The modules feature a PXI or PXIe control interface, allowing for chassis selection flexibility.
The new 1000Base-T1 fault insertion modules are available with various channel counts and two fault bus connections. The 40-203 (PXI) and 42-203 (PXIe) units enable fault insertion on up to six 2-wire connection channels, while the 40-204 (PXI) and 42-204 (PXIe) dual MUXs provide fault insertion on one or two 2-wire connection channels. Both models offer 100Ω controlled transmission line impedance signal paths. The 40/42-203 series utilizes high-quality reed relays designed for high-frequency applications, while the 40/42-204 series is based on high-quality electromechanical relays, with both families offering a long service life.
For smaller test applications, both versions offer partially populated options for greater flexibility, with the 40/42-203 available with three channels and the 40/42-204 as a single channel. If testing requirements increase, fully populated modules double the number of channels to six and two, respectively, in the same chassis slot space. Both ranges utilize the MMCX connector interface, which allows for a high number of channels in a reduced panel area, although not differential.
Steve Edwards, product manager for switching at Pickering Interfaces, comments: “1000Base-T1 was initially developed for the automotive market, where minimizing the weight of a single differential-pair cable capable of high data rates was a requirement for modern cars. The standard has also been adopted for use in industrial control and building infrastructure Ethernet installations. Fault insertion allows the user to simulate cable breaks in one or both conductors per differential pair. Furthermore, the two fault bus connections allow for the application of power channels such as Ground or Battery and the injection of other signals or a short-circuit condition into the differential pair. The 40/42-204 module provides a new feature in Pickering’s fault insertion range with its ability to route the differential pair to/from an external piece of test equipment. Due to the variety of industries it targets, we believe these fault insertion products will have many applications in various ATE systems.”
There are multiple suppliers of connector systems designed for 1000Base-T1 applications, and the industry does not standardize on a specific series. For this reason, customers can advise on their preferred connector range, and Pickering's connector division, Pickering Connect, can manufacture custom adapters to convert from the module's front panel MMCX connectors to the required 1000Base-T1 connector interface, as well as standard accessories for the module's connectors. Fault insert modules are covered by Pickering's standard three-year warranty.
