It is often necessary to join two or more PXI buses, or a PXI and a PCI bus together in order to control more than one chassis concurrently. This can be accomplished by the use of a PXI bus expander that introduces a PCI to PCI bridge between the two adjoining systems (either PC to Chassis, Laptop to Chassis, or Chassis to Chassis). Several vendors offer solutions with a diverse set of configurations. This article will list the devices that Marvin Test Solutions offers, along with their respective configurations.
When choosing the PXI Bus Expander that is right for your application, make note of the configuration type and the bus types that will be bridged.
The following is a list of possible configurations and solutions that Marvin Test Solutions offers:
