Fast power sources are required for the electrical testing of electrical and electronic components in motor vehicles in accordance with the **LV124 or VW80000** standard.
The classic 1-quadrant power supplies are generally not always the optimum solution here due to their rather slow signal processing. The fast HUBERT 4-quadrant power amplifiers are a versatile alternative for simulating a vehicle electrical system.


This application note presents some examples of tests from the LV124.
