Patent number: 10884045Abstract: Device and method for analyzing a probe, in particular for analyzing a symmetrical, differential probe. A ground-based test signal is provided to a main signal line, wherein the main signal line is terminated by a predetermined impedance. Furthermore, at least one additional signal line is provided, wherein a further impedance is arranged between the additional signal line and the ground. Accordingly, a differential probe may measure a differential signal between the main signal line and the additional signal line. Hence, no grounded signal is provided to the probe.
