Yelo PXI Test Instrumentation

General Purpose Functional Tester
The Yelo Pixi general-purpose tester is a PXI based functional test system with in-circuit and continuity capability. Built into a free-standing 19” rack is a PXI chassis, mass interconnect fixture interface, PC, flat screen, and space for additional user-selectable instrumentation.

Software Features
The Yelo Test Executive software provides a standard user interface and test sequencer and includes a wide range of reporting options. The high-level functional test program imports user parameters to allow tests to be developed without the need to write any software code. Also included are standard continuity and in-circuit test programs which are able to read in net lists and component lists from files and test directly against these.

The standard test functions or VI’s that automatically resolve the switching routes from the instruments to specific pins on the fixture interface. These VI’s will allow the user to specify pin numbers on the fixture as part of a DMM or other instrument measurement call. This includes VI’s to provide continuity and in-circuit measurements.

Hardware Features
* The system is housed in a 37U 19” rack with a fixture interface mounted at desk height complete with shelf for supporting the fixture Rackmount PC with MXI interface.
* The system uses a PXI chassis and a number of high-density matrix cards combined with an LCR card to create an analogue in-circuit capability. A guarding card is also fitted to provide guard capability.
* Functional test uses PXI instruments and multiplexes these through the relay matrix used for the in-circuit capability. Power supplies are rack-mounted and hard-wired to their own connector on the fixture interface.
* 9U of uncommitted space for user-selected instruments.
* LCD & keyboard mounted on side arm for operator ergonomics. Mains distribution unit (MDU) and emergency stop button provide built-in safety features.
