Introduction

The ESM:
• runs the chassis embedded operating system (Windows 7) which
manages all internal tasks and communications.
• tracks inserted modules and manages power requirements.
• monitors chassis temperature and controls variable- speed chassis
fans.
• monitors module sensors and reports component failures to a system
log.
• acts as a Gigabit Ethernet switch; forwards frames along the backplane.
• connects an external host computer to the chassis.
• synchronizes timing across all modules through the Keysight Trigger
Bus, using an internal or external clock source.
LAN connector on AXIe ESM is not used. Only use LAN connection on the
host computer.
Either the PCIe (desktop only) or USB (desktop or laptop) port can be used
in this ESM but not both simultaneously. When you use the PCIe port, the
USB port is automatically disabled until the PCIe port is no longer in use.
Keysight M9537A AXIe Embedded Controller Module
The M9537A AXIe Embedded Controller is a one slot module that you can
install in the M9505A AXIe chassis like any other instrument module. This
module acts as a host computer when installed in the M9505A AXIe
chassis. It is always installed in slot 1 of the M9505A AXIe chassis.
The following figure displays this module.
