Parameter
Meaning
Comment/Unit
'<CalKitLabel>'
Label (e.g. the serial number) of the calibration kit; for
...WLABel
com-
mand only
String parameter
'<StandardLa-
bel>'
Label (e.g. the serial number) of the standard
String parameter
<MinFreq>,
<MaxFreq>
Min./max. frequency for which the circuit model is valid
Default unit is Hz
<DelayParam>
Depending on the cal kit's model type (selected using
is interpreted as:
●
delay [s] for Keysight modeling
●
el. length [m] for ZVR compatible modeling
Cal kits that are not created/modified using
[SENSe:]CORRection:CKIT:DMODe
use the ZVR compatible
modeling.
<Loss>
Loss (offset parameter) of the standard
Must be specified without unit
(implicit unit is dB)
<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 <C
i
> 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 <L
i
> 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.
Character data | numeric value
<Port1>,
<Port2>
Optional port restriction: one port number for one-port standards, two port
numbers for two-port standards
Integer values
The different standard types are defined by the following parameters. Port restrictions
are indicated in brackets:
