Highlights
The M9046A PXIe 18-slot chassis delivers the power and cooling required for high-performance applications. It includes 3 PXIe hybrid slots which gives the system designer the flexibility to mix PXIe and hybrid-compatible modules. With its Gen 3 backplane and x24 system slot, it is ready to tackle high-data bandwidth applications.
The M9046A is new from the ground up including a new power supply design providing unprecedented power per-slot capabilities with the ability to monitor power and control switching frequency on a per-slot basis. With improved airflow, the improvement in cooling performance results in superior acoustic performance with up to a maximum of 85 watts per slot. The chassis is also designed for easy integration into large systems containing multiple PXIe chassis and other non-PXI instrumentation including access to 8 hardware trigger lines without consuming a slot.
Cooling high-power PXI Modules (>38W) is complex and has many variables. Variations in Chassis and Module designs result in different cooling characteristics, such as cooling per slot and the cooling profile across a module within a slot that can impact the modules specifications and safety.
Due to that complexity and lack of an interoperable standard, high-power PXI Chassis and Modules from different companies were designed separately and may not be interoperable. Currently, there is not an initiative within the PXISA to try to specify a mechanism for guaranteeing interoperability, so it is recommended that you use the high-power PXI Chassis from the same company you are purchasing the high-power PXI Module from.
- 3 PXIe hybrid slots, 13 PXIe slots, 1 PXIe timing slot, and 1 PXIe system slot

Key Specifications

M9046A Cooling
The M9046A chassis utilizes a new chassis cooling system with an increased volume of airflow resulting in a superb per-slot cooling system while producing a lower level of acoustical noise.
Three auto-speed fans on the rear panel pull in cooling air and unlike other PXI chassis, auto mode can be used over the full operating temperature range of the chassis.
