If necessary, return the product to a Keysight Technologies Sales and Service Office for service and repair to ensure the safety features are maintained. DO NOT block the primary disconnect The primary disconnect device is the appliance connector/power cord when a chassis used by itself, but when installed into a rack or system the disconnect may be impaired and must be considered part of the installation. Do Not Modify the Instrument Do not install substitute parts or perform any unauthorized modification to the product. Return the product to a Keysight Sales and Service Office to ensure that safety features are maintained. In Case of Damage Instruments that appear damaged or defective should be made inoperative and secured against unintended operation until they can be repaired by qualified service personnel Do NOT block vents and fan exhaust: To ensure adequate cooling and ventilation, leave a gap of at least 50mm (2") around vent holes on both sides of the chassis. Do NOT operate with empty slots: To ensure proper cooling and avoid damaging equipment, fill each empty slot with an AXIe filler panel module. Do NOT stack free-standing chassis: Stacked chassis should be rackmounted. All modules are grounded through the chassis: During installation, tighten each module's retaining screws to secure the module to the chassis and to make the ground connection. Operator is responsible to maintain safe operating conditions. To ensure safe operating conditions, modules should not be operated beyond the full temperature range specified in the Environmental and physical specification. Exceeding safe operating conditions can result in shorter lifespan, improper module performance and user safety issues. When the modules are in use and operation within the specified full temperature range is not maintained, module surface temperatures may exceed safe handling conditions which can cause discomfort or burns if touched. In the event of a module exceeding the full temperature range, always allow the module to cool before touching or removing modules from the chassis. Safety Symbols A CAUTION denotes a hazard.

IO Libraries Suite version 16.3 update 1 (or later) is required for multiple chassis operation. Always use the latest version of chassis firmware, IVI and LabVIEW drivers, and IO Libraries Suite to get the best performance and latest features. 1 Introduction AXIe Chassis Description AXIe Chassis Description The Keysight M9502A (2-slot) and M9505A (5-slot) AXIe chassis are modular instrument chassis fully compatible with the AXIe 1.0 specification. They allow multiple application-specific instrument modules to share a common chassis frame, power supply, cooling system, PCI Express (PCIe) Gen 2 data bus, Gigabit LAN hub, local bus for module-to-module signaling, and host PC connections. Multiple chassis may be interconnected for scalability, in either a multiple chassis or MultiFrame configuration; see “Using Multiple Chassis” on page 42 for more information. The full rack chassis provides (two or five) general purpose peripheral slots that accept 1U AXIe instrument modules. Each module slot is supplied with a Gen 2 x4 link (maximum of 2 GB/s data rate per module) to the chassis primary data ‘fabric’ hub—a x8 PCIe switch and data bus. Both chassis include a half-height Embedded System Module (ESM) which manages chassis functions. The ESM provides all ATCA shelf manager functions, plus these AXIe extensions: - provides host PC connectivity (Gen 2 PCIe x8 and/or Ethernet) - sources timing signals (CLK100, SYNC and FCLK) - routes STRIG (Star Trigger) to instruments through the backplane - routes trigger signals through an external parallel trigger bus - provides backplane PCIe and Ethernet communication between modules Other than a Power button and instrument status light, all monitoring, control and communication with the chassis requires a host PC. This can be an embedded controller such as the Keysight M9536A (a Windows-based PC specifically designed for use in an AXIe chassis) or remote (a rackmount, desktop, or laptop PC). The shared Gen 2 x8 PCIe interface from the ESM to an external host PC provides up to a 4 GB/s data rate shared among installed modules. In order for a computer to serve as host PC, its BIOS must support enumeration of PCIe slots in the AXIe chassis; many computers are not capable of enumerating a sufficient number of PCIe slots to ensure that slots in an external chassis are enumerated. Keysight maintains a document listing the integrated, rack mount, desktop and laptop computers that have been verified to properly enumerate PCIe devices in the AXIe chassis, at www.keysight.com/find/axie-chassis. For general host PC requirements, such as operating system and RAM requirements, please refer to the M9502A/M9505A AXIe Chassis Startup Guide. 2 Keysight M9502A/M9505A AXIe Chassis User Guide AXIe Chassis Description Introduction For the ESM and for each other installed module, appropriate control software and instrument drivers must be installed on the host PC.

Red indicates a power-up error. Both lights on (amber) indicates the chassis is powered on and booting. Keysight M9502A/M9505A AXIe Chassis User Guide AXIe Embedded System Module (ESM) Option U20 with USB Introduction AXIe Embedded System Module (ESM) Option U20 with USB The Option U20 ESM provides the same features as the standard ESM and adds a USB 2.0 port*. The USB port is supported only for specific Keysight AXIe modules and software. Refer to the documentation for the supported modules and software for USB use and operating instructions. This USB port provides the following features: - It enables using the AXIe chassis and the supported USB compatible AXIe modules and software with any host controller that has a USB 2.0 port. USB - Either the USB port or the PCIe port may be used -- but not both simultaneously. To change connectivity between USB and PCIe, power down the chassis and host PC. Connect either a USB or PCIe cable, but not both. Power up the system. - USB provides easy PC connectivity and uses less expensive and longer cables than PCIe. USB is physically hot pluggable, however you must restart the software controlling the module(s) when a USB connectivity change is made. You do not need to reboot the chassis or host PC. - USB provides control for the chassis and the Keysight Logic Analysis and Protocol Test Modules but not other AXIe modules. USB-compatible and PCIe compatible modules cannot be used at the same time. If you are controlling an AXIe module via USB, you must change cable connections and reboot the host PC before controlling an AXIe module via PCIe. STOP! IMPORTANT: The installation and setup information in this manual is generic. The USB port is supported only through specific Keysight software applications and modules such as the Keysight logic and protocol analyzer software and modules. These AXIe systems that use the USB port may require a different installation and setup procedure than described in this manual. Refer to the installation documentation supplied with your AXIe module or system for detailed installation information. Some AXIe test system software applications, such as the Keysight logic and protocol analyzer software and modules, sets and uses specific trigger lines in the AXIe chassis. Do not use the AXIe chassis Soft Front Panel (SFP) software or the AXIe chassis web interface to set or reroute any of the AXIe chassis trigger lines. Rerouting any of the trigger lines may cause the application software to not function correctly. * The USB port requires AXIe chassis firmware 1.3.37 or later. Refer to M9502A/M9505A User Guide. Keysight M9502A/M9505A AXIe Chassis User Guide 9 Introduction AXIe Instrument Modules AXIe Instrument Modules The chassis slots accept AXIe instrument modules. These may comprise one or more instruments for signal injection, data acquisition, and measurement. Install them in any available AXIe slot. There are two special type of instrument modules which—if used—are most typically installed in slot 1 (consult the module vendor for specific slot placement requirements). - An instrument hub module — a specialty instrument module which also acts as a hub for a secondary vendor-defined x4 data fabric. - An integrated controller module — this is a host PC with a form factor and backplane connections specifically designed for an AXIe chassis. It uses the chassis backplane for PCIe and LAN connection to the ESM. The drawing below illustrates the AXIe module’s general layout, backplane connections and chassis fasteners, viewed from the top. Module Rear (connectors to chassis backplane) Typical AXIe Instrument Module Retaining Screw Module Insertion/Extraction Handle Module Front Panel Test connections are made at the module’s front panel. The front panel and backplane connectors will vary depending on the module. 10 Keysight M9502A/M9505A AXIe Chassis User Guide ESD Precautions Introduction ESD Precautions Keysight’s AXIe chassis and instrument modules are shipped in materials which prevent static electricity damage. These instruments should only be removed from the packaging in an anti-static area ensuring that correct anti-static precautions are taken. Store all modules in anti-static envelopes when not installed. Electrostatic discharge (ESD) can damage or destroy electronic components. All work on electronic assemblies should be performed at a static-safe work station. The following figure shows an example of a static-safe work station using two types of ESD protection. Purchase acceptable ESD accessories from your local supplier. - Conductive table-mat and wrist-strap combination. - Conductive floor-mat and heel-strap combination. Both types, when used together, provide a significant level of ESD protection. Of the two, only the table-mat and wrist-strap combination provides adequate ESD protection when used alone. To ensure user safety, the static-safe accessories must provide at least 1 M of isolation from ground. Keysight M9502A/M9505A AXIe Chassis User Guide 11 Introduction Power-Up and Power-Down Power-Up and Power-Down Circuit Breaker The chassis circuit breaker is a toggle switch, marked OFF (O) when open and ON (I) when closed: Circuit Breaker Open (OFF) Circuit Breaker Closed (ON) ON/STANDBY Switch The chassis’ button on the front of the chassis is the ON/STANDBY switch, lit when the chassis is ON: STANDBY (off if power is disconnected or breaker is open) ON Power Modes The chassis has three power modes: OFF With the power cord removed or the circuit breaker in the open position, the chassis is OFF. STANDBY With the power cord connected, the circuit breaker closed, and the front panel switch in the standby (not depressed) position, the chassis is in STANDBY mode. Although no power is supplied to the ESM and installed modules when in Standby, the chassis is energized and consumes power. Fans may operate. ON With the power cord attached, circuit breaker closed, and the front panel switch in the ON (depressed) position, the chassis is ON. Power is supplied to the ESM and installed modules. Fans will operate as dictated by chassis thermal load. 12 Keysight M9502A/M9505A AXIe Chassis User Guide Power-Up and Power-Down Introduction To Power Up the Chassis Plug-In Chassis Using the supplied cord, connect the chassis to an appropriate AC power main. Close Circuit Breaker Close the rear panel circuit breaker Press On/Standby Button light when depressed Press the chassis’ ON/STANDBY switch. It should The STATUS light on the ESM will cycle as follows: 1 Light off - with button in STANDBY mode 2 Amber, steady - after pressing switch, ESM is performing a power-on self-test (POST) 3 Green, blinking - for a few seconds after POST 4 Green, steady - successful chassis power-up is complete 1 2 4 The chassis and host PC must be powered up and down in the following sequence. The chassis should be powered up first, which will initiate its built-in self test. During self test, the chassis STATUS LED will be amber. The STATUS LED will blink green and then stay green continuously when the ESM is ready. The ESM then powers up each module slot. The remote host PC should be turned on only after all installed modules have performed their initialization—see your module documentation for initialization information. An embedded controller such as the M9536A handles this sequence automatically. Keysight M9502A/M9505A AXIe Chassis User Guide 13 Introduction Power-Up and Power-Down Chassis power (High = powered up) The STATUS LED is amber at poweer-on while the chassis performs self test test. It will blink green then staay green continuously when the ESM is ready. The ESM then powers up each module slot. Chassis STATUS LED module initialization Host PC (High = turned on) The chassis must be powered up before the PC iis turnedd on to ensure that the PC BIOS will enumerate the chassis slots as the PC boots. The PC should s be turned on only after all installed moduless have performed their initialization. See your module documentation for initialization informattion. If, while the chassis was poweered down its configuration was changed down, in any way, the PC must be resstarted after Windows comes up (as indicated by the Windows splash screen). For the first-ever connection off the chassis to the PC, PC the PC mustt also be restarted as shown above. It is recommended that the PC be shut down before the chassis is powered down because many PCs don’t have the capability to safely remove (eject) PCIeconnected devices. Therefore, powering-down the chassis first can disrupt operation of the PC. In brief, the host PC must be off whenever the chassis is powered up or down. Note the need to restart the host PC (after Windows starts) if the chassis configuration has been changed in any way while the PC was turned off. Some AXIe instrument modules (also known as Blades) take longer to be ready for enumeration than the PXI link ready requirement of 100ms. Consequently, it is possible for some controllers (such as the Keysight M9536A Embedded Controller) to enumerate the chassis before all of the individual modules are ready and therefore not enumerate them. If you have a situation where Keysight Connection Expert and/or the Windows Device Manager consistently do not find specific instrument modules when the chassis powers up, increase the module initialization time. Refer to the Wait time setting in “ESM PCIe Upstream Connection Settings” on page 48. While the power sequencing shown above doesn’t apply to an embedded controller (because an embedded controller and chassis are powered simultaneously), an embedded controller must also be restarted (after Windows starts) if the chassis configuration was changed in any way while the chassis and embedded controller were turned off. 14 Keysight M9502A/M9505A AXIe Chassis User Guide Power-Up and Power-Down Introduction To Power Down the Chassis For routine power-down or to cycle power to the chassis, press the chassis ON/STANDBY switch. The main chassis fans will gradually drop in speed to off, and the PSU fans will gradually return to idle speed as the PSU cools. This is normal. If you are using an embedded controller such as the Keysight M9536A, always shut down the Windows operating system before pressing the chassis ON/STANDBY switch. Also, ensure that the embedded PC never goes into sleep or hibernate mode. It is possible for the PC to lose its chassis enumeration. For routine power-down, do not use the circuit breaker to turn the chassis off. Doing so interrupts power to the power supply fans, which could shorten the life of the PSU. Use the front panel On/Standby switch to power down the unit, and allow the PSU fans to return to idle before removing power from the chassis. Once the chassis has cooled, you may isolate the chassis from AC power as needed. This is usually done by opening the circuit breaker.

