5.5.2. Return loss:
Return loss measure the amount of energy that is lost due to reflection which resulted
from impedance mismatching at the interface. Return loss is essentially defined as the
ratio of the power incident upon a given transmission system to the power reflected
caused by impedance mismatch with respect to reference impedance at
the interface
between source and device. Return loss figure are a function of the impedance of the
circuit involved and are therefore frequency dependent. These impedance must be
closely maintained in order to reduce the possibility of undesirable reflection and echoes
which in long distance circuit the telephone user or destroy the data being sent. To
perform the return loss test, open, short, load calibration must be done prior
measurement while the LCR impedance analyzer being selected in impedance mode.
Return loss is general expressed in decibels. General return loss equation is as follows.
Return loss = 20 log
