Definitions for "Voltage Standing Wave Ratio"
Keywords:  vswr, mismatch, impedance, ohm, minimum
VSWR - A measure of the uniformity of impedance along a transmission line, or the quality of the impedance match between a line and the source or load.
In a transmission line, the ratio of maximum to minimum voltage in a standing wave pattern.
In a waveguide, the ratio of the electric field (voltage) at a maximum point to that of an adjacent minimum point.
