MEASURING DEVICE, PARTICULARLY A VECTORIAL NETWORK ANALYZER WITH PHASE-SHIFT CONTROL

摘要

A method for operating a measuring device, particularly a vectorial network analyzer, which can be connected to an object to be measured via at least two gates, comprising a number of excitation units each assigned to a gate, each excitation unit having a signal generator with which the assigned gate can be subjected to the action of an excitation signal. The inventive method comprises the following steps: measuring the actual phase offset (Δφactual) between the excitation signals, which are output on the gates, at measuring points, and; changing the frequency of at least one of the two signal generators during a correction time interval (Tcorr) so that a predetermined set phase offset (Δφset) is obtained at reference points between the excitation signals output on the gates.
