Figure 2-13 VSWR Measurement Interface
Measurerment Results: return loss, reflection coefficient and VSWR.
This measurement requires the VSWR, VSWR bridge and TG options. Two
measurements have to be performed according to the measurement wizard at the
lower side of the interface: measurement with the device under test disconnected
(represented by trace 2) and measurement with the device under test connected
(represented by trace 1). The return loss (represented by the math trace) is
determined by the difference of the results of the two measurements and the
reflection coefficient and VSWR are determined by the return loss.
