M9502A
M9502A 2-slot AXIe chassis for transportable applications. Includes embedded system module and Gen 2, x8 link to external controller.
The M9502A AXIe Chassis is fully compatible with the AXIe 1.0 specification. It includes an embedded system module (ESM) that does not take up an instrument slot. This system module performs the chassis management functions contained in the AXIe specification. Additionally, it provides PCI and LAN interfaces for connection to an external computer, external clock and trigger connectors, and Keysight-exclusive, inter-chassis synchronization connectors. The local bus implemented in the M9502A provides the maximum 62 pairs allowed by the AXIe specification. Combine the M9502A with the M9048A PCIe Desktop Adaptor to achieve the highest system bandwidth.
The M9502A is perfect for transportable applications that require a higher performance of AXIe. It can also be installed in a rack and the instrument modules slots are arranged horizontally to minimize rack space. This arrangement combined with a high-performance cooling system allows the chassis to be racked in only 2U of space. The M9502A is also designed to be easily maintained as both the power supply and fan tray can be removed while the chassis remains in the rack.
M9505A
M9505A 5-slot AXIe chassis with embedded system module and Gen 2, x8 link to external controller. It is fully compatible with the AXIe 1.0 specification.
The M9505A AXIe Chassis is fully compatible with the AXIe 1.0 specification. It includes an embedded system module (ESM) that does not take up an instrument slot. This system module performs the chassis management functions contained in the AXIe specification. Additionally, it provides PCI and LAN interfaces for connection to an external computer, external clock and trigger connectors, and Keysight-exclusive, inter-chassis synchronization connectors. The local bus implemented in the M9505A provides the maximum 62 pairs allowed by the AXIe specification. Combine the M9505A with the M9048A PCIe Desktop Adaptor to achieve the highest system bandwidth.
The instrument modules slots are arranged horizontally to minimize rack space. This arrangement combined with a high-performance cooling system allows the chassis to be racked in only 4U of space. The M9505A is also designed to be easily maintained as both the power supply and fan tray can be removed while the chassis remains in the rack.

M9506A
5-slot AXIe chassis with embedded system module, Gen 3 performance, 300W per slot, and GPS option.
The Keysight M9506A is a high-performance AXIe chassis and is the best choice for demanding, modular applications. The chassis is compliant with the AXIe 1.0 Rev 3.0 Wide-AXIe specification. It provides 5 slots for AXIe instrument modules, up to 300 watts per slot, and includes an embedded system module that does not take up an instrument slot. The embedded system module (ESM) provides a Gen 3 x8/x16 PCIe® interfaces for connecting the chassis to an external controller or expanding the system using multiple chassis. To minimize rack space, the instrument module slots are arranged horizontally. The chassis is the quietest AXIe chassis available with its new cooling design.
The M9506A-BC1 options adds a closed, instrument-grade, Linux-based controller to the back of the M9506A chassis. It was developed to enhance security for high channel count digitizer applications, bringing the ease of use of traditional benchtop together with the benefits of a modular platform. A simple LAN connection gives you easy SCPI based control of many channels in a small space.
The M9506A-GPS option adds GPS synchronization ability along with an external antenna port on the front panel. It provides an accurate 1 PPS output and the 10/100 MHz reference can be locked to this clock. The PPS signal can be propagated to trigger I/O and trigger events can be timestamped. Other GPS information is also provided including latitude, longitude, and altitude.
