The Port2DevPair key has two purposes. First it identifies the calibration device that is connected to the PNA port 2. Second it specifies that PNA port 2 will be used in any calibration that references the path configuration.

The value of this key must be a Device Port Pair where the device is defined in the configuration file. It should be noted that if the calibration type will be using the devices stored characterization file (such as ExtendWithFcmFile) that the DevPair should include the output port. However, if an output port is not included in the DevPair the output port will default to the input port incremented by 1.

The 'Port2DevPair' key can be omitted if the path is not referenced by a Calibration and only used to set the RF switch path. Typically the path identifies the switch path and the cal devices together.

An Example:

; Path configuration example

[ICM_PATH_2Port_1_3]

Port1DevPair = FCM_1:1
Port3DevPair = FCM_3:1
SwitchPath = ICM_SW01:1,ICM_SW02:1,ICM_SW03:1,ICM_SW04:1,ICM_SW10:0
