Test LCD Backlight Inventers Using Modular Power System (MPS)
Application Notes
This application note describes how to use the Keysight Technologies, Inc. N6700 Modular Power System (MPS) to test the backlight inverter of a Liquid Crystal Display (LCD). Testing the inverters used to power and control the backlights of LCDs (coldcathode-fluorescent-lamp, or CCFL) requires multiple sequenced output voltages of different power ratings and precise timing with up to millisecond resolution or better. The N6700 MPS provides the flexibility and features needed in order to make the required tests and reduce costs by eliminating the need for multiple instruments and providing simple programming.
