3 Terms and definitions
The following terms and definitions as defined in GB/T 11313.1 apply to this document.
3.1
Reflection coefficient reflectionfactor
The ratio of the magnitude of the reflected wave vector on any section of the connector to the magnitude of the incident wave vector is expressed by equation (1).

In the formula.
Γ --- reflection coefficient;
Vi --- incident voltage;
Vr --- reflected voltage;
Z0 --- the nominal impedance of the transmission line in ohms (Ω);
ZL --- Transmission line termination load impedance in ohms (Ω).
3.2
Voltage standing wave ratio voltagestandingwaveratio
The ratio of the maximum voltage to the minimum voltage on any section of the connector, its expression and the relationship with the reflection coefficient are expressed by equation (2).
VSWR=
Vmax
Vmin =
Vi Vr
Vi-Vr =
