GPIB vs VXI-Basic difference between GPIB and VXI interfaces
This page on GPIB vs VXI mentions basic difference between GPIB and VXI interfaces.The difference between various terms and other instrument interfaces are also mentioned.
GPIB interface
This interface is designed to interface computers, instruments and other peripherals. This enables GPIB interface to carry data as well as control information between them. One need GPIB adaptor to provide this connectivity. GPIB can used to interface about 14 devices. Data transfer speed of max. 200 Kbps can be achieved. The interface is suitable for lower distance need. Refer comparison factors between GPIB and Serial interface.
VXI interface
This interface is based on VMEbus architecture. Compare to GPIB, VXI interface has achieved reduction in size and increased level of integration. But as it is based on old PC architecture, it does not leverage benefits of modern PC technologies.
| Specifications | GPIB | VXI |
|---|---|---|
| Width of Bus in bits | 8 | 8/16/32 |
| Data throughput | 1 OR 8 Mbytes/second | Max. 160 Mbytes/second |
| Synchronization | Not required | defined in the specifications |
| Size | Large | Medium |
| Software framework | Not needed | VXI plug and play |
| Modularity | Not supported | Supported |
| EMI shield | Optional | Defined in the spec.(All the modules need to be enclosed in metal shield to meet the EMI requirements of EM radiation and susceptibility. |
| Cost of the system | Higher | Medium to High |
