Issue Details

Is it possible to merge or stack different types of Source Measure Units (SMUs) in a single setup? 

 

Solution

Mixing different SMU model types in a stacked or ganged configuration is not recommended.

For best practices and detailed guidance, refer to our most comprehensive documentation on stacking and ganging SMUs. One of the key recommendations is to use identical SMU models to ensure consistent performance and safe operation across all units.
