Keysight/Agilent M9521A AXIe System Module
The M9521A AXIe System Module from Keysight/Agilent is located at the top end of a 14-slot chassis, which connects up to 13 different AXIe Instrument Payloads to a desktop computer via a Gen 2 X8 PCIe connection and also provides Gigabit Ethernet connectivity from the rear panel. Internally, this AXIe system module allocates a separate Gen 2 X4 PCIe lane and LAN connection for each of the 13 AXIe payload slots. This eliminates data bottlenecking on the internal connections. As well as providing AXIe 1.0 and AXIe 2.0 compliant operation, the Keysight M9521A will distribute a precision 100 MHz clock signal, route star triggers, and provide an IPMB controller to enable sequencing of module power-on commands and also temperature sensor monitoring across the entire chassis.
In addition to these features, the M9521A's built-in multi-frame synchronization will help simplify the orchestration of multiple chassis. In order to connect additional chassis together, two Front Panel X8 PCIe Cable Ports are available for daisy-chaining up to three 14-slot AXIe chassis together or connecting PXIe enclosure systems together. This capability will allow users to create hybrid test platforms utilizing both PXIe and AXIe enclosures without the need for additional external switches. The AXIe System Module will distribute a common reference clock signal and trigger signals to provide tight picosecond alignment for semiconductor parametric test applications, phased array radar simulation applications, and high-energy physics experiments requiring high channel count, precise synchronized sampling across hundreds of channels. The elimination of the need for extensive amounts of external cables will reduce costs associated with cables, installation, and maintenance. Additionally, the Keysight/Agilent M9521A utilizes Gigabit LAN interface connectivity for remote access to instruments, health monitoring of instruments, and firmware updates over standard corporate networks.
In various applications such as aerospace, defense, and electronics manufacturing testing, the Keysight M9521A System Module has been used successfully to consolidate control links and data links into one front panel unit, allowing engineers to utilize all 13 available payload slots for digitizers and arbitrary waveform generators. The AXIe System Module is designed to work with the Chassis Push-Pull Cooling Design and can be installed with removable fan tray assemblies in the front of the chassis to ensure reliable operation even when subjected to extreme thermal loads. By providing high-bandwidth PCIe switching capabilities, deterministic multi-chassis sync capability, and dual LAN/PCIe control functionality, automation engineers can now design and implement highly dense, instrumented, scalable multi-instrument test systems that provide continuous high-speed data streaming and measurement coordination functions. The modular nature of this solution reduces maintenance costs by eliminating the need for service technicians to reroute extensive amounts of cabled connections during field service activities.