Some AXIe modules and systems require a different installation and setup procedure than described in this manual. Refer to the installation documentation supplied with your AXIe module and or system for detailed installation information. 21 Chassis Installation Planning the Installation Planning the Installation Basic Chassis Verification The M9502A/M9505A AXIe Chassis Startup Guide, provided in print and on CD with each chassis, includes a step-by-step procedure to connect the chassis to a host PC and establish basic LAN communication with the chassis using the built-in Web Interface. Keysight recommends you follow the Steps in the Startup Guide before proceeding. You may also obtain the latest Startup Guide at www.keysight.com/find/axie-chassis. To verify basic chassis operation, it is not mandatory to install modules, mount the chassis, or interconnect to other chassis. Complete Installation After basic chassis operation is verified, you can complete the installation: Install Modules Install the instrument modules in the chassis (see page 23). If you’ll be rackmounting the chassis, it is easiest to remove the bumpers (see page 30) before installing modules. Mount the Chassis If required, rackmount the chassis using an available hardware kit. You will need to remove the bumpers before rackmounting the chassis. See page 29 for instructions; this section also provides considerations for benchtop use. Make MultiFrame or Multiple Chassis Connections You may interconnect two or more AXIe chassis. For more information, see “Using Multiple Chassis” on page 42. Once Chassis Are In Place: Set Up a Host PC Reconnect the chassis to the host PC (complete instructions are in the Startup Guide). IMPORTANT: The installation and setup information in this manual is generic. Some AXIe modules and systems require a different installation and setup procedure than described in this manual. Refer to the installation documentation supplied with your AXIe module and or system for detailed installation information. Install Software You should have already installed the chassis device drivers and Keysight IO Libraries Suite on your host PC. You should now install any device drivers or Soft Front Panel software required for your installed modules. See page 34. 22 Keysight M9502A/M9505A AXIe Chassis User Guide Installing Modules Chassis Installation Verify Operation Verify that the chassis powers up correctly and that Keysight Connection Expert recognizes the chassis configuration and installed modules (see page 35). Installing Modules The AXIe chassis accept modules conforming to the single slot, 1U AXIe standard. These may include: - AXIe instrument or instrument hub* modules - AXIe embedded controller* module - AXIe filler panel modules * If used, a hub or controller module must be installed in slot 1 The insertion and removal procedures are the same for the 2-slot and 5-slot chassis, and for all module types except filler panels. Static Electricity—The components and connectors on modules are sensitive to static electricity. To minimize electrostatic damage, take the necessary anti-static precautions. Both chassis provide a grounding terminal, to which you can connect a wrist strap. To locate this terminal, see “M9502A 2-Slot AXIe Chassis at a Glance” on page 4 and “M9505A 5-Slot AXIe Chassis at a Glance” on page 6. Empty Slots—Except for performing initial chassis verification or troubleshooting, do not operate the chassis with empty slots. Always insert a filler panel module or instrument module into empty slots. This is especially important for the slots on either side of an instrument module. This allows proper air flow and cooling, and provides EMI shielding for the chassis and installed components. Leaving slots empty can increase fan speed, raise ambient noise, overheat components, and shut down modules. ESM—The Embedded System Manager is integral to the operation of the chassis. Except for troubleshooting purposes, do not remove the ESM. Hot Swap—AXIe does not explicitly support hot swap for instrument modules. Keysight recommends fully powering down the chassis before installing or removing modules Embedded Controller Module—Manually initiate a graceful shutdown of the controller operating system and power off the chassis before removing the module. The chassis is shipped with filler panel modules in all but Slot 1; you may need to remove filler panels from covered slots. Keysight M9502A/M9505A AXIe Chassis User Guide 23 Chassis Installation Installing Modules To Remove a Filler Panel Module 1 Power down and unplug the AXIe chassis. 2 Fully loosen the captive retaining screws on both sides of the filler panel. Ensure you fully loosened the captive module retaining screws before trying to extract any module. If you attempt to pull the module out by the screws (for filler panels) or by using the extraction handles (other modules) with these screws still engaged, damage to the chassis or module could result. 3 Grasp the panel by the two retaining screws, and slide it out of the chassis. To Install a Module 1 Power down and unplug the AXIe chassis (see “To Power Down the Chassis” on page 15). 2 Plan slot usage. If you are using an embedded controller module, it must be in Slot 1. If there are modules that will be removed often, insert them into the topmost slots. 24 Keysight M9502A/M9505A AXIe Chassis User Guide Installing Modules Chassis Installation 3 Locate the (left and right) guide rails for each slot. The example below shows the right side guide rails in the M9505A with all slots empty; typically one or more will be covered. The rails on the M9502A are identical, just fewer. Spring guides center the module’s PCB at the entry of the guide rail The illustrations below show the M9502A, but apply to both chassis. 4 Align the module’s circuit board with the guide rails on both ends of the chassis. If the blade has metal plates covering the board, be sure to insert the circuit board and not the metal plates into the rails. Slide the board Keysight M9502A/M9505A AXIe Chassis User Guide 25 Chassis Installation Installing Modules gently into the two rails. If the fit is tight, slide the board back out and recheck alignment. 5 Locate the insertion/extraction handles at each side of the module’s front panel. Extend the ends of both handles, by pulling them inwards towards each other; the plastic handle end slides about 1 cm on the metal handle shaft. Then fully open the handles by pivoting them out towards you until they are perpendicular to the front panel. The left handle is shown below, from the top view, correctly extended. If either handle is misaligned, you will not be able to properly install the module. 6 Slide the module completely into the chassis. When the module’s backplane connectors contact the chassis backplane, you will feel resistance and the 26 Keysight M9502A/M9505A AXIe Chassis User Guide Installing Modules Chassis Installation two handles will begin to close toward each other. The module’s faceplate will be about 1 cm from the chassis front panel. 7 Continue nudging the module faceplate gently but firmly with your thumbs, until the handles are pressed up against the chassis and the module’s front panel lies flush with the chassis’ front panel. This seats the module firmly in the chassis backplane. If necessary, gently press inward (toward the chassis) on the handles to ensure full insertion. 8 Tighten the captive retaining screws at both sides of the module. Modules are grounded through the chassis. Tighten the module retaining screws to ensure a proper ground connection. 9 Retract the handle ends by sliding them outward on their metal shafts, away from each other, toward the chassis edge; this secures them out of the way of test connections. 10 Repeat steps 4 through 9 for additional modules, as needed. Ensure that each slot has an instrument or filler panel module installed. 11 Plug in and power up the AXIe chassis. Verify that the chassis fans are operating and free of obstructions that may restrict airflow. Keysight M9502A/M9505A AXIe Chassis User Guide 27 Chassis Installation Installing Modules To Remove a Module The instructions below apply to all module types. The Embedded System Module (ESM) has the same extraction handles and retaining screws as instrument modules. If you should ever have to remove the ESM, follow the instructions for instrument modules below. 1 Power down and unplug the AXIe chassis (see page 15). 2 Fully loosen the captive retaining screws on both sides of the module. Ensure you fully loosened the captive module retaining screws before trying to extract any module. If you attempt to pull the module out by the screws (for filler panels) or by using the extraction handles (other modules) with these screws still engaged, damage to the chassis or module could result. 3 For a filler panel module, grasp the panel by the two captive retaining screws, and slide it out of the chassis. For all other modules, locate the insertion/extraction handles at each side of the module’s front panel. Extend the plastic ends of both handles by sliding them outward on their metal handle shafts, inwards towards each other. 4 Open the handles by pivoting them out towards you, away from the chassis. Place each thumb at the inside of the handle, forefinger outside the handle, and rotate the handles with your thumbs. When the handles are perpendicular with the chassis, stop. The module should now be unseated the module from the chassis backplane and its faceplate from the chassis front panel. Grasp the levers to slide the module out of the chassis. 28 Keysight M9502A/M9505A AXIe Chassis User Guide Mounting the Chassis Chassis Installation Mounting the Chassis Environmental and Power Considerations Consider your anticipated chassis weight (with modules installed), power and ventilation requirements, benchtop use and rackmounting options to ensure safety and optimize access to test and control instrumentation. Weight The 2-slot chassis weighs 7.7 kg (17 lbs), including ESM but with no other modules installed. With two instrument modules, it can weigh 15.7 kg (35 lbs). The 5-slot chassis weighs 13.3 kg (29 lbs) with ESM, and can weigh 33.3 kg (73 lbs) fully loaded. It is typically used rackmounted, but can also be used on the bench, with proper support and ventilation. AC Input The chassis will operate on 100-120VAC or 200-240VAC, with input frequency from 50-60 Hz. Maximum input power consumption is 800 VA for the M9502A, 1350 VA for the M9505A. . Avoid overload ing an electrical circuit. Ensure your power supply matches the AC Input requirements listed above. In case you need to power down the chassis in an emergency, make sure that you have clear and quick access to the primary d isconnect. If the chassis is rackmounted, this primary d isconnect can be a power system on the rack or the circuit breaker on the chassis. Ventilation The chassis is designed to dissipate 200W per instrument slot. Depending on load, the chassis and power supply fans may exhaust significant heat. Whether used on the benchtop or rackmounted, operate in a well ventilated environment and allow 2” (5 cm) clearance around both sides of the chassis. Do not block the vent holes on the chassis. This overheats and damages components. Leave a gap of at least 2” (50mm) around all vent holes and fan exhaust areas. Rackmounting the Chassis An optional rack mount kit is available from Keysight for each chassis. The kits include mounting instructions. Description of Parts Kit Keysight Part Number 2-Slot Chassis Rackmount Kit Y1225A 5-Slot Chassis Rackmount Kit Y1226A Keysight M9502A/M9505A AXIe Chassis User Guide 29 Chassis Installation Mounting the Chassis Installed Carry Handles and Bumpers Both the 2-slot and 5-slot chassis are shipped with carry handles and bumpers installed for portability and desktop use. For rackmounting, the carry handles and bumpers must first be removed. Tool needed: - #2 Phillips driver for M9502A - #1 and #2 Phillips drivers for M9505A Save all screws, bumpers and carry handles. Reinstall them if you remove the chassis from the rack to make it portable or for desktop use or if you ever need to ship the chassis. If you have been using the chassis with modules and bumpers installed, you should remove all modules (including the ESM) before removing the bumpers. This will make handling the chassis easier and reduce chances of damaging modules. See “To Remove a Module” on page 28. On both the M9502A and M9505A chassis, do not attempt to install the carry handles without the front and rear bumpers. Do not install handle screws without handle and bumpers installed. Handle screws are too long without the other components installed and could result in damage to the chassis. If you remove the chassis from a rack, you should reinstall both the front and rear bumpers and the carry handles To Remove the Carry Handle and Bumpers from the M9502A 1 The 2-slot chassis has a single carry handle, which must be removed before the plastic bumpers. Remove the two #2 Phillips round head screws securing the handle. 2 Remove the two #2 Phillips round head screws from each side of both bumpers (8 screws total) 30 Keysight M9502A/M9505A AXIe Chassis User Guide Mounting the Chassis Chassis Installation 3 Pry the bumpers off the chassis. To Remove the Carry Handles and Bumpers from the M9505A 1 The 5-slot chassis has two carry handles, which must be removed before the plastic bumpers. Remove the two #2 Phillips round head screws securing each handle. 2 Remove the two #2 Phillips round head screws from each side of both bumpers (8 screws total). 3 Remove the three #1 Phillips flat head screws from the top of each bumper (6 screws total). Keysight M9502A/M9505A AXIe Chassis User Guide 31 Chassis Installation Mounting the Chassis 4 Carefully turn the chassis over onto its top. 5 Refer to the photograph on the next page. Remove the four plastic feet from the bottom of each bumper (8 feet total). Each foot is attached to the chassis through the bumper with a small #2 Phillips screw retained at the back of the foot with a plastic washer. Loosen each screw just enough to disengage from the chassis; the foot, screw and washer will remain intact. 32 Keysight M9502A/M9505A AXIe Chassis User Guide Mounting the Chassis Chassis Installation 6 Slide the bumpers off the chassis. Reinstalling the Bumpers and Carry Handles If you remove the chassis from the rack to make it portable or for desktop use or if you ever need to ship the chassis, reinstall the front and rear bumpers and carry handles. Reverse the previous procedures to install the bumpers and handles. A thread-lock screw must be used to secure the handles to the chassis. A new handle screw kit (M9502-80011) is available for use with both chassis. The screws are now 14mm long. Tighten the handle screws to 25kgf.cm (21.8 in-lbs). On both the M9502A and M9505A chassis, do not attempt to install the carry handles without the front and rear bumpers. Do not install handle screws without handle and bumpers installed. Handle screws are too long without the other components installed and could result in damage to the chassis. If you remove the chassis from a rack, you should reinstall both the front and rear bumpers and the carry handles Keysight M9502A/M9505A AXIe Chassis User Guide 33 Chassis Installation Setting Up a Host PC Setting Up a Host PC Following the M9502A/M9505A AXIe Chassis Startup Guide, you should have selected a host PC, made physical connection to the chassis, and communicated with the chassis using its Web Interface. You may have then disconnected the host PC from the chassis in order to install modules or mount the chassis. Re-establish that connection, per the Startup Guide. If you find that your AXIe chassis driver is no longer able to connect, check your host controller’s Network Adapter settings to make certain that the related NIC card has not been disabled. Do not enable the Microsoft Windows sleep mode on the host PC. The PC may not have proper chassis enumeration when it wakes up and unpredictable operation may result. To Install Module Soft Front Panel and Device Drivers Each installed module typically requires device drivers and control software. You need not install them to verify basic chassis operation, but would logically install them on the host PC at this time. For Keysight instrument modules, load each module’s Software and Product Information CD into the optical drive of your PC and follow the prompts. For others, consult the module provider for software requirements and instructions. 34 Keysight M9502A/M9505A AXIe Chassis User Guide Verifying Operation with Modules Installed Chassis Installation Verifying Operation with Modules Installed In the M9502A/M9505A AXIe Chassis Startup Guide, you should have verified basic power-on operation of the AXIe chassis and communication with the host PC. Subsequently, in this chapter you have installed instrument modules and perhaps rackmounted the chassis. Then you have reconnected the host PC, and loaded chassis and module software drivers. Reverify that Connection Expert communicates with the chassis and installed modules. The LAN connection to the ESM provides communication to the chassis only -chassis firmware updates, web interface to monitor/control the chassis, etc. It does not provide communication with individual AXIe modules. Use PCIe to control AXIe modules. - Power up the chassis (solid green status light on the ESM). - Reboot the host PC. This allows the host PC’s BIOS to recognize the PCIe devices in the chassis. - You may need to run the appropriate Add Hardware process in Windows for the host PC’s operating system to correctly recognize and enumerate modules on the PCIe bus. - Establish chassis communication with Keysight Connection Expert. - Keysight Connection Expert should recognize installed modules, and they should be listed on the chassis Web Interface Module Configuration Page. - After driver installation is complete, restart your PC. The Ethernet Controller Found New Hard ware Dialog should no longer appear. Keysight M9502A/M9505A AXIe Chassis User Guide 35 Chassis Installation Using the M9536A Embedded Controller LAN Ports Using the M9536A Embedded Controller LAN Ports If you installed a Keysight M9536A Embedded Controller in the Keysight AXIe chassis (M9502A or M9505A), there are a total of three LAN ports accessible on the front panels -- two on the M9536A controller and one on the Embedded System Module (ESM). Windows Device Manager shows a total of five (5) individual Network Interface Cards (NICs); one is not used and one connects to the chassis backplane. Changing the LAN port connection or removing the LAN cable, may cause Keysight Connection Expert to lose track of LAN-enabled instruments. Reboot the AXIe chassis to restore the complete list of LAN-enabled instruments. Read the following for details. Figure 1 NIC ports reported for the M9536A (NIC 3 is not used) NIC numbers correspond to the numbering in Figure 1 above. Note that NIC 3 is not used. NIC numbering on your controller may be different. Figure 2 36 Windows Device Manager showing Network Connections Keysight M9502A/M9505A AXIe Chassis User Guide Using the M9536A Embedded Controller LAN Ports Chassis Installation This section provides overall guidance on selecting and using the M9536A LAN ports. The controller uses the Keysight IO Libraries configuration file to keep track of all instrument connections. Any change to LAN connections after running Connection Expert (adding, removing, or changing LAN cable connections) may cause a change in LAN address and therefore cause Connection Expert to lose track of instruments. If your application programs rely on a specific IP address, these programs may cease to operate if you change LAN cable connections. Changes to the ESM PCIe or LAN connection are only detected as the ESM is powered up. Perform the following steps when you change either of these two connections: 1 Within Keysight Connection Expert, delete the LAN interfaces (right click on the interface then select Delete). This causes Connection Expert to forget all instrument history. 2 Shut down Windows on the M9536A Embedded Controller. 3 After Windows shuts down, power down the AXIe chassis using the chassis power button. 4 Make the desired cabling change to the ESM PCIe and/or LAN connections. 5 Power up the AXIe chassis using the chassis power button. 6 Run Keysight Connection Expert and verify that the LAN interfaces are operating correctly and that Connection Expert finds the AXIe chassis. With Keysight IO Libraries 16.2 (and later versions) Keysight Connection Expert should automatically identify the AXIe chassis. With Keysight IO Libraries version 16.1, you may need to start Connection Expert, then power down the controller and chassis and reboot them in order for Connection Expert to identify the AXIe chassis. Recommendations As a general rule, connect a network LAN cable to the ESM’s LAN port and connect LXI instruments to the M9536A’s LAN ports. While other configurations are viable, this configuration provides the fastest and most consistent reporting in Keysight Connection Expert. Refer to Figure 3. - Where you have the network and instruments connected when the chassis and controller first power on determines how quickly Keysight Connection Expert locates network instruments. If necessary, shut down the controller and chassis and reboot. - If you move a LAN cable while chassis power is applied, Connection Expert may not find all of the instruments available on the network. Keysight M9502A/M9505A AXIe Chassis User Guide 37 Chassis Installation Using the M9536A Embedded Controller LAN Ports For example, if the LAN cable is connected to the ESM when power is first applied to the chassis and subsequently moved to one of the two LAN ports on the controller (while the chassis is still powered on), Connection Expert may only find the M9536A controller and AXIe modules installed in the chassis. Shut down the controller and chassis and reboot to restore Connection Expert’s ability to locate other network instruments. - Connect external LAN-enabled instruments (LXI instruments) to the M9536A controller LAN ports. This allows Keysight Connection Expert to automatically find the instruments. These instruments will have a local LAN IP address or private network range. LXI instruments may be connected to the ESM’s LAN port but Connection Expert may not automatically find them when these instruments are not located on the same LAN subnet range. However, instruments may be added manually using Connection Expert’s Add Address feature. - If you are using an external LAN router or switch, cycling power on the chassis may cause the IP address of the chassis ESM and controller to change. Therefore you may want to set a static IP address. Refer to your particular network device’s documentation for information on setting static IP addresses. With the Keysight M9536A Embedded Controller installed in the AXIe chassis, the x8 PCIe connection on the ESM module is disabled. However, the PCIe cable detect mechanism may reset the hardware when attaching a PCIe cable. This hardware reset may change the IP address. 38 Keysight M9502A/M9505A AXIe Chassis User Guide Using the M9536A Embedded Controller LAN Ports Figure 3 Chassis Installation Recommended LAN Connections The above figure shows the recommended LAN connections to the AXIe chassis/ESM and the M9535A. Two other possible LAN connections are shown in the following figure. Note that you may need to manually add instrument IPO addresses to Keysight Connection Expert. Keysight M9502A/M9505A AXIe Chassis User Guide 39 Chassis Installation Figure 4 40 Using the M9536A Embedded Controller LAN Ports Possible Alternate LAN Connections. You may need to manually add instrument IP addresses to Keysight Connection Expert. (see text) Keysight M9502A/M9505A AXIe Chassis User Guide Using an external controller Chassis Installation Using an external controller Changes to the ESM PCIe or LAN connection are only detected as the ESM is powered up. Perform the following steps when you change either of these two connections: 1 Within Keysight Connection Expert, delete the LAN interfaces (right click on the interface then select Delete). This causes connection Expert to forget all instrument history. 2 Turn off the remote host controller. 3 Power down the AXIe chassis using the chassis power button. 4 Make the desired cabling change to the ESM PCIe and/or LAN connections. 5 Power up the AXIe chassis. 6 Power on the remote host controller. 7 Run Keysight Connection Expert and verify that the LAN interfaces are operating correctly and that Connection Expert finds the AXIe chassis. Keysight M9502A/M9505A AXIe Chassis User Guide 41 Chassis Installation Using Multiple Chassis Using Multiple Chassis There are several possible ways to configure multiple M9502A 2-Slot and M9505A 5-Slot AXIe chassis systems. You can also combine AXIe and PXIe chassis (such as the M9018A PXIe chassis) into multiple chassis configurations. These multiple chassis configurations are controlled by a single host controller. The host controller can be either a PXIe Embedded Controller (such as the Keysight M9036A) or a desktop or rack-mounted computer. For detailed configuration and installation information, refer to Keysight's Multiple PXIe and AXIe Chassis Configuration tool. This tool is available on the M9502A/M9505A Product information CD and on line at: or www.keysight.com/find/M9502A www.keysight.com/find/M9505A How does a multiple chassis system differ from a MultiFrame system? In both multiple chassis and MultiFrame systems, all chassis are controlled by a single controller. The differences between the two system types are: – In a multiple chassis system, the time base and triggering for each chassis operates independently from the other chassis. You can use this type of configuration to increase the number of chassis/modules that do not require a common time base or cross triggering between chassis. For more information, refer to Keysight's Multiple PXIe and AXIe Chassis Configuration tool. This tool is available on the M9018A Product information CD and on line at: www.keysight.com/find/pxie-multichassis. – MultiFrame is a Keysight feature by which multiple instruments in two or more chassis are interconnected to appear as one integral instrument to the user. In a MultiFrame system, special cabling connects the time base and triggering of the master chassis to all daisy-chained slave chassis. These cables extend trigger and timing features to instruments not connected to the master chassis’s backplane. You can use the MultiFrame configuration to increase the number of measurement modules utilizing a common time base or cross triggering. Refer to “MultiFrame Operation” on page 89 for more information. 42 Keysight M9502A/M9505A AXIe Chassis User Guide M9502A/M9505A AXIe Chassis User Guide 3 Navigating the Web Interface This chapter provides a complete overview of the AXIe chassis Web Interface, which allows for chassis monitoring and configuration. The Web Interface is stored in the chassis firmware, and may evolve in look and functionality as more recent versions of the firmware are developed. The examples in this manual reflect the firmware at time of product introduction. Launching the Web Interface 43 Home Page 44 Menu 45 LAN Configuration Page 46 Module Configuration Page 47 Trigger Routing Page 51 Chassis Health Page 53 Configure Fan Control 54 The LAN connection to the ESM provides communication to the chassis only -chassis firmware updates, using the web interface to monitor and control the chassis, etc. It does not provide communication with individual AXIe modules. Use the PCIe connection to control individual AXIe modules. Launching the Web Interface The M9502A/M9505A Startup Guide provides detailed instructions for connecting to the chassis using Keysight Connection Expert and launching the Chassis Web Interface. Following those instructions, launch the Web Interface. If you have problems launching the chassis Web interface, check your browser’s proxy settings. When Keysight Connection Expert launches a Web interface for a chassis, it hands off the http://<address> to the browser or dedicated web application. Therefore, it should not use a proxy. 43 Navigating the Web Interface Home Page Home Page The home page displays identifying information about your chassis and LAN connection, more if you click the Advanced Information ( ) button. Chassis Firmware Version (see page 110) Clicking Turn On Front Panel Identification Indicator will cause the ESM front panel STATUS light to flash steadily; use this to quickly identify which chassis you are communicating with. 44 Keysight M9502A/M9505A AXIe Chassis User Guide Menu Navigating the Web Interface Menu The six buttons at left are the Web Interface’s Menu: Home Page - General Information about the chassis, such as product identification, firmware version and LAN parameters, LAN Configuration Page - Display IP address, domain, and subnet, service discovery information, and LAN status.

