Signal routing software picks a path for T&M switch system development

August 16, 2016 // By Graham Prophet
Pickering Interfaces (Clacton-on-Sea, UK), provider of modular signal switching and simulation for electronic test and verification, has added a signal routing software product, Switch Path Manager.

This software simplifies signal routing through switching systems and speeds up the development of switching system software. It can be used in NPI labs as they develop test procedures as well as in automated test systems.

 

Originally known as Tecap Switching, Pickering is adding new features to the software and renaming it to better address the market requirements as well as clearly identifying the functionality. Switch Path Manager will become part of Pickering’s super installer, which will provide customers access for up to 90 days at no cost.

Switch Path Manager signal routing software speeds up switch system development by automatically connecting system endpoints. The software supports Pickering’s PXI, LXI, PCI and GPIB switching systems and the interconnection between them.

Within small switching system configurations, or when utilizing just single switch modules, the user typically applies device drivers with the provided API to control the relays. Simple CLOSE and OPEN commands are combined with additional parameters such as module number and channel number to control the required relays. As switching systems get more complex, this seemingly simple task can get quite complicated.

 

Switch Path Manager virtually describes any switching architecture and processes all stored project data for switching and routing at runtime. The user selects the modules from the library, and defines the physical interconnections, as well as the endpoints. Endpoints are the boundary of the system where measurement and stimuli equipment and all the UUT access points are connected. By calling Point-to-Point or Point-to-Multipoint functions the routing is processed and the required relays are controlled to establish a signal path between these endpoints. The router will never interfere with existing routes and will find an alternate bypass or will terminate with an error message if not successful. In addition, the router is intelligent enough to minimize the risk of unintended short circuits.
