Abstract: A method of characterizing an electric circuit of an electric device, a system, an electric device and a test device are provided. The system includes: a signal generator for generating a test signal having a radio frequency band spanning at least a portion of a frequency response range of the electric circuit; a load modulator for modulating the load with the test signal, thus generating a response signal in the electric circuit; and a correlator for generating cross-correlation between the response signal and the test signal.

Abstract: A system, apparatuses, a method, and a computer program for producing signals for testing radio frequency communication devices are provided. The system comprises a non-real-time domain which includes a data generator for supplying a temporally discontinuous data stream which data stream includes signal waveform data and control data defining characteristics of a conversion from the signal waveform data into a radio frequency test signal. The temporally discontinuous data stream is fed into a transformer which transforms the temporally discontinuous data stream into a temporally continuous data stream, thus providing a transformation between the non-real-time domain and a real-time domain. The real-time domain includes a radio frequency unit which uses the temporally continuous signal data stream as input, and performs the conversion from the signal waveform data into the radio frequency test signal according to the control data.

Abstract: An RF testing method and arrangement of an electronic device utilize sensors for measuring the electronic device under test in conjunction with production of the electronic devices. A comparator performs a comparison between measurement signals and corresponding reference signals from a reference supply and a decision unit determines defectiveness of the electronic device based on the comparison.
