A novel method of multifrequency signal measurement with measuring line

A novel measurement approach combined with measuring line is proposed and investigated to complete the work of multifrequency signal measurement. Namely, the signal is measured by using microwave measuring line based on space Fourier transformation (SFT) method. In addition, good result is obtained through the method, when simulation is taken in LabVIEW and automatic measuring line system is used in experiment test. Using measuring line with the method not only can complete measurement of various microwave parameters, but also can measure the frequencies of multifrequency signal. The method for multifrequency signal measurement in this paper is practical to design low cost and multifunction microwave measurement system.
