The work concerned about the designing, realisation, characterisation and validation of new functionalities of the DXPE201 board, a pin electronic created in SPEA s.p.a.. This Pin Electronics (PE) is used into an Automatic Test Equipment (ATE) with the asylum of a Device Interface Board (DIB or also called load-board) in order to test the boards' circuitry and the functionalities of the semiconductor Device Under Test (DUT). The rule of DXPE201 is to deliver digital signals, power, or execute precise voltages and currents measurement of DUT's electrical characteristics. The measurement of the board have a certain error declared in the datasheet that must be validate with some good practise technique's.