Keysight M9502A/M9505A AXIe Chassis User Guide 45 Navigating the Web Interface LAN Configuration Page LAN Configuration Page Click the button to display the LAN Configuration page: Initial releases of the AXIe chassis will have IP configuration set to Automatic; the IP Address, Subnet Mask and Default Gateway are set automatically and cannot be changed. When you make a LAN connection between host PC and chassis ESM, and then power-on the chassis, the following process happens: 1 The chassis, as client, seeks a Dynamic Host Configuration Protocol (DHCP) server to set the IP configuration. 2 If you connected the chassis and PC to a corporate LAN, the network will provide the DHCP addresses. 3 If you made a direct LAN connection (physical LAN or implicit LAN connection through PCIe), the chassis reverts to link-local addressing. If you are having difficulty ‘finding’ a specific AXIe chassis on a network, you can search by the mDns Instrument Name, which includes the unique chassis serial number. This number is located at the rear of the chassis. 46 Keysight M9502A/M9505A AXIe Chassis User Guide Module Configuration Page Navigating the Web Interface Module Configuration Page Click the button to display the Module Configuration page. This page allows you to view the physical location and identifying information for recognized modules installed in the chassis, as well as the chassis frame and Embedded System Module. Note PCIe mode; either PCIe Upstream Connection Settings, see The above example shows an M9505A chassis with two installed modules (slots 3 and 4) and the Keysight M9536A Embedded Controller in slot 1. Keysight M9502A/M9505A AXIe Chassis User Guide 47 Navigating the Web Interface Module Configuration Page ESM PCIe Upstream Connection Settings The section for the ESM PCIe Upstream Connection displays the current PCIe configuration (called the Active Configuration) and allows you to change the configuration if necessary. You should seldom need to change the PCIe Upstream Configuration. Leave it set to Auto for the ESM to select the appropriate configuration. New Configuration The New Configuration field allows you to designate a PCIe Upstream Connection or designate an enumeration wait time. As a general rule, you should not need to reconfigure these; you should leave the PCIe Upstream Configuration in Auto mode. If you do select a new PCIe Configuration and/or enumeration wait time, you must click the Apply New PCIe Settings button to save the changes as the new default. The changes take effect after cycling power on the chassis. To restore the factory default setting, click the Restore Factory Defaul t button. PCIe Upstream Configuration: The possible PCIe Upstream Connections are: - Auto: The ESM automatically determines the upstream connection port. This is the default setting. - PCIe Front Panel: The PCIe upstream connection port is the ESM PCIe connector. - USB Front Panel: The PCIe upstream connection port is the USB PCIe connector. This option is available only if the Option U20 USB ESM is installed. See “AXIe Embedded System Module (ESM) Option U20 with USB” on page 9 - Slot 1 (Instrument Hub): An embedded controller (such as the Keysight M9536A) can act as a PCIe root complex when installed in slot 1 of the chassis. This is also known as the “Instrument Hub.” Depending on your chassis configuration (ESM, embedded controller, etc.) some of the upstream connections may not appear in the pull-down menu. Wait Time: You should not need to change the enumeration wait time. However, some AXIe instrument modules (also known as Blades) take longer to be ready for enumeration than the PXI link ready requirement of 100ms. Consequently, it is possible for some controllers (such as the Keysight M9536A Embedded Controller) to enumerate the chassis before all of the individual modules are ready and therefore not enumerate them. If you have a situation where Keysight Connection Expert and/or the Windows Device Manager consistently do not find specific instrument modules when the chassis powers up, increase the wait time (valid range is 0 to 60 seconds). 48 Keysight M9502A/M9505A AXIe Chassis User Guide Module Configuration Page Navigating the Web Interface E-Keying Scrolling down the Module Configuration page displays the E-Keying Activity information. E-Keying (short for Electronic Keying) is a process in which compatible matches over links between different modules are identified and enabled to be used. For more information on E-Keying refer to “Electronic Keying (E-Keying)” on page 92. In general, you do not need to understand how E-Keying works. The E-Keying process is handled by the chassis shelf manager. The following two figures illustrate the Module E-Keying Activity display in the Module Configuration Page. In the following segment, note that modules in Slots 3 and 4 (column 1 “From Slot” and column 2 “To Slot”) have an Enabled status and use the AXIe Local Bus (62 pair Local Bus). This simply states that the Shelf Manager has given the two modules permission to communicate directly (E-Keying) over the AXIe backplane local bus. Also note that both modules are enabled to use the AXIe Timing STRIG link and the PCI Express fabric. Keysight M9502A/M9505A AXIe Chassis User Guide 49 Navigating the Web Interface Module Configuration Page More information on AXIe E-Keying is available on the AXIe Consortium website: www.axiestandard.org. 50 Keysight M9502A/M9505A AXIe Chassis User Guide Trigger Routing Page Navigating the Web Interface Trigger Routing Page Click the button to display the Trigger Routing page. This page allows you to view and assign static trigger routing through the ESM, using the chassis Crosspoint Switch. Trigger Routing on your M9505A AXIe 5 Slot Chassis This page allows control of trigger routing connections through the crosspoint switch between the chassis backplane and external connections located on the the Embedded System Module (ESM). These connections may be applied, saved as a default configuration, and later restored if necessary. For more detailed information on the trigger subsystem, see the M9502A/M9505A AXIe Chassis User's Guide. Please note this page does not control signal routing on module slots.

