ECAL module property failures

Hi,
I have a ECAL module (N4690-60005) connected to a PNA (N5230C) I have the following isssues when using Visual basic 6 and COM to control the instrument.

I am able to perform a full two port calibration of the PNA using the ECAL module through the guided calibration object without any errors, however:
When using the ECALCharacterizationEx property to specify the user characterisation (1) to apply for calibration, I expect an error message if there is no user characterisation data saved in the ECAL module, however no error message is generated. Is this expected behaviour ?

The GetECALModuleInfoEx method returns an empty string even though the specified Ecal module is connected to the PNA. Also the IsECALModuleFoundEx boolean property returns false. I have tried varying the module number from 1 through to 8 without success. In both cases the PNA does not return any error message.

The PNA firmware version is A.09.22.15  using  type library 1.9.

Thanks in advance for your help

Regards
James
