In this paper, TPS Rehost method is proposed to expand the maintenance capability. We have obtained software and ITA (Interface Test Adapter) production drawings for this purpose. In consideration of the differences between the old ATE (Automatic Test Equipment) and the new ATE, The software procedure was reversed to GPIB(General Purpose Interface Bus) programming method and the ITA production drawing was redesigned to fit the field. The redesigned software and hardware were integrated through an integrated test and found voltage drop and inrush current problems during the process. The voltage drop generally varies according to the length and thickness of the wire. The problem is solved by compensating for the reduced voltage, which is a method that does not affect the configuration of the ATE. The inrush current problem is caused by the DC Signal Generator. Analyzed result shows caused by changing the operation mode, and solved the problem by operating only in one operation mode which operate without any inrush current.
