Hello Keysight experts.

Due to My N5290A system works not well recently, I did system recovery then upgraded the firmware back to version A12.85.08 which it was. 

However, when I tried to change operation mode from “Standard PNA” to “N5290A broadband system”, the error message ”invalid configuration” always shows in the same application window.

I have checked all my connections, and the system can recognize my N5292A and extenders correctly,too.

Somehow I just can’t change to mmWave mode as well.

Is there anything I missed or I should check agian?

Thank you.

Correct Answer

Hello,

 

It turns out that in the past when I saw this issue come up it was due to having a corrupted configuration file for the mm-wave setup. So the best way to resolve this type of issue is to find the following file:

 

C:\ProgramData\Keysight\Network Analyzer\mmheadconfiglist5

 

Then remove the file and the restart the VNA application and try to access the mm-wave dialog.

 

Note the ProgramData directory is a hidden directory.

 

Regards

Suren
