Vector network analyzer having multiplexed reflectometers for improved directivity

摘要: A vector network analyzer (VNA) in accordance with the present invention for measuring a frequency response of device under test (DUT) includes signal source, port, path connecting port and reflectometer receiver that when activated taps onto within primary range. The is adapted to be electrically connected DUT while disconnected from frequency-extension module or serially between DUT. When module, active so measureable range using source. series deactivated extension wider than substantially overlapping
