Delivers Flexibility and High-performance

1000Base-T1 was initially developed for the automotive market, where the minimal weight of a single differential pair cable capable of high data rates was a requirement for modern automobiles. The standard has also been adopted for use in industrial control and building infrastructure Ethernet installations.

The compact single-slot 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 permit fault insertion on up to six channels of 2-wire connections, while the dual MUX 40-204 (PXI) and 42-204 (PXIe) provide fault insertion on one or two channels of 2-wire connections. Both models offer 100Ω controlled transmission line impedance signal paths.

The 40/42-203 range uses high-quality reed relays designed for high-frequency applications, while the 40/42-204 range 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 flexibility, with the 40/42-203 available with three channels and the 40/42-204 as a single channel. If the testing requirements increase, the fully populated modules double the channel count to six and two, respectively, in the same single chassis slot footprint. Both ranges use the MMCX connector interface, which permits a high channel count in a small panel area, although not differential.
