ABSTRACT:
An arrangement to determine at least one electrical feature of an electrical device including a signal injection unit configured to inject first and second test signals into the electrical device, a signal conversion unit configured to measure electrical qualities in electrical circuits resulting from the test signals, and a processing device including at least two input channels configured to receive the measured electrical quantities and to determine the electrical feature based on the measured electrical quantities. The arrangement further may include a mixing unit configured to add the measurements of a first electrical quantity determined from the test signals and based thereon generate a first mixed signal, to add the measurements of a second electrical quantity from the test signals and based thereon generate a second mixed signal, and to supply the first and second mixed signals to first and second input channels.
