Abstract
A system for making HF and DC measurements on a DUT includes a HF unit having a HF connection terminal that is switchable to a connected or disconnected state; a DC unit having a DC connection terminal that is switchable to a connected or disconnected state; and a common connection between the connection terminals adapted to be connected to the DUT. The DC connection terminal has a transmission line characteristic that is impedance-matched to minimize reflections when the HF connection terminal is in the connected state and the DC connection terminal is in the disconnected state.
