Link With Scattering Parameters
In case the two measurement ports use the same reference impedance, the insertion loss is defined as:
and not, as often mistakenly thought, by:
- dB.
It is the extra loss produced by the introduction of the DUT between the 2 reference planes of the measurement. Notice that the extra loss can be introduced by intrinsic loss in the DUT and/or mismatch. In case of extra loss the insertion loss is defined to be positive.
For more detail, see the main article on Scattering Parameters.

Famous quotes containing the words link with, link, scattering and/or parameters:
“Because this age and the next age
Engender in the ditch,
No man can know a happy man
From any passing wretch,
If Folly link with Elegance
No man knows which is which....”
—William Butler Yeats (1865–1939)
“The lifelong process of caregiving, is the ultimate link between caregivers of all ages. You and I are not just in a phase we will outgrow. This is life—birth, death, and everything in between.... The care continuum is the cycle of life turning full circle in each of our lives. And what we learn when we spoon-feed our babies will echo in our ears as we feed our parents. The point is not to be done. The point is to be ready to do again.”
—Paula C. Lowe (20th century)
“A committee is organic rather than mechanical in its nature: it is not a structure but a plant. It takes root and grows, it flowers, wilts, and dies, scattering the seed from which other committees will bloom in their turn.”
—C. Northcote Parkinson (1909–1993)
“What our children have to fear is not the cars on the highways of tomorrow but our own pleasure in calculating the most elegant parameters of their deaths.”
—J.G. (James Graham)
