Overview
Modern ATE systems normally use multiple different instruments and switching matrices as well as flexible DUT interfaces. Signal connections between DUT and instruments are ofetn carried out by using external wiring.
The PXI platform offers many advantages as a base for test systems. Among them are a fast computer bus ( PCI, respectively PCI express), synchronization and trigger distribution, defined cooling as well as a rugged housing in 3U form factor. With more than 1200 products available from more than 70 vendors, PXI is a solid base for building test solutions.
An essential technology was not covered by the existing PXI standard and requires individual solution concepts: A bus system for distribution of stimulation and measurement signals accross the entire system, without external cables.
The AnalogBusExtension for PXI - ABex is an open system extension for PXI, which adds an analog bus and a power bus to the PXI system. Advantages lie in a more compact system architecture, improved signal quality due to less cabeling as well as in dramatic decrease of engineering hours during system integration.
