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.
Type/Source
Selects the calibration type. The green arrow symbols give a preview of the type and
the number of calibration sweeps involved:
●
Curved arrows (example: "Refl Norm Open") denote one or more reflection mea-
surements at each port.
Reflection calibration types can be used for any set of test ports: reflection calibra-
tions are repeated for each port.
●
Straight, horizontal arrows (example: "Trans Norm") denote one or more transmis-
sion measurements between each pair of two ports.
Transmission calibration types require at least two physical ports. For unidirectional
transmission calibration types ("Trans Norm", "One Path Two Ports"), the
(
"Source"
port) must be specified in addition.
●
The full n-port calibration types (n > 1, e.g. "TOSM") are symbolized by a closed
square symbol. The number of arrows increases the complexity but can also
improve the accuracy of the calibration.

Remote command:

Select All/Deselect All
Selects/deselects all ports.
These buttons are only shown if more than 4 ports are available.
Step 2: Connectors and Cal Kits
Selects the connector type, gender and cal kit for all ports and allows you to import a
calibration kit.
