ValidATE is the architectural implementation of the Valid Line for Level III (Board Test) applications. The system bay measures 60x96x182 cm and hosts 28 card cage slots using a VIP Test Backplane for a capacity up to 768 digital (or 384 full hybrids) high performance functional channels. Channel capacity can be doubled by adding a second VIP Backplane; a larger version of the system, hosting a 40 slot VIP Backplane(s) is also available. The system is offered with a standard choice of two types of receivers, the Seica traditional pin-bed and the ODU, which has a wide variety of extensions for ancillary connections of high frequency signals, coax, fiber-optics, pneumatic, etc. Custom receivers to accommodate specific requirements are also readily engineered. The system can be expanded to accommodate one or two additional bays for external instrumentation.
