Issue Details

I'm using the PXI Advisor to build a PXI system. When I select a chassis with a fan underneath the card slots such as the PXIe 1078, PXIe-1071, PXIe-1073 and PXIe-1088 chassis, all the 449x DSA and 446x modules appear grayed out. Why I can't select a 449x or 446x module using these chassis? 

Solution

Use a high-performance chassis (like the PXIe-1092) or any chassis where the fans aren't located on the bottom of the chassis. 

Additional Information

The 449x and 446x DSA modules high-sensitivity cards that are meant to operate in specific conditions. However, some chassis such as the 107x series and the 1088 have fans on the bottom, which introduces electrical and mechanical noise that the modules pick up. This raises the noise floor of the DSA card causing it to be out of spec inside these chassis.
