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.
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.
