ValidATE Plus is electrically the same as  the ValidATE System. The ergonomics  are changed to best suit the requirements of combined in-circuit and functional test, when a bed-of-nails fixture is more appropriate. Together with the ability to thoroughly verify the functionality of digital, analog and mixed-mode circuitry, the ValidATE Plus can extend its application to power-off, structural and power-on in-circuit techniques. The system combines best-in class solutions for board testing to meet performance, capacity and fault location capabilities. The system takes advantage of all techniques to reduce test generation cost, without affecting fault coverage or throughput. Power-off structural tests, using both junction and capacitive techniques, are first used to isolate simple manufacturing faults. Power-on in-circuit tests, both analog and digital, including extensions to IEEE 1149 techniques, are then deployed through the non-multiplexed hybrid channels of the system. Where required, fast On Board Programming (OBP) operations can be performed. Finally, the full power of functional test can certify operation of the UUT.
The ValidATE Plus base configuration is a single horizontal bay that accommodates the system’s power distribution, UUT power supplies and the test backplane to host various types of channel cards and instrumentation. The ValidATE Plus is an ideal ergonomic solution to be used with bed-of-nails fixtures, offering the operator full access control to the UUT, control panel, oscilloscope and system’s PC, as well as a comfortable area for documentation, schematic and tools. The system can be expanded to accommodate one or two additional bays for external instrumentation. Standard or custom fixtures are pneumatically (or alternatively vacuum) engaged into a robust, high performance receiver, granting access through the signal bus of the test backplane to all resources of the system.
