Open Discussion
Date:
Start time: 1:05 PMPST
End time: 2:00 PM PST
Location: B2 - Customer
Purpose: Provide an assembly which will accommodate the components included in the UltraFlex test head General Purpose Interface Option and maintain compatibility with corvette instrument module.

Design Objectives
This equipment is an option which is provided by Teradyne per customer request.
The designated area of the GPIO is test head slot #25 in the (slave support board slot). This location remains consistent whether the test head is 26 slot or 36 slot configurations.
The GPIO is restricted to slot 25 only, sidewalk #1 and sidewalk #2 only. This proposed concept of GPIO will focus on these JIB locations.
Provide access for cabling which comes from the GPIO convenience panel (outside the tester) to the GPIO JIB assy and DIB.
This option must be compatible to the Corvette JIB mechanics on the slave support board.
A new spanner bracket design specific to Corvette.
