AB Split configurations define the parameters used for AB Split characterizations and where they will be stored. See AB Split Characterizations for an understanding of how this configuration would be utilized in a program.

AB Split configurations are identified by the ConfigType equal to the value "AbSplit".

Important notes:

  • AB split characterizations always require a 2 port calibration prior to execution.
  • The ThruPortPair specifies the two PNA ports used and defines the thru measurement.
  • 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 following example defines an AB split on ports 1 and 2.

; AbSplit configuration example
;*******************************************************************************
[ABSPLIT_1]
CalAcquireTimeoutSec = 60
CalSetToActivate = CalSetToUseName
ConfigType = AbSplit
DirectoryToUse = C:\Temp
Port1DevPair = FCM_1:1
Port2DevPair = FCM_2:1
ThruPortPair = 1:2
SwitchPath = ICM_SW01:1,ICM_SW02:1,ICM_SW03:1,ICM_SW04:1,ICM_SW10:0


In the above example:

The switch path should be configured to route RF signals from Port 1 and 2 of the PNA to the calibration devices attached to those ports.

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

The above example the ThruPortPair specifies that port 1 and port 2 of the PNA will be used in the measurement:

ThruPortPair = 1:2


FCM_1 and FCM_2  (see DevPair) are to be set to a thru state before the measurement is made.

Port1DevPair = FCM_1:1
Port2DevPair = FCM_2:1


The switch path specifies the switch states to put the ICM to a through test state for ports 1 and 2:

SwitchPath = ICM_SW01:1,ICM_SW02:1,ICM_SW03:1,ICM_SW04:1,ICM_SW10:0
