Signal generating device and measurement device

A signal generating device for generating measurement signals for an electrical system, the signal generating device comprising:

• a housing comprising an electrically conducting material;
• an energy reservoir arranged in the housing;
• a data interface arranged at the housing and configured to receive signal data;
• a coupling interface arranged at the housing and coupled to the electrical system;
• a signal generator arranged in the housing and coupled to the electrical energy reservoir, the data interface, and the coupling interface, wherein the signal generator is configured, based on the signal data, to generate the plurality of measurement signals and to output the plurality of measurement signals via the coupling interface;
• and
• a plurality of load simulators arranged in the housing, wherein the plurality of load simulators are arranged electrically between the coupling interface and the signal generator;
• wherein an input side of the plurality of load simulators comprises a first input line and a second input line,
• wherein the first input line is coupled to the signal generator,
• wherein the second input line comprises a terminating resistor, and
• wherein the plurality of load simulators comprise an input switch configured to switch to the first input line or to the second input line respectively.