You can choose to enable and assign the input source for any or all signal destinations (trigger/timing resources to be output from the ESM). You can also source a logical 0 or 1 to drive any output for test purposes. Multiple outputs may be driven from the same input, but each output can have only one input assigned. The default input for all outputs is “Static 0”, which assigns a logic 0. These trigger bus inputs and outputs are covered in detail in “Triggering” beginning on page 78. Making Trigger Routing Changes The Trigger Routing page provides several buttons at the bottom of the form, which allow you to apply, save, and restore trigger bus States, complete sets of trigger bus configuration settings. These States are stored in non-volatile RAM (NVRAM); settings do not change when you cycle power to the chassis. Trigger bus settings displayed in the Trigger Routing page form are not activated until you apply them. Active State: Each time you load or refresh the Trigger Routing page, it shows the Active State (of the trigger bus). - The displayed form allows you to make and display configuration changes, but they are not made Active until you specifically apply them. - If you click the Apply Changes button, the displayed settings will be made Active (become the Active State). - If you do not want to apply the displayed changes, do not click Apply Changes. You can click Clear Form to clear all trigger bus assignments on the form. - If you want to restore the Active State, click the Discard and Refresh button. Default State: The chassis will store a custom set of default settings, called the Default State. - If you click the Save as Default button, the displayed settings will be made Active and be saved as the new Default State. - You can always restore the form to the Default State by clicking the Restore Form from Default button. Then, if you click the Apply Changes button, the Default State will be made Active. Factory Default State: You can always restore the form to the factory default, by clicking the Restore Factory Default button. Then, if you click the Apply Changes button; the factory default becomes the Active State. Complete description, selection and routing instructions for the trigger bus are provided in “Chassis Synchronization and Triggering”, beginning on page 75. 52 Keysight M9502A/M9505A AXIe Chassis User Guide Chassis Health Page Navigating the Web Interface Chassis Health Page Click the button to display the Chassis Health page. Note that, in the example below, three fan speeds are shown as below the minimum fan speed limit. . Keysight M9502A/M9505A AXIe Chassis User Guide 53 Navigating the Web Interface Chassis Health Page This page has three sections: Sensors, Fan Control and Chassis Firmware Upgrade. Sensor monitoring is explained in detail in “Shelf Management Functions” on page 68. To update the chassis firmware, see “Updating the Chassis Firmware” on page 110. Configure Fan Control The minimum chassis fan speed is approximately 2200 RPM; the maximum fan speed is approximately 6000 RPM. Using a range of 35 to 100 (percentage of maximum), you can manually set the minimum speed you want the fans to operate at — 35 means the minimum fan speed of approximately 2200 RPM and 100 is the maximum fan speed of approximately 6000 RPM. Each increment is approximately 58 RPM. Do not attempt to set the fan speed below 35. Earlier chassis firmware versions (see AXIe Chassis Version Information below), used fan speed numbers from 8 to 15, with 8 representing the minimum fan speed and 15 representing the maximum fan speed. For backwards compatibility, these numbers are now reserved. If you have an existing application program using IVI or LabVIEW drivers to set the minimum fan speed using the old 8 to 15 range, your program will continue to work normally with the new AXIe chassis firmware; 8 now corresponds to the new 35 (minimum fan speed) and 15 corresponds to the new 100 (or maximum fan speed). The new firmware revision returns fan speed as 35 to 100. If your application program reads the current fan speed and expects a value between 8 and 15, your program may error. Please adjust your application appropriately. Regardless of where you set the minimum fan speed, if the temperature inside the AXIe chassis rises, the fans speed increases to provide additional cooling. The resolution of the Current Fan Level, as shown on the Chassis Health interface page, is an approximation of the fan speed. The Configure Fan Control section of the Chassis Health Page has the following 5 fields: Fan Status The shelf manager continuously monitors chassis fan speed, looking for indication that one or more fans are not turning. Normal fan status represents a fan speed of at least 2200 RPM (or higher when required by instrumentation load). Below that speed, the shelf manager reports an alarm condition for that fan, it attempts to increase fan speed and continues to monitor. Failure of one fan will not result in interruption of power to installed modules. 54 Keysight M9502A/M9505A AXIe Chassis User Guide Chassis Health Page Navigating the Web Interface Cooling Status The shelf manager continuously monitors reported module temperatures, looking for indication that one or more modules is outside its optimal temperature range. This range is specified by the module vendor, as are the thresholds for alarm conditions. Typically only high temperatures generate an alarm, although it is possible for a vendor to specify low temperature alarm levels as well. In the event of a high temperature alarm from any module, the shelf manager responds by increasing chassis fan speed and continuing to monitor. If the Upper Non-Recoverable threshold is reached, the shelf manager requests the module to power down to its inactive state. Because this level is set by the module vendor, it may not indicate that the module has failed, only that continued operation is inadvisable until the module cools. Current Speed Level This is the level the fans are currently operating and is controlled by the Shelf Manager. It increases from a set minimum as needed to adjust for changes in chassis temperature. The range is from 35 to 100, where 35 is the slowest speed level and 100 is the highest speed level. The Current Speed Level indicates an approximate percentage of maximum fan RPM. Therefore, a level of 40 indicates the fans are operating at approximately 40% of maximum RPM, and 100 indicates the fans are operating at 100% of maximum RPM. Note, the default/reset value is 40. Dynamic Minimum Fan Level This is the minimum fan level the shelf manager algorithm sets as it actively monitors the overall system temperature and temperature threshold events received from instrument modules. Over time, the algorithm adjusts this level towards the user-specified minimum fan level provided the cooling status remains at Normal. Adjust Current Speed Level and Dynamic Minimum Fan Level This user adjustable parameter actually sets both values. This level is kept in non-volatile RAM until you change it; cycling power to the chassis does not change the minimum fan level. Adjust the minimum fan level by entering a value in the field, or clicking the up/down arrows, and then clicking the Apply button. Note that you can individually set the Current Speed Level and the Dynamic Minimum Fan Level using ICI controls. The Web UI (and the Soft Front Panel) binds these two together. Setting the Current Speed Level is always temporary because the Dynamic Minimum Fan Level algorithm continuously adjusts the fan speed towards a dynamic minimum when cooling conditions permit. For example, consider a situation where the chassis and installed modules require a fan speed of 50 to maintain proper cooling. If you attempt to manually set the Current Fan Speed to a lower value (40 for example) the algorithm overrides the setting and maintains the fan speed to provide adequate cooling. Conversely, if you manually set the fan speed to a higher value (65 for example), the algorithm sets that fan speed and does not change it unless additional cooling becomes required. Keysight M9502A/M9505A AXIe Chassis User Guide 55 Navigating the Web Interface Chassis Health Page Of course, since the actual cooling requirements for the chassis and modules may continuously change, that actual fan Current Speed Level and the Dynamic Minimum Fan Speed will also change over time. Example of Chassis Fan Speed The following graph illustrates how the chassis fan speed operates. For simplicity, only one temperature event is shown; in reality, temperature events may be happening frequently causing the fan Current Speed Level to change and the Dynamic Minimum Fan Speed to gradually change. Assume at the beginning, the chassis is reporting a Nominal cooling status. The Dynamic Minimum Fan Level is approximately the same as the fan Current Speed Level. When one (or more) temperature sensors reports that a temperature has increased above its Nominal range and is now above its Upper Non-Critical threshold, a Minor Alert occurs on the cooling status. At this point, the chassis fan Current Speed Level begins ramping up to provide additional cooling. Note that the change is not instantaneous. When the temperature sensors report that the temperature has dropped back into the Nominal range (because of hysteresis it is actually a few degrees below the Upper Non-Critical threshold), the chassis fan Current Speed Level begins to gradually slow down, compensating for the reduced heat load. 56 Keysight M9502A/M9505A AXIe Chassis User Guide Chassis Health Page Navigating the Web Interface During this entire time, the Dynamic Minimum Fan Level algorithm is recalculating to provide a new minimum fan speed. As additional temperature events occur, and the Current Fan Level changes, the Dynamic Minimum Fan Level algorithm recalculates the minimum fan speed required to ensure optimal cooling in the chassis. AXIe Chassis Version Information and Fan Speed AXIe Chassis Firmware version IVI Driver version Fan Speed Range 1.3.8 (actually, 1.3.08) 1.1.1.1 8 (minimum) to 15 (maximum) 1.3.23 1.1.1.1 Chassis firmware, including the Chassis Web Interface page uses 35 to 100. However, the IVI and LabVIEW drivers, including the Soft Front Panel interface, had not been updated to use the 35 to 100 range. 1.3.23 (and later) 1.2.0.x (and later) Chassis firmware and the IVI and LabVIEW drivers, including the Soft Front Panel interface, were updated to use the 35 to 100 range.

