Note:
Calibration and port de-/activation.
The analyzer fimware automatically activates/deactivates ports during/after a (success-
ful) calibration:
●
Calibrated ports that were previously disabled, are automatically enabled as single-
ended logical ports.
●
An uncalibrated port that is not used by a measurement (i.e. the port is not required
by any trace of the related channel) is disabled.
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.

Calibrate all Channels
Check this box to apply the acquired correction data to all channels in the active chan-
nel setup. Leave it unchecked (preset setting) to apply them only to the active channel.
Note that this option is available only if the active channel setup contains multiple
channels.
Remote command:
[SENSe:]CORRection:COLLect:CHANnels:ALL

tion kit.
