1. A radar level gauge system comprising:
a communication module configured to be connected to an external communication device;
a measurement module configured to generate, transmit and receive a measurement signal;
a control connection configured to connect the communication module to the measurement module, the control connection being configured to be in a high-impedance mode at least during a measurement by the measurement module;
a power supply configured to provide power to the measurement module;
an energy storage coupled to the power supply;
a measurement connection connecting the communication module to the energy storage, wherein the energy storage is arranged to be charged by the measurement connection and configured to provide power to the power supply for performing a measurement by the measurement module; and
a switch arranged between the communication module and the energy storage, the switch being controllable to break the measurement connection between the communication module and the energy storage during a measurement by the measurement module.
