To perform a system error correction, the physical port must be available as a source and
receive port. This condition is met if it is selected as a measured port in the Balanced and
Measured Ports dialog (Meas is on).
•
Connector
provides a drop-down list to select the connector type An (f) behind the connector type
denotes female connectors, an (m) denotes male connectors. Symmetric (sexless) connectors
(e.g. PC7) are not labeled. User-defined connectors can be added or removed in the
Available
Connector Types dialog, which is opened from the Channel – Calibration – Calibration Kits
dialog. at the port and its gender. If Same Connector at All Ports in Table is active, the
connector types at all ports (but not their gender) are always adjusted to the current selection.
Non-uniform connector types
In the present firmware versions the connector types at all ports must be equal. If different types
are selected the analyzer displays an error message.
•
Ref. Imp. shows the reference impedance for the selected connector.
•
Calibration Kits
provides a drop-down list to select a calibration kit. The list contains all calibration kits available
for the selected connector type. The assignment of a calibration kit to a connector type must be
the same for all physical ports: If a calibration kit is changed, the analyzer automatically assigns
the new kit to all ports with the same connector type.
Support of calibration types
The selected calibration kit must contain all standards needed for the active calibration type. If it
doesn't the analyzer displays an error message.
Waveguide cutoff
If a user-defined waveguide connector is assigned to one of the calibrated ports, then the start
frequency of the active channel must be above the waveguide cutoff. Otherwise the analyzer
displays an error message.
Import Kit opens the Import Calibration Kit dialog to load and (if desired) activate a cal kit file. Next >
opens the second dialog of the wizard to continue the calibration procedure:
•
In a user-defined (Other...) calibration, the Compile Calibrations dialog is called up.
•
In a predefined calibration, Compile Calibrations is skipped and the Measure Standards dialog
is called up.
If the calibrated channel has already been assigned to a cal group, the correction data overwrites
the cal group data, so the new calibration will affect all channels assigned to the cal group. The
network analyzer generates a notice message "New calibration will overwrite cal pool!" when
opening the Select Physical Port Connectors dialog.
Checks on switching to the next dialog
When the Next> buttonis pressed the analyzer checks the calibration kits and the matching of the
calibration standards and possibly displays a notice box (confirm with OK). This happens:
•
If one of the calibration kits is described by dummy kit parameters or typical values.
•
If a predefined 7-term calibration method TXX (TOM, TRL, TNA, TRM) is selected but one of
