Would All RFmx Settings Be Reconfigured When Changing from One List to Another If No Change Is Used?

Issue Details

I am trying to improve test speed in our RFmx setup and wanted to know how RFmx 20.5 behaves when switching between Configuration Lists. Specifically, I am using Limited Configuration Change property set to No Change, and I am curious whether RFmx will reconfigure all settings or only the ones that differ between lists. We are using named signal configuration and frequency sweeps, so understanding this behavior is important for optimizing performance.

Solution

When you switch between Configuration Lists in RFmx, even with Limited Configuration Change property set to No Change, RFmx does not compare settings between lists. Instead, it treats each list as a separate configuration and reconfigures all settings, regardless of whether they have changed. The Limited Configuration Change property is not intended to be used when changing from one configuration list to another. 

To improve test speed, you should:

• Minimize switching between configuration lists during a session.
• Reuse named signal configurations wherever possible.
• Consider using RF List Mode along with advanced optimizations like precomputed acquisition reuse and multi-measurement parallelism to improve test speed and efficiency. These features allow you to sequence through multiple RF configurations with minimal reconfiguration overhead.
