Expansion Board FlexIO

Expansion Board FlexIO

The Expansion Board FlexIO extends the functions of the µLC Test System by adding six versatile channels that can handle various types of signals, including analog and digital. It enables manipulation of different signal types, such as PWM and SENT, and supports complex configurations for advanced testing scenarios.

With features like error simulation and flexible signal processing, the board is well-suited for automotive and engineering applications where precision and adaptability are essential.

To determine the slew rate, an upper (Uhigh) and a lower (Ulow) threshold voltage were defined. Subsequently, the maximum time span required for a switching process to transition from one voltage range to the other was determined. A load resistor (RL) value of 390 Ohm was selected.
