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.
For an overview, refer to Table 5-7.
Remote command:
[SENSe<Ch>:]CORRection:COLLect:METHod:DEFine
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.