The SFP provides the same functionality as the Web Interface. While the Web Interface runs in a browser window and accesses the web server built into the chassis, the SFP is an executable which runs on a PC and communicates to the chassis using the IVI drivers. The SFP is installed automatically when the chassis software is installed. Starting the Soft Front Panel SFP Screens 61 60 59 Using the Soft Front Panel Starting the Soft Front Panel Starting the Soft Front Panel After the chassis software is installed, the SFP can be started from the Start menu as follows: Start > All Programs > Keysight > M950x AXIe Chassis > M950x SFP The SFP help system can be launched from the Start menu as well. For detailed information on the features and functionality of the SFP, see the SFP help system. IMPORTANT: If your chassis is connected to the host PC via a LAN connection, and Keysight Connection Expert has discovered the chassis as a LAN device, then the Soft Front Panel software will also find the chassis. However, if you connected the chassis to the host PC via PCIe cable, you must manually add the chassis to the LAN device tree. This is true, even if Keysight Connection Expert has found the chassis and listed it under the PXI device tree. To add the chassis as a LAN device, select the LAN tree, then select Add Instrument. The chassis must be added as Socket protocol (typically port 5025). 60 Keysight M9502A/M9505A AXIe Chassis User Guide SFP Screens Using the Soft Front Panel SFP Screens The SFP contains two screens, the Monitor screen and the Configure Trigger Routing Screen. Monitor screen The Monitor screen is used to monitor the chassis fan speeds, the temperature sensors, and the chassis voltages. The following graphic shows an M9502A 2-slot chassis with a module in slot 1 that has both Temperature and Voltage sensors. Configure Trigger Routing The Configure Trigger Routing screen is used to configure the inputs and outputs of the chassis Crosspoint Switch.

The just-saved configuration is re-applied using the Restore from Default State button. Only one state can be saved. – Restore from Defaul t State: This button restores the trigger subsystem to the power-on default configuration. The power-on default configuration can be a previous configuration saved by using the Save as Default State button. Otherwise, the power-on default configuration is the factory default configuration. In the Simulation Mode, the Save as Default State button does not actually save the configuration. The Restore from Default State always restores the Factory Default configuration. The state is saved in the chassis hardware, hence, in Simulation Mode, there is no ability to save or recall states.

Therefore, the AXIe chassis, when accessed over PCIe, will be displayed as a LAN device in Connection Expert as shown above. PCIe modules, however, will be displayed under PXIO and will be able to use the full bandwidth of the PCIe interface. 3. The PCIe Switch internal buffering allows the chassis to communicate to the host PC at 4 GB/s, and simultaneously communicate at 2 GB/s to each of two x4 module slots. Factoring in certain overheads, nominal data rates of 1.85 GB/s per slot can be achieved. 2. PCIe Generation ((“Gen”)) 1 peak speed is 2.5 Gb/s per lane. PCIe Gen 2 peak speed is 5.0 Gb/s per lane.

Shelf management is implemented in the ESM firmware. You may upgrade firmware through the base interface (LAN) connection. To Monitor Fans: You can check the individual chassis fan speeds, fan levels, and status. The fan speeds are listed under the Chassis header in the Sensors section of the Chassis Health page. 68 Keysight M9502A/M9505A AXIe Chassis User Guide Shelf Management Functions Features and Functions Under Fan Control, you can monitor Fan Status, Cooling Status, Present Fan Level, and Minimum Fan Level. These are explained in order below. Fan Status: The shelf manager continuously monitors chassis fan speed, looking for possible indication that one or more fans are not turning. Nominal fan status represents a fan speed of approximately 2,000 RPM, higher when required by instrumentation load. Below that range, the shelf manager will report an alarm condition for that fan, attempt to increase fan speed and continue to monitor. Failure of one fan will not result in interruption of power to installed modules. The fan status conditions are listed below. Fan Status Fan Speed (RPM) Shel f Manager Response Nominal 2,000 or higher Continue monitoring fan speed Lower Non-Critical Increase fan speed one step and continue monitoring Lower Critical Increase fan speed to maximum and continue monitoring Lower Non-Recoverable This usually indicates a fan has stopped turning; increase fan speed to maximum and continue monitoring Cooling Status: The shelf manager continuously monitors reported module temperatures, looking for indication that one or more modules is outside its optimal temperature range. This range is specified by the module vendor, as are the thresholds for alarm conditions. Typically only high temperatures generate an alarm, although it is possible for a vendor to specify low temperature alarm levels as well. In the event of a high temperature alarm from any module, the shelf manager will respond by increasing chassis fan speed and continuing to monitor. If the Upper Non-Recoverable level is reached, the shelf manager will shut down power to that module. As this level is set by the module vendor, it may not indicate that the module has failed, only that continued operation is inadvisable until the module cools. Cooling Status Nominal Upper Non-Critical Upper Critical Upper Non-Recoverable Module Temp Shel f Manager Response specified by module vendor Continue monitoring module temperature Increase fan speed one step and continue monitoring Increase fan speed to maximum and continue monitoring Increase fan speed to maximum, deactivate that module and continue monitoring. This usually implies imminent module damage if operation continues; Keysight M9502A/M9505A AXIe Chassis User Guide 69 Features and Functions Shelf Management Functions Current Speed Level This is the level the fans are currently operating at and is controlled by the Shelf Manager. It increases from a set minimum as needed to adjust for changes in chassis temperature. The range is from 35 to 100, where 35 is the slowest speed level and 100 is the highest speed level. The speed level indicates an approximate percentage of maximum fan RPM. Therefore, a level of 40 indicates the fans are operating at 40% of maximum RPM, and 100 indicates the fans are operating at 100% of maximum RPM. Dynamic Minimum Fan Level This is the minimum fan level the shelf manager algorithm sets as it actively monitors the overall system temperature and temperature threshold events received from instrument modules. Over time, the algorithm adjusts this level towards the user-specified minimum fan level provided the cooling status remains at normal. Adjust Current Speed Level and Dynamic Minimum Fan Level This is a user adjustable parameter allowing you to specify a minimum fan speed level. This level is kept in non-volatile RAM until you change it; cycling power to the chassis does not change the minimum fan level. Adjust the minimum fan level by entering a value, or clicking the up/down arrows and clicking the Apply button. You cannot monitor the PSU fans. To Control Fan Speed: You can set the minimum fan level, over a range from 35 to 100 as a percentage of maximum fan speed, by setting that level in the Adjust Current Speed Level and Dynamic Minimum Fan Level field and clicking the Apply button. This specifies the minimum level at which you want the chassis fans to run. The Shelf Manager will increase fan speed from that minimum—for all (three or six) chassis fans—if required by an alarm condition (low fan speed or high module temperature). If the minimum fan speed is changed using the Web Interface, the newly-set value will become the chassis power-on default value. This is unlike other parameters set using the Web Interface, which do not persist through a power cycle. For more detailed information on controlling the fans using the Web Interface, refer to “Configure Fan Control” on page 54. The power supply (PSU) fans are controlled automatically, you cannot override them. 70 Keysight M9502A/M9505A AXIe Chassis User Guide Shelf Management Functions Features and Functions To Monitor Chassis Temperature: There are two backplane sensors which measure chassis temperature in degrees celsius. These temperatures are listed in the Sensors section of the Chassis Health page. They are provided as an indication of ambient chassis temperature only; the individual slot temperatures reported by installed modules control the chassis fans. To Monitor Module Health: The Sensors section of the Chassis Health page lists sensor measurements for each module slot. The sensors are vendor-specific, and the type of readings will vary by module. Below is a screen capture of the Sensors section from a chassis with two modules installed.

PCIe: This is the high speed primary data path: - From the PCIe switch in the ESM—the fabric 1 hub—four lanes to each instrument slot through the backplane defined as PCIe x4. - From the PCIe switch in the ESM to the PCIe x8 front panel connection. Fabric 2: Fabric 2, if implemented, provides a high speed secondary data path through the backplane: - From an instrument hub module in slot 1—the fabric 2 hub—four lanes to each instrument slot through the backplane; protocol is vendor-defined. - Fabric 2 data does not pass through the ESM; you must make external connections to the instrument hub to use fabric 2 data Keysight M9502A/M9505A AXIe Chassis User Guide 73 Features and Functions PCIe and LAN Switching (data transfer) Implementing Fabric 2 To use fabric 2, the secondary data path (four channels) through the chassis backplane, you must: - Install in slot 1 an AXIe instrument hub module designed to implement the fabric 2 star. Access to these backplane signals must be controlled by the instrument hub module. - Use a remote host PC. With an instrument hub module, you cannot simultaneously use an embedded controller, which must be installed in slot 1. Maximizing Data Upload Speeds The maximum data bandwidth to each slot is dictated by the x4 connection. You will typically achieve higher PCIe data throughput to a remote (desktop or rackmount) host PC than to an embedded controller. - Using a high speed rackmount or desktop PC and a x8 cable, the primary data fabric utilizes a x8 connection between the ESM and the host PC. The ESM’s PCIe switch can achieve Gen2 upload speeds when transferring data to the host from multiple modules simultaneously. - If an embedded controller is installed in the chassis, that x8 connection is disabled; the controller uses its slot 1 backplane x4 link to the PCIe switch. - By using both an instrument hub module and a fast remote host PC with dual x8 cable adapters, you could potentially move two x8 fabric channels to the host at Gen 2 speeds (if the instrument hub outputs PCIe x8). PCIe, LAN or Both? You can establish communication between the chassis and host PC over either a LAN or a PCIe connection. In practice, the choice is usually driven by the interface(s) on your modules. For example, if you have a module with a x4 PCIe interface, you’ll want to establish a PCIe connection to the chassis. PCIe Connection Only You may connect the ESM to the host PC using only a PCIe cable. This allows both the base (LAN) channel and fabric 1 data channels. Base channel communication between PC, ESM and any LAN capable installed instruments are made through the PCIe connection. A PCIe to LAN switch in the ESM manages the base channel communication to the slots; it is seen as a network interface device by Windows Device Manager. LAN Connection Only You may connect ESM to host PC using only a LAN cable. You will have base channel communication only and significantly less data throughput that when using PCIe. Hybrid Operation: You may connect both LAN and PCIe cables from ESM to host PC. This provides the most operational flexibility and some data throughput advantages over using only PCIe. 74 Keysight M9502A/M9505A AXIe Chassis User Guide Chassis Synchronization and Triggering Features and Functions Chassis Synchronization and Triggering The Keysight AXIe chassis provides a rich set of signaling (triggering and timing) options. These allow you to achieve time-aligned operation of multiple instruments installed in a single chassis or MultiFrame (interconnected AXIe chassis system). MultiFrame operation is described in “MultiFrame Operation” on page 89. For this chapter, ‘instruments in the chassis’ includes all instrument modules in the single chassis or MultiFrame. If you are using only a single chassis, the MultiFrame references are inapplicable. An example of time aligned operation would be starting and stopping some aspect of a test running on multiple instruments in the chassis. The time alignment of these operations can be: - Synchronous: A single event (trigger signal or sync signal), initiated by an external trigger, flag, or other signal transition, triggers one or more instruments simultaneously. - Asynchronous: Instruments operate independently, with their resulting data to be time-aligned post-collection in your analysis software. This requires the data to be referenced to a common clock source. Moreover, there is capability to group instruments and perform such operations on several independent groups simultaneously. For example, instrument group A can be triggered from a 100MHz clock and instrument group B can receive an external trigger from an event transition in the test environment, while receiving the same clock signal to synchronize the two groups. Although the triggering and timing options can be inter-operated, it is easiest to understand them using distinct Clock Bus and Trigger Bus diagrams, each providing ESM front panel and backplane signal connections. Some AXIe test system software applications, such as the Keysight AXIe Based Logic Analyzer Software and modules, sets and uses specific trigger lines in the AXIe chassis. Do not use the AXIe chassis Soft Front Panel (SFP) software or the AXIe chassis web interface to set or reroute any of the AXIe chassis trigger lines. Rerouting any of the trigger lines may cause the application software to not function correctly. Keysight M9502A/M9505A AXIe Chassis User Guide 75 Features and Functions Chassis Synchronization and Triggering Synchronization Available Clocks Clock Outputs The Embedded System Module (ESM) generates a 100 MHz instrument clock signal from its clock bus. This signal is: - Star distributed to all instrument slots as CLK100 - Provided to the ESM’s front panel SMA connector CLOCK OUT, as a 10 MHz external reference clock (3.3V CMOS, 50W) - Distributed to additional chassis as MULTIFRAME OUTPUT CLK100 A separate 100 MHz distributed PCIe fabric reference clock (FCLK) is provided from the ESM to all instrument slots. Clock Sources There are three possible sources for the clock bus in a given chassis. Clock detection logic is automatic, and the input source is chosen in the following priority order, depending on which external inputs are sensed: 1 An external reference clock (MULTIFRAME INPUT CLK100) from the lower chassis connector 2 A 10 MHz external reference clock (CLOCK IN) applied at the ESM’s front panel SMA connector If you choose the external 10 MHz reference clock, it must be present at the front panel SMA connector when the chassis is powered on. If you attach the cable after power is applied, you must cycle power on the chassis. 3 The local 100 MHz clock oscillator within the ESM Clock Bus Diagram The clock resources are illustrated below.

