OPEN | SHORt |
MATCh
Simplified modelling as an open or short or match standard. The load
circuit model generally consists of capacitance C which is connected in
parallel to an inductance L and a resistance R, both connected in series.
OPEN means that R is infinite so that the standard behaves like a
capacitor (no inductance, the polynomial coefficients specify C). SHORt
means that R is zero so that the standard behaves like an inductance (no
capacitance, the polynomial coefficients specify L). MATCh means that
the standard behaves like a match with the specified <Resistance>
Character data
<Resistance>
