The Diagnosys S500 system provides rapid functional test and fault finding for LRUs, PCBs and electronic assemblies through turnkey test solutions.

LRUs (Line Replaceable Units) and electronic modules or assemblies need to be tested against a set of predetermined test conditions to make sure they work as expected. This functional testing is designed to:

  • Rapidly test the LRU so that working units can be quickly identified and returned to operation.

  • Quickly identify faulty LRUs and start the fault-finding process by locating the most likely area of the failure to a lower level PCB or CCA or assembly. Having identified the suspect PCB or group of components (ambiguity group) a deeper level of diagnostic testing can be performed either using guided probing or through a separate fault identification system such as the PinPoint

Functional LRU testing is focused around the S500 system, which is a configurable and flexible test platform. Using industry standards where ever possible to provide cost effective capability, the Diagnosys know-how and expertise is applied to achieve specialized in-depth testing demanded by many industry sectors.

A user-friendly graphical user interface (GUI) is used across the S500 range of scalable systems. Complemented by training and tailored support packages, S500 functional test solutions enable you to benefit from rapid learning curves and extended through life capability.

In-depth diagnostic fault finding can be performed using:

1 The in-built functional guided probe capability of the S500

2 A separate in-circuit diagnostic test platform such as the PinPoint Range

3 A PinPoint Diagnostic Sub-System having an integrated flexible in-circuit diagnostic toolset and TestVue diagnostic software.
