Insertion loss
The insertion loss is a criterium for the effectivity of interference suppression components, as
measured by using a standardized measurement circuit
(fig.

Definition of insertion loss
The input terminals of the equipment under test are connected to an RF generator with impedance
Z (usually 50 ) . At the output end of the component, the voltage is measured using a selective
voltmeter having the same impedance Z . The insertion loss is then calculated from the quotient of
the no-load generator voltage V
and half the output voltage V
.
