Introduction: Testing of electronics for automotive applications calls for a special artificial network (or line impedance stabilisation network, LISN), which provides a normalized impedance on the power lines for measurement purposes. This networks are readiliy available but usually at pretty steep prices. This design is about a small low current artificial network for pre-complinace testing. Most devices that need to be tested don't require excessive currents (> 10A). This makes it possible to use of-the-shelf parts for the network instead of special custom parts.
