Pickering Interfaces announces Switch Path Manager signal routing software

August 16, 2016 – Pickering Interfaces, a provider of modular signal switching and simulation for electronic test and verification, announced their 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 features to the software and renaming it to better address the market requirements as well as clearly identifying the functionality.

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. CLOSE and OPEN commands with additional parameters like module number and channel number control the required relays. As switching systems get more complex, this task can get quite complicated.

The user must always take care in order to avoid shorts or malfunctions even when performing simple switching tasks. If there are many relays involved, the risk of error increases significantly. Add to this the potential complexity of test code for the overall test program, and developing and debugging of the switching portion can be lengthy and prone to error.

Switch Path Manager 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.