FCLK [5] PLL /10 Keysight M9502A/M9505A AXIe Chassis User Guide Chassis Synchronization and Triggering Features and Functions Selecting a Clock Bus Source By default, the clock bus is driven by the local 100 MHz clock oscillator. You can also drive the clock bus from an external reference clock supplied by CLOCK IN or the MultiFrame Cable. To use CLOCK IN: You can connect a 10 MHz external reference clock source to drive the clock bus on any given chassis. 1 Provide a clock source at that chassis’s front panel SMA connector. The chassis will recognize a signal with these characteristics: – AC coupled, -5V to +5V input – 250 mV minimum swing – frequency 10 MHz ±5% 2 The chassis will automatically select CLOCK IN if sensed. When a chassis senses both CLOCK IN and MULTIFRAME INPUT CLK100, MULTIFRAME INPUT CLK100 has priority. If you choose the external 10 MHz reference clock, it must be present at the front panel SMA connector when the chassis is powered on. If you attach the cable after power is applied, you must cycle power on the chassis. To use MultiFrame INPUT CLK100: In a MultiFrame system, the CLK100 signal sourced from the master chassis drives the clock buses for all slave chassis. 1 The CLK100 signal is provided from the master to each slave chassis’s MULTIFRAME INPUT (lower chassis) connector. 2 Each slave chassis will automatically select MULTIFRAME INPUT CLK100 as its clock source if sensed. Using the Clocks To use CLK100: Regardless of source, the clock bus output CLK100 can be accessed by AXIe instruments via the backplane or MultiFrame connection. 1 AXIe modules installed in a given chassis may access CLK100 via the backplane. 2 If the module is in a slave chassis in a MultiFrame, its clock source is MULTIFRAME INPUT CLK100 from the Master chassis. To use CLOCK OUT: You can extend the clock bus output to external instruments. These are instruments which cannot access CLK100 from that chassis, either via the backplane or MultiFrame connection. They may be external to the AXIe chassis or chassis system. Keysight M9502A/M9505A AXIe Chassis User Guide 77 Features and Functions Chassis Synchronization and Triggering The 10 MHz output is synchronous with the internal CLK100 signal. 1 Connect the external instrument’s clock input to the ESM’s front panel SMA CLOCK OUT connector. 2 Enable the external clock output by checking its Enable box on the Web Interface’s Chassis Health page. Triggering This section introduces the AXIe chassis’s trigger bus resources and some of the many ways you may use them. Any AXIe instrument can be triggered: - internally, based on its own automation or signals from DUT connected directly to it - through an externally applied trigger. - through the chassis backplane, The AXIe chassis allows you to trigger instruments—singly, in groups, or all instruments in the chassis—from different signal sources. The diagram below shows how the triggering resources are derived.

It allows any trigger input to be connected to any trigger output. Trigger Inputs There are many inputs to the Crosspoint Switch. Any input can be connected to one or more trigger outputs. The inputs include: - An external trigger (TRIGGER IN) applied at the ESM’s front panel SMA connector - Any of the 12 TRIG signals. As these lines are bidirectional, any AXIe module can source a trigger via the backplane using them. E-keying is used to manage traffic on the parallel trigger bus. - Any of the (two to five) STRIG signals. As these lines are bidirectional, any AXIe module can source a trigger via the backplane using them. - Any of the four event Flag signals (MULTIFRAME INPUT Flags 1 through 4) from the lower chassis connector - A MultiFrame SYNC signal (MULTIFRAME INPUT SYNC) from the lower chassis connector - A MultiFrame RUN Signal from the lower or upper chassis connector Trigger Outputs trigger signal: From the diagram, note that the ESM can output six types of - From the chassis backplane – TRIG – STRIG – SYNC - From the ESM front panel – TRIGGER OUT (SMA connector to any instrument) – MultiFrame Out Flags 1 through 4 (MultiFrame to upper chassis) – MultiFrame Out SYNC (MultiFrame connector to upper chassis) Each type of trigger output signal is explored in detail, after a closer look at the Crosspoint Switch. Keysight M9502A/M9505A AXIe Chassis User Guide 79 Features and Functions Chassis Synchronization and Triggering Crosspoint Switch The Crosspoint Switch provides the flexibility of routing many signal events from the backplane, flags or external trigger to different destinations. You can choose to enable and assign the input source for any or all of 19 signal destinations (trigger/timing resources to be output from the ESM). You can also source a logical 0 or 1 to force any destination low or high for test purposes.

Multiple outputs may be driven from the same input, but each output may have only one input assigned. The default input for all outputs is “Static 0”. If you don’t specify the input signal for a specific output signal, the input signal will be logic 0 by default for that output signal.

Clearing the check box writes a “0” to the register which disables that p particular buffer. Chassis Synchronization and Triggering Features and Functions 81 TR RIG10 TTRIG11 Features and Functions Chassis Synchronization and Triggering TRIG The TRIG bus (TRIG[0,11]) is a set of 12 Multipoint Low Voltage Differential Signaling (MLVDS) signal pairs with the following characteristics representative for each pair: - Multi-point and bidirectional to all slots plus the ESM - Backplane terminated with 80W at each end - Requires the instrument module to provide MLVDS buffers (blue lines) - TRIG bus resources are allocated through E-Keying) TRIG Bus (one of 12 pairs) ESM MLVDS Buffer Slot 1 MLVDS Buffer Slot n MLVDS Buffer 80W 80W Chassis Backplane Each TRIG line (signal pair) is a parallel bus, with connections to all logical slots (ESM slot plus the instrument slots). Any instrument in the chassis can send or receive a trigger signal using any of these lines. Use When: The TRIG bus’s multipoint topology makes it fast and direct for module-to-module triggering. To use a TRIG line as a trigger output: 1 Using the chassis Web Interface, on the Trigger Routing page, check the Output Enable box to enable the TRIG line as an output signal. 2 From the Input Signal drop down list, select an input signal for the output-enabled TRIG output. 82 Keysight M9502A/M9505A AXIe Chassis User Guide Chassis Synchronization and Triggering Features and Functions In the above example, TRIG 0 is enabled as an output, and will trigger when slot 1 sends a STRIG signal. TRIG 2 is also enabled, and will trigger when an external SMA trigger is applied. STRIG The STRIG signal is a Bidirectional Low Voltage Differential Signaling (BLVDS) star trigger with the following characteristics: – Point-to-point and bidirectional between the ESM (logical slot 1) and instrument slots (physical slots 1 through n) – Slot terminated with 100W differential and 50W series (optional) – All STRIG lines are trace length matched to 0.025") Slot 1 STRIG Bus Slot 2 Slot n BLVDS Buffer BLVDS Buffer BLVDS Buffer 50 100W50 50 100W50 50 100W50 ESM BLVDS Buffers 50 100W 50 50 100W 50 50 100W 50 Chassis Backplane Use When: The STRIG bus’s trace matched lines ensure the lowest skew when synchronously triggering multiple modules. Keysight M9502A/M9505A AXIe Chassis User Guide 83 Features and Functions Chassis Synchronization and Triggering To use a STRIG line as an output: 1 Using the chassis Web Interface, on the Trigger Routing page, check an Output Enable box to enable any individual slot AXIe Star Trigger line as an output signal. 2 From the Input Signal drop down list, select an input signal for each output-enabled AXIe Star Trigger output(s). In the example shown above, STRIG output is enabled for slots 1 through 3, and will simultaneously trigger these three STRIG lines when an input signal is received from any instrument on the TRIG 0 bus. SYNC The SYNC and CLK100 signals are a Low Voltage Differential Signaling (LVDS) star trigger and a star clock. SYNC provides an LVDS trigger signal, output at the next rising edge of CLK100 after the source trigger is received. The SYNC and CLK100 lines use identical fan out buffers and are trace length matched to 0.25” to operate as a pair, with the following characteristics: – Point-to-point between the ESM (logical slot 1) and instrument slots (physical slots 1 through n) – Slot terminated with 100W differential 84 Keysight M9502A/M9505A AXIe Chassis User Guide Chassis Synchronization and Triggering Features and Functions SYNC Bus (also typical of CLK100 signal) Slot 1 LVDS Buffer Slot 2 LVDS Buffer Slot n LVDS Buffer ESM LVDS 100W 100W 100W Buffers Chassis Backplane Use When: For truly synchronous applications, SYNC allows you to trigger multiple instruments both simultaneously and in sync with the reference clock. It can also be used as a general asynchronous star trigger output line. To use SYNC as a trigger output: 1 Using the chassis Web Interface, on the Trigger Routing page, note that SYNC is always output-enabled, as it is not bidirectional. 2 From the Input Signal drop down list, select an input signal for the SYNC output. In the above example, SYNC will be driven high synchronously on the next rising edge of CLK100 after an external SMA trigger input signal is received. To drive the line asynchronously, uncheck the Sync routed through crosspoint box; the external trigger will drive SYNC directly. Keysight M9502A/M9505A AXIe Chassis User Guide 85 Features and Functions Chassis Synchronization and Triggering TRIGGER OUT The TRIGGER OUT signal (also known as SMA TRIGGER OUT) is available on the ESM front panel TRIGGER OUT SMA connector with the following characteristics: – 3.3V CMOS drive, 100 mV minimum swing – 50W output termination Use When: TRIGGER OUT allows you to extend the trigger bus to instruments outside the chassis system or which require an external input. To use SMA TRIGGER OUT as an Output Signal: 1 Connect a cable from the chassis SMA TRIGGER OUT connector to the instrument you wish to trigger. 2 Using the chassis Web Interface, on the Trigger Routing page, check the Output Enable box to enable the SMA TRIGGER OUT signal as an output signal. 3 From the Input Signal drop down list, select an input signal to connect to the output-enabled SMA TRIGGER OUT output signal. 4 Under Conditions, you can select whether or not an 80-160 ns pulse is generated (always on the rising edge of the signal) and whether the signal is inverted just prior to the SMA TRIGGER OUT connector. The default is no pulse (“None”) and Passthrough (no inversion). In the above example, the SMA TRIGGER OUT output signal is enabled and it will output an inverted signal when a STRIG signal is received from slot 1. MultiFrame Flags Four BLVDS flags are provided on the MultiFrame cables. These flags can be distributed among any applications in a MultiFrame chassis that use asynchronous flagging. A flag is an asynchronous pulse, which any instrument in any chassis can generate in response to a signal transition or program command. 86 Keysight M9502A/M9505A AXIe Chassis User Guide Chassis Synchronization and Triggering Features and Functions Asynchronous flagging is accomplished by sending a flag and having the rest of the system act in a pre-configured way when it receives the flag. Any flag can be set or cleared (by assigning a static 1 or 0) or sourced, using the Web Interface. The Flag lines are bidirectional. Any chassis can enable any of the four Flag lines as a trigger bus destination or specify a Flag as a trigger bus source; the MultiFrame logic will only allow one source per Flag in the MultiFrame. Use When: The MultiFrame Flags provide for module to module signaling between modules in different chassis. To use a MultiFrame Flag as an output signal: 1 As you can see below, there are no Output Enable check boxes; the MultiFrame output signals are always enabled. 2 From the Input Signal drop down list, select the input signal for each MultiFrame Flag output signal. In the above example, Flag 1 will output a trigger when an input signal is received from an instrument on the TRIG 0 bus. Flag 2 will output a trigger when an input signal is received from an instrument on the TRIG 1 bus. Separately, you will need to program other chassis how to respond to a received MultiFrame flag. MultiFrame SYNC A SYNC line is provided on the MultiFrame cables. This can be used to synchronously trigger any AXIe instruments in the MultiFrame. To use MultiFrame SYNC as a Trigger Output A SYNC signal output from the master chassis in the MultiFrame will be passed to the other chassis over the MultiFrame cable, as MultiFrame Sync. To Output MultiFrame SYNC Keysight M9502A/M9505A AXIe Chassis User Guide 87 Features and Functions Chassis Synchronization and Triggering Using the chassis Web Interface, on the Trigger Routing page, from the Input Signal drop down list, select the input signal for SYNC. The master chassis will output the SYNC signal over the MultiFrame cable. Only one chassis in the MultiFrame may be set to output on the shared SYNC line. 88 Keysight M9502A/M9505A AXIe Chassis User Guide MultiFrame Operation Features and Functions MultiFrame Operation MultiFrame is a Keysight feature by which multiple measurement instruments in two or more chassis can be interconnected to appear as one integral instrument to the user. It includes hardware, software, and cabling specifications. In practice, the potential combinations of instruments which can share synchronization and triggering are numerous, and there is no practical limit on the number of chassis which you may interconnect. This section introduces basic MultiFrame connection and features, based on a simple MultiFrame of three M9505A chassis. MultiFrame operation is a Keysight feature, not an AXIe specification. Cables may be hot plugged. MultiFrame operation is different from multiple chassis operation; see “How does a multiple chassis system differ from a MultiFrame system?” on page 42 for more information. Use When: Use MultiFrame to increase the number of measurement modules which utilize a common time base or cross triggering to achieve correlation. The MultiFrame cables extend trigger and timing features to instruments not connected to the master chassis’s backplane. Shared Features All chassis (therefore all installed instruments) in the MultiFrame can share: Clock Source A common 100 MHz clock is sourced from the master chassis. The time offset for clock signals to traverse the cable and signal path between each pair of chassis is about 35 ns. The MultiFrame design calibrates this out, within about 600 ps of error. Cross Synchronization A common SYNC signal is sourced from the master chassis. The time offset for SYNC to traverse the cable and signal path between each pair of chassis is about 35 ns. The MultiFrame design calibrates this out, within about 600 ps of error. Cross Triggering Any instrument in the MultiFrame can source or receive a trigger, using any of the four Flag signals carried between chassis using the MultiFrame cables. MultiFrame cables (such as the Y1223A and 1224A) can be hot plugged; that is, you do not need to cycle chassis power when connecting multiple chassis. The slave chassis detects the presence of the MultiFrame cable and automatically switches its clock source to the master chassis’ clock output from the MultiFrame cable. Keysight M9502A/M9505A AXIe Chassis User Guide 89 Features and Functions MultiFrame Operation Interconnection You will need to interconnect the chassis using MultiFrame cables, then make LAN and PCIe connections between the chassis and host PC.

