Description
We present two test-station designs for testing the latest version of a switch-mode power supply for the front-end electronics of the ATLAS TileCal. The new test-station significantly improves fault detection and reliability. We further discuss the steps taken to test the new Tile-LVPS, using a custom-based software to perform tests and graphically display and record all performance metrics. The test-station verifies performance specifications laid out by TileCal and ensures protection against over-temperature, over-voltage and over-current. These test-stations will build upon the previous generation of testing-stations used in initial production of TileCal system and power next generation of upgraded LVPS hardware.
