Terminating impedances which operate without reflections up to very high frequencies and are at the same time suitable for high voltages are required for EMP simulators. Instead of the previously normal copper-sulphate or ceramic resistors, which have various disadvantages, according to the invention, an axially symmetrical arrangement is used which is accommodated in a metal tube and consists of a plurality of chains (which are connected in parallel with one another) of series resistors of identical magnitude. As a result of suitable geometrical dimensioning of the construction and suitable selection of the value of the series resistors, the required terminating impedance can be implemented in a wide frequency range and with a high dielectric strength.
