Abstract:
1. A device for measuring electrical variables, the device comprising: an external measuring connection that is connectable to an electronic device to be tested; at least one converter configured to convert a plurality of measurement variables, measurable or measured via the measuring connection, of different variable types into respective electrical measurement variables of a single predefined or predefinable variable type; and a control device configured to control the converter and to select at least one variable type of the plurality of measurement variables that the converter will convert to the single predefined or predefinable variable type; wherein the converter includes an independent input stage for each of at least two measurement variables of different variable types, each input stage configured to detect a different respective measurement variable of the at least two measurement variables and to convert the respective measurement variable into a predefined or predefinable variable type, the converted measurement variable of the predefined or predefinable variable type being provided at a signal output of the input stage, and wherein an electrical signal provided at the measuring connection is analyzed in parallel at the at least two input stages for different variable types, such that the at least two input stages are operated parallel in time and provide their respective converted measurement variable of the same predefined or predefinable variable type substantially simultaneously at respective signal outputs of the input stages.
