The ShortOpenLoad configuration is used for defining manual short, open and load characterizations. See Short Open Load Characterization for an understanding of how this configuration would be utilized in a program.

ShortOpenLoad configurations are identified by the ConfigType equal to the value "ShortOpenLoad". While ShortOpenLoad configurations have many of the same keys as a Path configuration they are never associated with a Calibration configuration. A ShortOpenLoad is only associated with and defines a characterization requiring operator interaction.

An important note:

Unlike a Path configuration the Port(x)DevPair values do not determine which PNA ports are being characterized. This key only specifies which devices will be put in a thru state before a measurement is made. The Port(x)DevPair can be omitted if there is no calibration device in the path that needs to be put in the thru state.

The Port(x)PrefixToUse key specifies the prefix to be applied to all generated files. Specifying a prefix on a port determines which PNA ports will be used.

The following defines a 2 port (ports 1 and 2) ShortOpenLoad characterization.

[SOL]
AutoAntiAliasing = 1
CalAcquireTimeoutSec = 60
CalSetToActivate = CalSetToUseName
ConfigType = ShortOpenLoad
DirectoryToUse = C:\Temp
Port1DevPair = ICM_FCM1:1
Port2DevPair = ICM_FCM2:1
Port1PrefixToUse = Port1
Port2PrefixToUse = Port2
SwitchPath = ICM_SW01:1,ICM_SW02:1,ICM_SW03:1,ICM_SW04:1,ICM_SW10:1



In the above example:

When a two port ShortOpenLoad characterization on ports 1 and 2 of the PNA is desired then 'Port1PrefixToUse' and ''Port2PrefixToUse' must be set to a string that will identify the data files associated with these ports.

The switch path should be configured to route RF signals from Port 1 and 2 of the PNA to the ShortOpenLoad reference plane attached to those ports (optional).

Port1DevPair and Port2DevPair need only define a calibration device that is in the RF path and needs to be set to a thru state prior to the measurement (optional).

From the above example:

The ShortOpenLoad section specifies that port 1 and port 2 of the PNA will be used in the measurement and that the data files stored will have the prefix "Port1" and "Port2" respectively :

Port1PrefixToUse = Port1
Port2PrefixToUse = Port2


The ShortOpenLoad section specifies that FCM_1 and FCM_2 are to be set to a thru state before the measurement is made.

Port1DevPair = FCM_1:1
Port2DevPair = FCM_2:1


The path sets the switches on the ICM to a through test state for ports 1 and 2:

SwitchPath = ICM_SW01:1,ICM_SW02:1
