A switch path that establishes the unknown through path from port 1 to port 2 during calibration. This path will only be activated during the through measurement.

Calibrations of the following type use this value.

This key must be defined if the ThruPortPairs list includes the pair "1:2".

The value of this key is typically a reference to an already defined path configuration section name. In this case the path is taken from the referenced configuration section.

The switch pairs listed in the path do not necessarily have to be controlled by the same MultiSwitch. If there the system is part of a complex matrix that has more than one MultiSwitch controller switches from any controller can be mixed in to the switch path. When the path is set all the switches will be in the required positions.

See the configuration nomenclature for Switch Pair and also Switch Paths.
