Abstract:
1. A test device for testing a radio device, comprising: an imaging device configured to image information to be transmitted onto various signals differing with regard to the carrier frequency; a noise-generating device configured for the addition of one frequency-dependent noise component to a signal of a carrier frequency, wherein a step function is a presentation of the frequency-dependent noise components per carrier frequency, and wherein a certain noise component corresponds to a certain carrier frequency, and this certain noise component is added to the certain corresponding carrier frequency; a transmission device configured to transmit the resulting noisy signals and non-noisy signals of the various carrier frequencies to the radio device; a receiving device configured to receive a response signal sent back by the radio device in response; and an analysis device configured to evaluate the response signal, wherein the analysis device comprises a comparison device configured to compare the qualitatively best carrier frequencies extracted from the response signal with anticipated, qualitatively best carrier frequencies, and wherein the anticipated, qualitatively best carrier frequencies are determined from the frequency-dependent noise components added to the carrier signals.
