How to Build a Fixture for In-circuit Test (ICT)
应用文章
Cover-Extend Technology (CET) is Keysight’s latest limited access solution for in-circuit test (ICT). The Keysight Technologies, Inc. Medalist VTEP v2.0 Powered suite now consists of Cover-Extend Technology, VTEP, iVTEP and Network Parameter Measurement (NPM). For Cover-Extend Technology implementation, additional hardware and changes to the fixture are required. This paper documents the necessary information for a fixture vendor to build a Cover-Extend fixture. All previous best practices in building a standard ICT fixture still applies.
Hardware Requirement
To build a Cover-Extend fixture, Cover-Extend Ready (CE Ready) VTEP mux card and Cover-Extend signal condition card (CET card) are needed. The normal VTEP Mux card WILL NOT work for Cover-Extend. Only the Cover-Extend Ready VTEP mux card identified with the VTEP v2.0 Powered! Ready label (on the flex cable connector located in the middle of the Mux Card) will work for Cover-Extend.
