Access: Calibration Unit Wizard (MultiCal), Step 1: "Ports" > "Add..." / "Modify..."
●
The "Multiple Cal in Calibration Wizard" (MultiCal) feature is disabled by default
and has to be activated in the Calibration Tab of the "System Config" dialog.
●
For background information on calibration types, see Chapter 5.5.1, "Calibration
Types", on page 148.
The layout of the main panel depends on the number of test ports available.

Ports
Selects the test ports to be calibrated.
Note: Calibration and port de-/activation.
The way the analyzer fimware activates/deactivates ports after a successfull calibration
(system error correction or power calibration) has slightly changed:
●
In all FW releases, calibrated ports that were previously disabled, are automatically
enabled as single-ended logical ports.
●
Starting with FW version 2.10, uncalibrated ports were disabled in the related
channel(s). If only one of the physical ports forming a balanced port was calibrated,
the balanced port was dissolved and only the uncalibrated (single-ended) port was
disabled.
In earlier FW versions there was no such port deactivation mechanism.
●
Since FW version 2.40 an uncalibrated port is only disabled if it is not used by a
measurement, i.e. if it is not required by any trace of the related channel.
Remote command:
The port parameters in many calibration commands define the calibrated ports.
