Claim 15:
16. A measurement method for characterizing a device under test, wherein the device under test is established as an RF-to-digital device comprising an analog input, or wherein the device under test is established as a digital-to-RF device comprising a digital input, comprising:
generating a digital instruction signal or an analog stimulus signal for the device under test by a signal source;
in the case of generating the analog stimulus signal by the signal source, forwarding the analog stimulus signal to the device under test by a directional element, generating a digital output signal based on the analog stimulus signal by the device under test, and forwarding the digital output signal to an analysis module;
in the case of generating the digital instruction signal by the signal source, forwarding the digital instruction signal to the device under test, generating an analog output signal based on the digital instruction signal by the device under test, and forwarding the analog output signal to the analysis module via the directional element; and
determining, by the analysis module, at least one characteristic parameter of the device under test based on the analog output signal of the device under test or the digital output signal of the device under test.
