What is vxibus

The VXIbus is established. The VXIbus is time tested, providing systems designers with security in the knowledge that their test platform will outlive the device being tested.

The VXIbus is thriving and has proven that it has the flexibility to evolve with the development of new technologies. Forgot Password. Sign In Register. This contains 13 slots into which various modules instruments can be added. The mainframe also 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 allocated to the uncommitted backplane pins.

This allows for functions that are required by test instrumentation to be implemented quickly and easily without the need for external connections. Functions that fall into this category include chassis wide clocks, timing and additional control. The VXI standard also imposes a variety of requirements on the module.

These are both electrical and mechanical. There are many electrical requirements. These range obviously from the way in which the module communicates across the bus to elements such as the fact that each module is required to perform a self test on power up. Any number of bus Masters may reside on the VME bus, but only one may have control of the bus at any one time.

The bus Master continues to control the Data bus during either interface. The Interrupts are acknowledged by the bus Controller. Revision C allowed 64 bit Data transfers, with the upper 32 data bits being multiplexed onto the address bus after the address was broadcast.

VITA 1. There are a number of other specification which increase the data through-put even higher by using the "user defined" P2 pins, the P0 connector or by bringing the data out the front panel. P 2 CI also uses the user defined P2 pins. There are a number of others. Refer to P2 Add-On Buses on the web for additional buses.

The original VME specification allowed for a 32 bit address bus and a data bus, which produced a maximum transfer rate of 40 MBps. Revision C provided another 32 bits of data to be multiplexed onto the address bus, once the address cycle was complete, during block transfers.

The VXIbus provides a time-tested bus you can trust to support your automated test and measurement needs. You can trust the VXIbus because it is well conceived, established, and time tested. More importantly, the VXIbus continues to thrive and is ideal for both current and future application requirements. Well conceived The VXIbus was well conceived by leading test and measurement companies to solve the most demanding test applications.
