatory connector on the system. It carries the data transfer bus with up to 24 bits addressing, 16 bits of data, the interrupt bus and some power connections. VXIBUS P1 PIN DEFINITIONS & CONNECTIONS SLOT 0 – 12 PIN NUMBER ROW A ROW B ROW C 1 D00 BBSY […]

VXI Technology Advantages

Each the test technology has its own advantages. The need for the VXI Technology arose out of the need for the more compact and integration format for test solutions but in addition to this there are a number of other advantages that VXI brings to any solution: Compact test solution by the fact that all […]

VXI Bus System Configuration

VXI Bus System Configuration

The basic building block of the VXI system is the mainframe or chassis. This contains 13 slots into which various modules or instruments can be added. The mainframe as well contains all the power supply requirements for the rack and the instruments it contains. VXI employs the standard VME bus structure although further functions are […]

VXI Bus Cards Connectors

VXI Cards can have up to three module connectors. The actual number depends upon the size of the card. They are given the designations P1, P2 and P3. A sized card only possess the P1 connector whereas B and C sized cards have P1 and P2 and the D sized cards posses all the connectors. […]

VXI Bus Connector Pin-Outs

The VXI Bus carries three connectors designated P1, P2 and P3. From these VXI connectors only one connector is mandatory the P1 connector. The remaining two VXI Bus connectors P2 and P3 ones are the optional and are found on larger sized cards where more the interconnectivity is required. The connections to all three connectors […]

VXI Chassis System Configuration

The Module positions or slots are designated 0 to 12, slot 0 being on the left. The controller card, required in each solution, fits in slot 0. As a result the back plane for this slot is slightly modified to support the all requirements for the controller card. The controller is responsible for the performing […]

VXI Chassis Mechanical Configuration

The VXI chassis is one of the main elements of any VXI system. It provides the framework in which all the modules and cards can be held as well as providing the related interconnectivity along the backplane. The VXI chassis has been standardized, although there are number of options that can be selected. The specification […]

VXI Technology Development

The VXI standard was developed by VXI Consortium. This was formed in the year 1987 with the aim of defining the multi manufacturer standard that would enable test solutions to be more compact by having instruments contained on cards. The VXI Consortium originally consisted of GenRad, Hewlett Packard, National Instruments, Racal Instruments and Tektronix, but […]

What is VXI Technology?

Information about the basics of VXI Technology and the VXI Bus, VXI Bus, used as a standard for the test equipment in the production, repair and maintenance engineering / industries. VXI or VXI Bus is the powerful test instrumentation technology which is based on the VME bus. In fact the letters VXI stand for “VME […]
