1. An electronic unit for a level measurement probe for measuring a level of a medium, comprising:
at least one first excitation electronic unit configured to emit a first excitation signal; and
at least one second excitation electronic unit configured to emit a second excitation signal,
wherein the first excitation signal and the second excitation signal are different,
wherein the electronic unit is configured to emit the first excitation signal and the second excitation signal simultaneously to the level measurement probe, and
wherein the first excitation signal and the second excitation signal have different frequencies.
