Description

This property replaces ECALPortMap Property

Specifies which ports of the ECal module are connected to which ports of the VNA for the DoECAL1PortEx and DoECAL2PortEx methods when the OrientECALModule property = False.

This setting remains until the VNA is restarted or this command is sent again.

Note: For guided calibrations where Orient is OFF and the same ECal module is used in more than one Connection Step, you are not allowed to specify how the ECal module is connected.  Instead, the VNA determines the orientation.  The VNA does not verify that you made the connection properly.

This command, and OrientECALModule_Property, can be used to perform ECal orientation using the Guided Calibration interface.

 VB Syntax

cal.ECALPortMapEx (module) = value

Variable

(Type) - Description

cal

A Calibrator (object)

module

(long integer)  Optional argument. ECal module.

Choose from modules 1 through 8

Use IsECALModuleFoundEx to determine the number of modules connected to the VNA

Use GetECALModuleInfoEx to return the model and serial number of each module.

value

(string) -Format this parameter in the following manner:

Aw,Bx,Cy,Dz

where

• A, B, C, and D are literal ports on the ECAL module

• w,x,y, and z are substituted for VNA port numbers to which the ECAL module port is connected.

Ports of the module which are not used are omitted from the string.

For example, on a 4-port ECal module with

• port A connected to VNA port 2

• port B connected to VNA port 3

• port C not connected

• port D connected to VNA port 1

the string would be: A2,B3,D1

DoECAL1PortEx or DoECAL2PortEx methods will fail if the port numbers passed to those methods are not in the string of this property and OrientECALModule property = False.

Return Type

String

Default

Not Applicable

Examples

Dim cal As Calibrator
Dim sPortMap As String
Set cal = PNAapp.ActiveChannel.Calibrator
cal.ECALPortMapEx = “a2,b1” 'Write
sPortMap = cal.ECALPortMap 'Read
