Abstract
A testing device for testing a distance sensor that operates using electromagnetic waves includes: a receiving element for receiving an electromagnetic free-space wave as a receive signal (S); and a radiating element for radiating an electromagnetic output signal (S). In a test mode, a test signal unit generates a test signal (S), and the radiating element is configured to radiate the test signal (S) or a test signal (S′) derived from the test signal (S) as the electromagnetic output signal (S). In the test mode, an analysis unit is configured to analyze the receive signal (S) or the derived receive signal (S′) in terms of its phase angle (Phi) and/or amplitude (A) and store a determined value of phase angle (Phi) and/or amplitude (A) synchronously with the radiation of the test signal (S) or of the derived test signal (S′) as the electromagnetic output signal (S).
