The Keysight M9505A is an AXIe 1.0-compliant 5-slot chassis designed to host high-performance instrument modules for advanced test and measurement systems. An integrated embedded system module (ESM) manages chassis operations without consuming a standard instrument slot, maximizing available space for instrumentation. The platform delivers 4 GB/s system bandwidth and supports module-to-module data rates up to 2 GB/s, making it suited for demanding applications across aerospace and defense, computation, communications, electronics test, and semiconductor testing.
