An electron microscope is disclosed which has a laser-driven photocathode and an arbitrary waveform generator laser system. The transmission method includes generating a codeword of a predetermined size Nencoded by encoding information data of a size Ninfo, and transmitting the codeword to a receiver. The signal processing component includes a second ground wire galvanically separated from the first ground wire on the chip and is connected to a second terminal of the component by way of a capacitor, in order to conduct interference signals as a result of electromagnetic couplings. The system further includes a user interface for interacting with the visualization.