Keysight M9502A/M9505A AXIe Chassis User Guide 91 Features and Functions LVDS Local Bus LVDS Local Bus The M9502A and M9505A chassis backplane provides a local bus with 62 differential signaling pairs between each pair of adjacent instrument physical slots. This bus is the Low Voltage Differential Signaling or LVDS bus. Availability of these signal lines to any module will depend on vendor implementation of the Zone 2 connectors and related commands to manage signaling on the local bus. See “Interconnection” on page 90 for a look at these connectors. The chassis provides these local bus pairs on Zone 2 backplane connectors P20-P24. Most instrument modules will load connector P20 to access the trigger and timing bus, and will load connector J23 in order to utilize the AXIe base and data fabrics. Connector J23 provides the first 22 local bus pairs from backplane to module. Modules designed to take maximum advantage of the AXIe local bus will load additional connectors (P24, P21) and expand the local bus up to 42 or 62 signals to each adjacent module slot. If P24 (or P24 and P21) are loaded on your module, likely the vendor is utilizing the local bus. Check with the module vendor for any instrument in your AXIe chassis to determine if it utilizes the AXIe local bus and what functionality that feature provides you. Electronic Keying (E-Keying) Electronic keying is one of several capabilities AXIe inherits from the AdvancedTCA architecture. Like ATCA, AXIe promotes a fabric independent (also known as fabric-agnostic) backplane with respect to local bus connectivity. Each module plugged into a chassis may provide various communication protocols and hardware signaling that connect to pins on the backplane that link adjacent modules together. In general, the backplane itself does not provide internal buffering, so a link connection between two adjacent modules is simply a wired connection, either configured point to point or tied together on a common bus. This allows different modules in the system to establish their own link protocols provided a connection path exists. This flexibility frees the chassis configuration from dictating signal levels and protocols involved with any particular link. However, this flexibility presents a challenge: how to know whether the endpoints of a link are compatible or not. If you have modules in your system that are E-Keying compatible, refer to the documentation provided with your modules for detailed installation information. 92 Keysight M9502A/M9505A AXIe Chassis User Guide LVDS Local Bus Features and Functions E-Keying is a process in which compatible matches over links between different modules are identified and enabled to be used. The E-Keying process is handled by the chassis shelf manager. Each module in the chassis runs a Intelligent Platform Manager Controller (IPMC). These IPMCs interface with the shelf manager and each other using the Intelligent Platform Management Bus (IPMB). IPMB is basically a side channel protocol built on top of I2C that connects all modules in a chassis together. See the figure below. The shelf manager has two primary roles: - Manage the inventory and infrastructure of a chassis by communicating with IPMCs in the chassis: – Power requirements of the modules and managing the power module – Chassis cooling control of the fan module. – Individual Field Replaceable Unit (FRU)* inventory located in non-volatile memory that tracks ATCA and AXIe attributes from each module – E-Keying interconnection resources among modules: – Point-to-point (P2P) connections for base, fabric, and update channel interfaces. P2P connections are predominately what AXIe is concerned with. – Bussed resources for clock and metallic test bus (in ATCA). - External connectivity to a system manager, using an IPMI connection over Ethernet using a RMCP protocol. * A field replaceable unit is a part that may be removed from a system and exchanged with another part or returned to a factory for service Examples of FRUs may be a module card in a chassis slot, a fan tray, a power supply, and the chassis frame. Keysight M9502A/M9505A AXIe Chassis User Guide 93 Features and Functions LVDS Local Bus E-Keying Process When the chassis powers on, the first step the shelf manager does in point-to-point (P2P) E-Keying is read the backplane P2P connectivity records from the chassis modules. These connectivity records specify the P2P interconnections the backplane routes between specific slots and specific channels on each slot. Next, for each board loaded in the chassis, the shelf manager reads each board's Field Replaceable Unit (FRU) table for the P2P connections that board makes to the backplane. The shelf manager builds up a connection inventory of all the potential links a particular board can implement. This list is later used to examine the potential logical links each board has to other boards. Each potential link end has a link descriptor that identifies the following information: - P2P interface on the backplane and a channel number within that interface - The ports on a given channel that are involved with this link. This may include sets of differential signal pairs. - Finally, the link type which identifies the specification entity, such as PICMG 3.x, AXIe 1.0, or other specification that fully describes the link classification. The link type may also be an OEM-defined value using a 128-bit Globally Universal Identifier (GUID); each card may support up to 15 different GUIDs. The shelf manager goes through the backplane connection possibilities, identifying each end of a P2P connection and searches for a compatible link descriptors. If a pair of ends match, such as both ends are PCIe Express x4, then the shelf manager issues a “Set Port State (enable)” command to each board for that link. For the matches that are not found, the shelf manager issues a “Set Port State (disable)” command to ensure that incompatible link connections are kept off. As a final note, the shelf manager is truly agnostic about specific details of a link protocol. This permits new protocols to be added without modification to the chassis. For additional information on E-Keying, refer to the AdvancedTCA specification (http://www.picmg.org) and the AXIe specification (http://www.axiestandard.org). 94 Keysight M9502A/M9505A AXIe Chassis User Guide M9502A/M9505A AXIe Chassis User Guide 6 For Module Developers This chapter provides a detailed look at the AXIe chassis backplane and connectors, provided as a quick reference for AXIe module developers.

Whether you can develop individual instrument modules or modular instrumentation sets, communication between modules may travel across the backplane. Depending on your application, you have the flexibility create a variety of module types. - Instrument Module: An instrument module can go in any slot and will typically use the AXIe trigger bus resources. It will not typically use the local bus unless it is part of an instrumentation set. - Instrumentation Sets: AXIe provides the opportunity for you to create scalable, modular measurement and test systems which can occupy two or more chassis slots. – If you create a two-module instrumentation set intended to occupy adjacent slots, you can utilize up to 62 LVDS backplane local bus lines. This set would function in both the 2-slot and 5-slot chassis, and could be designed to function in any two adjacent slots of the M9505A. Refer to “LVDS Local Bus” on page 92 and “Electronic Keying (E-Keying)” on page 92. – You can also create instrumentation sets with up to five AXIe modules, and may implement backplane features and specify module placement as required. – Your multiple module instrumentation set can include an instrument hub module installed in slot 1. That hub may use AXIe trigger bus features, communicate between adjacent modules using the local bus, and provide the hub for a secondary x4 backplane data fabric to slots 2 through 5. 96 Keysight M9502A/M9505A AXIe Chassis User Guide ATCA and AXIe Requirements For Module Developers ATCA and AXIe Requirements Overview The Keysight AXIe (ATCA eXtensions for Instrumentation) chassis backplanes used in the M9502A and M9505A comply with the AXIe 1.0 Base Architecture Specification. AXIe 1.0 is based on AdvancedTCA® (ATCA) architecture, expanded with several eXtensions, all of which will remain electrically compatible with standard ATCA blades. These modifications provide timing, triggering, local bus signaling and data transport features. Keysight provides this chapter as a quick backplane reference for developers of AXIe instrument and instrument hub modules. It gives a brief explanation of how the M9502A and M9505A chassis implement AXIe features, and provides signal connection pin assignments for module backplane connectors. This summary of AXIe requirements is not intended to replace the applicable module design standards, which specify mechanical, electrical, and logical interfaces between module and chassis. AXIe modules must comply with: - AXIe 1.0 Base Architecture Specification, available at http://www.axiestandard.org - AdvancedTCA® PICMG 3.0® Specification, available at http://www.picmg.org Most ATCA modules should be able to work in an AXIe environment. Conversely, developers should design AXIe modules to be compatible in an ATCA environment. ATCA Requirements and Exceptions for AXIe 1.0 Mechanical modules. AXIe modules must meet all ATCA mechanical requirements for Exception: AXIe 1.0 chassis do not accommodate rear transition modules (RTM). Hard ware Platform (shelf) Management AXIe modules must incorporate the ATCA hardware platform management features. Exceptions: – AXIe uses an intelligent platform bus (IPMB) for platform management communication between the intelligent FRUs (for example: shelf manager, module IPMC) in a chassis. This IPMB conforms to the ATCA requirements for IPMB-0, but with no IPMB redundancy. – AXIe modules are not required to support the complete hot swap capabilities of ATCA. However, the module’s FRUs are required to support all of the operational states required for ATCA front boards. Keysight M9502A/M9505A AXIe Chassis User Guide 97 For Module Developers ATCA and AXIe Requirements – AXIe modules are not required to have the handle switches that sense the module’s insertion and impending removal from the chassis nor the blue hot-swap LEDs. – AXIe modules do not implement ATCA electronic keying, metallic test bus, and ringing bus. Power Distribution Dual power supplies are provided to each slot. AXIe Modules may use either or both supply feeds, and must be able to operate over a range from –53VDC to –45VDC. Data Transport AXIe modules must comply with all ATCA requirements for Zone 2 base and fabric interfaces. Exceptions: – AXIe modules only implement a single base interface channel (LAN channel 1). – AXIe modules may connect to data fabric channel 1 or channel 2, or both. – Data fabric channel 1, if used by the AXIe module, must implement a PCIe connection, operated from the supplied 100MHz reference clock (FCLK). – Data fabric channel 2, if used by the AXIe module, may implement proprietary protocols. – AXIe modules may connect to any of the CLK100, SYNC or STRIG signal pairs, any of the 12 AXIe TRIG pairs, and any number of available pairs on either or both local bus ports. Synchronization Clock AXIe backplanes maintain the bused topology of most Synchronization Clock signals, and devices implement the same MLVDS signaling levels as ATCA. Exceptions: – AXIe architecture expands the use of the ATCA Synchronization Clock Interface. The signals and connector pin assignments for AXIe modules differ from ATCA. No Update Channel Interface Exception: – The AXIe architecture does not implement the ATCA Update Channel Interface. AXIe backplanes implement a single bused MLVDS topology for the signals connecting to those Zone 2 connector contacts, and devices implement different signaling schemes as defined in the AXIe specification. AXIe modules must implement electronic keying appropriate to prevent incompatible connections between AXIe and ATCA devices installed in either system environment. 98 Keysight M9502A/M9505A AXIe Chassis User Guide ATCA and AXIe Requirements For Module Developers AXIe Extensions to AdvancedTCA® AXIe expands the ATCA specification with several eXtensions, Zone 2 customizations which include: - The AXIe timing interface, providing for specific clock distribution and signaling between the ESM and instrument slots 1 through 5. This interface includes timing resources SYNC, CLK100, and STRIG. See “Chassis Synchronization and Triggering” on page 75 for a complete functional description of these timing resources. - A 12 pair MLVDS trigger bus, TRIG[0,11], bused across all slots (the ESM slot and instrument slots 1 through 5). See “Triggering” on page 78. - A 62 pair local bus for signaling between adjacent instrument slots. See “LVDS Local Bus” on page 92. - The data transport fabric, a dual star x4 PCIe gen2 interface: – Channel 1 connects the ESM slot in a star configuration to provide an x4 link to each instrument slot – Channel 2 star connects slot 1—the instrument hub slot—in a star configuration to provide an x4 link to instrument slots 2 through 5 – Uses a distributed PCIe fabric reference clock (FCLK) driven from the ESM See “LVDS Local Bus” on page 92. - AXIe chassis implement an extended set of electronic keying records to assure consistent use of AXIe-defined backplane fabrics and resources. In the AXIe chassis, the ESM acts as logical slot 1 for base fabric signaling (LAN) and channel 1 data fabric signaling (PCIe) signaling in addition to shelf management. An AXIe instrument hub module is an instrument module that may optionally serve as a hub for vendor-defined protocols using the data fabric channel 2 star. An instrument hub module must be installed in slot 1 (logical slot 2), while other AXIe modules can be installed in any slot.

