Reflection Coefficient: the ratio of the reflected voltage to the incident
voltage.
VSWR: the ratio of the maximum voltage to the minimum voltage of the
standing wave.
This measurement requires the VSWR, VSWR bridge options and TG
(DSA832E-TG). Two measurements have to be performed according to the
