Abstract:
1. A measuring device comprising a first transformation device, a first time-quantization device and a selection device, wherein the first transformation device implements a transformation of at least one signal into the frequency domain, wherein the first time-quantization device subdivides at least one signal into several signals disposed in time succession, wherein the selection device implements a selection of partial signals suitable for a measurement, and wherein the first transformation device and the first time-quantization device process a test signal in succession and generate from it frequency-time partial test signals, wherein the frequency-time partial test signals are excerpts of the test signal in the time domain and frequency domain, wherein the partial signals selected by the selection device are frequency-time partial test signals, and wherein the selection device determines frequency-time partial test signals suitable for a measurement by comparing their mean power with at least one upper threshold value, the frequency-time partial test signals being applied to a device under test, and the device under test adapted to generate an output signal based upon the test signals applied thereto.
