A second order linear system suited for analog instrumentation is presented. Shown are the corresponding phase portrait nodes, a root focus and a central point. The experimental prototype is of easy implementation and of low cost as it is comprised only of passive elements (i.e resistors, capacitors) and operational amplifiers.

Keywords : Phase portrait; analog electronic; ordinary differential equations.
