Modular Systems

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.

The Keysight M9019A PXIe 18-slot Gen 3 chassis delivers the flexibility, compatibility, and performance required for demanding applications. With 16 PXIe hybrid slots, it gives the system designer more flexibility to mix and match the number and location of PXIe and hybrid-compatible modules. The ultra-high performance, PCIe® switch fabric can operate up to Gen 3 providing up to 24 GB/s of system data bandwidth. Combine the M9019A with the M9022A/23A/24A PXIe System Modules and M9048B/49A PCIe Desktop Adapters to achieve up to a Gen 3 x16 PCIe link to an external PC.

The M9019A has an innovative cooling design which allows the chassis to fit into 4U of rack space in most cases. When combined with the latest 1U rack-mounted computer, a powerful system can be built in only 5U of rack space. Additionally, optional “air-inlet” modules can be used to supply more cool air from the front of the chassis.
