A measurement system (10) for characterizing a device under test (12) is disclosed. The measurement system (10) comprises a signal source (14), an analysis module (16), and a directional element (18) that is connected to each of the device under test (12), the signal source (14), and the analysis module (16). The signal source (14) is configured to generate a digital instruction signal or an analog stimulus signal for the device under test (12). In the case of generating the analog stimulus signal, the directional element (18) is configured to forward the analog stimulus signal from the signal source (14) to the device under test (12), wherein the device under test (12) is configured to generate a digital output signal based on the analog stimulus signal received. In the case of generating the digital instruction signal by means of the signal source (14), the device under test (12) is configured to generate an analog output signal based on the digital instruction signal received, wherein the directional element (18) is configured to forward the analog output signal generated to the analysis module (16). The analysis module (16) is configured to determine at least one characteristic parameter of the device under test (12) based on the analog output signal of the device under test (12) or the digital output signal of the device under test (12). Moreover, a measurement method is disclosed.
