i1000D Diagnostic Test Set

Overview

Boundary scan test is widely used in current production line test, to perform connectivity test, device programming, or disabling routine to protect devices under certain functional tests.

The Keysight Technologies, Inc. i1000D in-circuit test (ICT) system is designed to serve general ICT purpose with cost-effective press-down type fixtures without compromising the quality of test. The newly designed graphical user interface helps engineers to perform their routine tasks efficiently. The ease of use also means a shortening of the programming and debug time for mass production line test implementation.

To meet the challenges and requirements of having a flexible test strategy for implementation at both the ICT and functional test stations, Keysight now provides a diagnostic application based on the i1000D ICT system - a desktop solution that allows easy and flexible deployment. The i1000D diagnostics test set (DTS) uses the same hardware engine as the i1000D system in a stand-alone form factor, which can be easily used for off-line R&D validation or serve as an independent programming station for diagnostic functional tests.

The basic configuration of the DTS provides 64 independent digital drivers and receivers. Each channel can be assigned for different purpose. With the innovative anti-interference cabling design, the U9401B-D01 hardware supports superior test signal integrity, which ensures the stability of tests in long wiring environments.

Boundary Scan

The i1000D DTS can easily perform boundary scan tests via the pre-defined test option interface. The user can easily assign a test access port (TAP) to 4 to 5 channels, together with upstream device disabling requirement. After loading a correct boundary scan description language (BSDL) file, the boundary scan test program can be generated by simply selecting the test item in the boundary scan GUI. Boundary integrity test, connect test, interconnect test, Device High Z, and Keysight’s latest Cover-Extend Technology (CET) are now available in the boundary scan test pre-defined category.

BSDL Reader

With the easy-to-read BSDL interface, the test engineer can easily understand the content of the BSDL, and define which pin to be tested or removed from test list.

The i1000D DTS now supports the latest extest-toggle instruction, which is a customized boundary scan command for vectorless test without bed of nails.
