The Mechanical Length dialog contains the three editable columns Mech. Length, Permittivity (
r
) and
Velocity Fact. The velocity factor is 1/sqrt(
r
) and is a measure for the velocity of light in a dielectric with
permittivity
r
relative to the velocity of light in the vacuum (velocity factor < 1); see Offset parameters:
Definition above. Permittivity and velocity factor overwrite each other.
Click Same Dielectric at Each Port to change the permittivity or velocity factor for all port by
entering a single value.

Delay
Opens a dialog to define the offset parameters for the different physical and logical test ports as delays.
The delay is calculated as the product of the mechanical length and the square root of the
permittivity
r
divided by the velocity of light in the vacuum; see Offset parameters: Definition above.
Open the Mechanical Length dialog to change the permittivity.
