Assigning a label to standards is optional. However, the label is displayed in many dialogs and can
help you identify a standard or distinguish different standards with similar parameters.
If Circuit Model is selected in the S-params From panel, then the controls in the central panel of the dialog
are enabled. The circuit diagram is adjusted to the selected standard type. The following parameters can
be set:
 Frequency range (Min. Freq. to Max. Freq) for which the circuit model is valid. During calibration,
the analyzer checks whether the sweep range is within the validity range of all measured
standards and possibly generates a warning (see Measure Standards dialog).
 Offset and Load parameters of the circuit model.
The impedance for waveguides is frequency-dependent. If a waveguide line type is selected in the
Offset Model dialog, the circuit model indicates varies instead of a definite impedance value.

Restrict Port Assignment
Opens a dialog to define whether the standard can be connected to any port of the analyzer or to just one
port (for one-port standards) or a pair of ports (for two-port standards).
The port assignment is displayed in the Add or View / Modify Calibration Kit dialogs.
Port assignment and gender
The standards are handled differently, depending on their port assignment:
 If the port assignment is not restricted, the gender belongs to the definition of polarized standards.
When the connector type and calibration kit is selected in the calibration wizard, the analyzer
checks whether the kit contains the necessary standard types and whether the standards have
the right gender.
 Standards with restricted port assignment are assumed to have the gender that is appropriate for
the calibrated port. In the View Modify Standard dialog, the Gender: input field is disabled. In the
calibration wizard, the analyzer checks whether the kit contains the necessary standard types for
the required ports. Instead of the gender, the port assignment is stored in the calibration kit file.
This approach simplifies the definition of standards and helps to avoid inconsistencies.
