Foldback Input Voltage The Foldback Input Voltage shown in this screen is a DC voltage which is
proportional to the reflected power returning to the transmitter output (the
transmitter VSWR). Excessive reflected power coming back to the transmitter will
cause the exciter RF output power to reduce. This is referred to as VSWR
foldback.
