selected in the Start Cal submenu. For a user-defined calibration (Start Cal – Other...) all
measurement ports of the analyzer are displayed regardless of their port configuration.
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 port configuration
dialog (Meas is on), and if the RF source power is not switched off (RF Off is off).
 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 is active, the connector types at all ports (but not their gender) are always adjusted to the
current selection. If Same Gender at All Ports is active, the genders at all ports (but not the
connector type) are always adjusted to the current selection.
 Char. Imp. shows the characteristic impedance for the selected connector.
 Calibration Kit
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.
Completness: 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.
 Kit Modified
This column is only visible if When Starting a New Cal, Show Date of Last Cal Kit Modification is
activated in the Calibration tab of the System Config dialog.
For a user-defined calibration kit, it displays the kit's date of last modification.
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.
Detector selects the detector settings for the S-parameters which the analyzer uses during the calibration.
The average (AVG) detector eliminates noise contributions which are superimposed on the measured
signal; it is needed for noise figure measurements using option R&S ZVAB-K30. The Normal detector is
recommended for all other applications.
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.
Same Sweep Setup for All Standards selects one of two alternative calibration methods:
