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