1. Introduction to New Final Device Test System DSA 6000
Johnny Hansen
January - August 2009

2. Different FDTS scenarios
New FDTS – backwards compatible with C3 models
Direct replacement of AUDIOmaster system
Pro - Works for both C3 and C4 devices + wireless
Con- Not all C3 devices migrated at introduction
New FDTS – not backwards compatible
Works only for C4 and going forward
AUDIOmaster still needed for C3 devices
Pro – Only one TPI pr. device model
Con - Difficult to balance in production
Mixed solution – AM TPI’s for C4 (wireless) + New FDTS
AM update for Windows XP (due to Ratatosk)
AM development of hardware upgrade for wireless
Development of Test programs for New FDTS
Pro - Implementation not tied to MARS introduction
Pro – Expenses not tied to MARS
Con - Extra (not double) work for EA groups.
Con - Slow implementation of new FDTS

15. Software

16. Three technologies introduced in .Net 3.0
Software configuration
PC operative system : Windows XP
Test software core is NI TestStand & AUDIOmaster
Test stand sequences is a standard NI product
Test library is AUDIOmaster from MicroLEX
NI acquired Microlex in 2008
One supplier for all purchased SW
GN still develop test programs
Three technologies introduced in .Net 3.0
WPF – Windows Presentation Foundation
WF – Windows Workflow Foundation
WCF – Windows Communication Foundation 16

17. Current execution components

18. Workflow execution components (WF)

19. Remote configuration (WCF+WF)

20. Publish based TPI deployment (WCF+WF)

21. Top 3 benefits from new hardware.
Standard components from a high quality supplier
All modules very easy to replace during repair.
Industrial PC designed to run
System can test both Coyote 4 and Coyote 3 products
Top 3 benefits from new software.
Easier updating of new TPI’s
Automated loading of TPI’s possible
Batch loading of TPI’s (whole family at one time)
Easier development and maintenance for R&D groups.
