Swept Long Line Detector Network Analyzer

A network analyzer is described which provides the measurement of both magnitude and phase of S/sub 11/ and S/sub 21/. The RF components of the system are resistors, video detectors, and long lines, giving wide bandwidth. The attenuation of a long line changes with frequency and would make data difficult to evaluate if only one long line were used. Therefore the sweeper output is split by a resistive power divider
