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 port(s).
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 simply 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:
[SENSe<Ch>:]CORRection:COLLect:METHod:DEFine
Calibrate all Channels
Check this box to apply the acquired correction data to all channels in the active recall
set. Leave it unchecked (preset setting) to apply them only to the active channel.
Note that this option is available only if the active recall set contains multiple channels.
Remote command:
[SENSe:]CORRection:COLLect:CHANnels:ALL
Select All/Deselect All
Selects/deselects all ports.
These buttons are only shown if more than 4 ports are available.
