'Selector String Cannot Contain Signal String' Error When Performing Manual Calibration with RFmx VNA

Issue Details

When attempting to perform a manual calibration with the PXIe-5633, I am getting the error Selector string cannot contain signal string (Parameter 'selectorString') as shown below. 

Solution

This is a known bug with RFmx VNA 2025Q1. A fix for this issue has been included into the RFmx VNA 2025Q2 version. 

This error may occur if you are using the PXIe-5633 from InstrumentStudio in the debug/control mode or if you have saved and reloaded the panel. If you are using debug/control mode from InstrumentStudio, switch to standalone mode with a panel that has not been reloaded and try again. 

If you are still receiving this error, please install RFmx VNA 2025Q2 or later. 

Additional Information

It is recommended to have all NI RF software that is installed be the same version. If you need to install RFmx VNA 2025Q2, then it is recommended to also upgrade/install any other RFmx software and NI-RFSA/RFSG to version 2025Q2. Releases for RFmx and NI-RFSA/RFSG are published at the same time.
