Parameter Meaning Comment/Unit
<Z0> Reference impedance (no unit) Must be specified without unit
(implicit unit is Ω)
<C0>,...,<C3> Polynomial coefficients for the fringing capacitance of the standard (load
parameter)
Must be specified without unit:
implicit unit of <Ci> is fF / (GHz)
i
<L0>,...,<L3> Polynomial coefficients for the residual inductance of the standard (load
parameter)
Must be specified without unit:
implicit unit of <Li> is pH / (GHz)

OPEN | SHORt |

<Resistance>
A load circuit model generally consists of a capacitance (modeled by
<C0>,...,<C3>), connected in parallel to an inductance (modeled by
<L0>,...,<L3>) and a resistance, both connected in series.
OPEN | SHORt | MATCh indicates a simplified modeling as an Open or
Short or Match standard.
●
OPEN: the resistance is infinite so that the standard behaves like a
capacitor (no inductance)
●
SHORt: the resistance is zero so that the standard behaves like an
inductance (no capacitance)
●
MATCh: the standard behaves like a match (no inductance, no
capacitance, resistance Z0)
<Resistance> indicates the general load circuit model.
