Interface blocks(SSB) are used to transmit signals reliably between the test device and test system in internal, external, and customer-specific interfaces. Signal, high current, radio frequency, fibre optic, pneumatic, mixed, HSD and special blocks are available in various different versions.
Signal transmission occurs between two interface blocks mounted oppposite each other which are designed for a working distance of 15.1 ±0.5 mm between their mounting surfaces. In each case, one interface block is loaded with spring-loaded test probes while the other has rigid contact terminals. Pneumatic, fibre optic cable, and HSD couplings are also available. This achieves a continually high level of contact quality and reliable signal transmission while ensuring a uniformly low level of contact resistance. The interface blocks have uniform outer dimensions.
