PCI Switching Systems

Pickering interfaces offers a variety of switching systems in PCI PCI Products. The control basis of these is very similar to PXI (which uses the PCI bus) but the mechanical format is different. PCI uses the familiar slots seen on desk top PC's. The availability of these slots on modern desk top machines is declining in favour of PCIe slots, however there is a large industry based around industrial PC's which continue to prefer the PCI format. For that reason Pickering interfaces offers some of their switching systems and resistance simulators in PCI format.

The most common reasons for choosing PCI in preference to PXI are:

  • Chassis costs are generally lower than PXI

  • There may be spare slots in the PC which can be used to avoid adding a different chassis type

  • Some products are available in PCI but not PXI

The principle reason for not offering all switching designs in PCI are:

  • Not enough commercial demand

  • Some switching systems may not be suited for inclusion on cards which might reside in a PC for EMC reasons

  • PCI slots may have less cooling, are cooling from an unexpected direction, than PXI

  • The chassis power supply is less well defined

For these reasons PCI solutions tend to concentrate on systems which are not high power and will have fewer compromises when included in a desk top PC or an industrial chassis.

Pickering Interfaces is always willing to consider PCI versions of PXI designs.