The backplane revision may be different between a 2 slot and 5 slot chassis. While it is possible to move an ESM from one chassis to another, the revision of the target chassis may not reside at the same revision level installed on the ESM (and its previous chassis). It is important to review the revision string after relocation to verify that the complete revision string is current. If not up-to-date, run through the firmware update process. <Axxxx>; <Bxxxx>... <xxxx> is a hexadecimal value for the firmware component. The actual content of these components is for Keysight internal use only. A firmware revision example: F2AX-1.3.37-0103-A002e-CA1.0-DA1.0-E1.3 This example shows an M9502A chassis with firmware revision 1.3.37. The backplane revision is 0103 and component A is at revision 002e, component CA is at revision 1.0, component DA is at 1.0, and component E is at 1.3. Refer to the M9502A/M9505A AXIe Chassis Firmware Update Guide for specific details regarding updating the chassis firmware. 110 Keysight M9502A/M9505A AXIe Chassis User Guide Troubleshooting Troubleshooting and Service Troubleshooting Overview The Keysight AXIe chassis is typically used as part of a complex test system, where system refers to the complete hardware/software system including: - One or more AXIe chassis with installed application modules - Connections from modules to devices under test (DUT) - A host PC running Keysight Connection Expert software, chassis and module device drivers, and programming environment software - LAN connection from the Host PC to Chassis Web Interface software - A compatible PCIe host cable adapter installed and configured in the PC - Compatible PCIe and LAN interface cables Troubleshooting that complete test system is beyond the scope of this chapter. Keysight recommends that to properly isolate complex operational problems, you take all routine steps to rule out a host software or connectivity issue. You may also wish to physically isolate the chassis from your DUT or installed modules, to distinguish a module hardware issue from a chassis hardware issue. As a temporary measure, you may (with the chassis powered down) partially remove a module without disturbing DUT connections, by removing it far enough to disengage it from the chassis backplane. Keysight recommends returning a failing chassis to Keysight Service. They will inspect, test and replace failed components, then retest the chassis. In general, an AXIe chassis has three major subsystems that can be replaced to service a failing chassis: - Fan Tray - Power Supply Unit (PSU) - Embedded System Module (ESM) This chapter assumes you can identify a suspected faulty subsystem, or have access to known good replacement subsystems you can swap to help isolate a hardware problem. Detailed step-by-step instructions are provided for fan tray, PSU, and ESM replacement. Normal Chassis Operating Behavior When the chassis is new and operating properly, familiarize yourself with its expected normal power-up and power-down behavior. This behavior involves these observable components: - Front panel power switch (mechanical feel and indicator light) - Rear panel circuit breaker (mechanical feel and resulting relay activation) Keysight M9502A/M9505A AXIe Chassis User Guide 111 Troubleshooting and Service Troubleshooting - ESM front panel STATUS light - PSU fan operation - Chassis fan operation - Web Interface Chassis Health page (fan speeds, fan settings, fan/cooling system status, backplane and slot temperatures) 1 OFF: With the chassis plugged into a correct power main, the rear panel circuit breaker open (OFF) and the front panel switch off (flush with chassis), all chassis lights should be extinguished. 2 BREAKER CLOSED: Close the circuit breaker (ON). You should observe: – The breaker handle engages with a solid click, overcoming slight spring pressure. – After a slight delay, you may hear a softer click; this is a relay closing in the PSU. You may not hear this relay close, due to PSU fan noise. – The front panel power switch may light briefly, then extinguish. – The two PSU fans will initially spin up to maximum speed, then gradually step down in speed (4-5 distinct steps) to idle over two seconds. These fans should remain on at idle with the breaker closed. 3 ON: Press the ON/STANDBY switch (turn the chassis ON). You should observe: – The switch will depress (ON) and will light. – The chassis fans will briefly turn on at high speed, then drop to and remain at low speed, until chassis load dictates otherwise. – The PSU fans will increase to and remain at high speed. – The ESM front panel STATUS light will cycle as follows: – Amber - ESM is booting; for about 20 seconds – Flashing green - briefly – Steady green - booted – Steady red - the ESM has detected failure and requires service. 4 WHILE ON: With the chassis ON, you can monitor real-time shelf management functions using the chassis’s Web Interface. 5 STANDBY: Press the ON/STANDBY switch again. You should observe: – The switch should return to the flush position (OFF) and its light will extinguish. – The ESM front panel STATUS light will extinguish. – The chassis fans will turn off. – The PSU fans will slowly drop in speed, while continuing to cool the PSU from operating temperature to standby temperature. – Once the PSU cools down, the PSU fans will return to a steady idle speed. 6 OFF: Open the circuit breaker (OFF). You should observe: 112 Keysight M9502A/M9505A AXIe Chassis User Guide Troubleshooting Troubleshooting and Service – The breaker handle releases spring pressure. – After a slight delay, you should hear a soft click; this is a relay opening in the PSU. You may not hear this relay open, due to PSU fan noise. – The front panel power switch may light briefly, then extinguish. – The two PSU fans will turn off. Chassis Hardware Troubleshooting Chassis Fans If module loads are kept within the 200W per slot rating and adequate ventilation is provided around the chassis, the chassis fans are designed to automatically cool the chassis. If the chassis powers up properly, the fans should be turning at all times, with speed in proportional to thermal load. There are a few reasons you may suspect a fan tray failure: - One or more fans does not turn. - A fan makes excessive bearing noise. - You observe reduced speed for one or more fans relative to the others. - One or more fans do not behave as described in “Normal Chassis Operating Behavior” on page 111. - You experience an overheat condition, whether detected by the chassis Health Monitor, module monitoring software or other means. In the event you experience unacceptably high chassis or module operating temperatures or other indications of fan failure, follow the procedure below. To Check Chassis Fan Operation In the event you experience unacceptably high chassis or module operating temperatures, or other indications of fan failure, follow the procedure below. 1 Visually check that all three (M9502A) or six (M9505A) fans are turning. If any fans are not turning, check for and remove obstructions. If there is evidence of excessive buildup on the fan blades, remove the fan tray to clean and reinsert it (see page 124), and recheck. If any fans still do not turn, replace the fan tray. Else continue. 2 Using the Web Interface, access the Chassis Health page. In the Sensors section, each fan is listed individually, with real time speed in rpm. 3 The six speeds should be reasonably close. Identify any that turn more slowly than the group. Any large deviation may indicate reveal early signs of fan failure. 4 Below the fan speed readouts are your fan settings. You may set a higher fan speed to see if the fans are responsive. Keysight M9502A/M9505A AXIe Chassis User Guide 113 Troubleshooting and Service Troubleshooting 5 For fan noise problems, make sure which fans are noisy or not turning properly, by visually inspecting both the PSU and chassis fans through the side of the chassis. 6 For all routine chassis fan failures, replace the fan tray assembly (see “To Replace the Fan Tray” on page 124). For PSU fan failures, replace the PSU (see “To Replace the Power Supply Unit” on page 118). If the fans are operating correctly and you still have high temperatures, reduce your chassis load or troubleshoot installed modules. Power Supply Unit (PSU) The PSUs are self regulating, constant voltage supplies that will shut themselves down (or not power up at all) if they are out of spec. These are standard ATCA supplies. The PSU operation is binary. If the supply is delivering voltage within a very wide range, it will turn on its output and power up the chassis. You can then view PSU voltages using the Web Interface. If the system does not power up, it likely has failed and should be replaced (see “To Replace the Power Supply Unit” on page 118). Embedded System Module (ESM) If, upon power up, the ESM does not boot to a steady green STATUS light, replace the ESM (see “To Replace the Embedded System Module” on page 124). If replacing the PSU or ESM does not correct an operating problem, and the ESM still fails to boot to a steady green STATUS light, the problem is in the remainder of the chassis; replace it. To Reset ESM DIP Switches The ESM has several sets of dual in-line package (dip) switches. Should you believe any of these may have been changed, you may verify and reset them to their correct positions; see photo and table below. Most of these switches are reserved for factory testing purposes or reserved for future use and should not be changed. 114 Keysight M9502A/M9505A AXIe Chassis User Guide Troubleshooting Troubleshooting and Service SWC1 SWC2 SW1 SW2 SW3 SW5 SW4 Switch Number on ESM SW1 SW2 SW3 SW4 SW5 SW6 SWC1 SWC2 Factory Switch Setting 0011 0111 1111 N/A N/A 2 - left (see below) 1- left (see below) 0010 Left SW6 What it Does JTAG Testing (see silk-screen) JTAG Testing (see silk-screen) JTAG Testing (see silk-screen) Reserved (momentary contact) Reserved (momentary contact) Set PCIe Gen 2 (default) speed or Gen 1 speed Reserved Upstream Port Internal/External PCIe setting (see silk-screen) A DIP switch (SW6) on the ESM configures the PCIe operational mode setting.

Turn chassis power off before setting this switch. After setting the switch to either position, the host PC must have power cycled to re-enumerate the chassis. 116 Keysight M9502A/M9505A AXIe Chassis User Guide User-Replaceable Parts Troubleshooting and Service User-Replaceable Parts The following user-replaceable assemblies and accessories are available from Keysight: AXIe Mainframe Description of Parts Kit or Subassembly Keysight Part Number M9502A 2-Slot Chassis Fan Tray M9502-00017 2-Slot Chassis Power Supply Unit M9502-64800 AXIe Embedded System Module (ESM) M9505-00130 2-Slot Chassis Bumper Kit (includes one handle) N5650-00018 2-Slot Chassis Rackmount Kit N5650-00020 AXIe Filler Panel Module N5650-00080 5-Slot Chassis Fan Tray M9505-00017 5-Slot Chassis Power Supply Unit M9505-64800 AXIe Embedded System Module (ESM) M9505-00130 5-Slot Chassis Bumper Kit (includes two handles) M9505-47901 5-Slot Chassis Rackmount Kit M9505-00020 AXIe Filler Panel Module N5650-00080 M9505A Other parts originally supplied with the mainframe may be available from Keysight.

Frequently asked questions
The Keysight M9502A and M9505A AXIe chassis are modular instrument chassis that allow you to connect multiple instrument modules to a common chassis frame, power supply, cooling system, and data bus. They offer features such as a PCIe Gen 2 data bus, Gigabit LAN hub, local bus for module-to-module signaling, and host PC connectivity. The chassis also include an Embedded System Module (ESM) for managing chassis functions and monitoring module health. They support synchronization and triggering for coordinated operation of multiple modules.
You can install instrument modules into any available slot in the chassis. To install a module, you will need to align the module with the slot and slide it in until it clicks into place. Ensure that the module's retaining screws are tightened to secure the module to the chassis and make the ground connection.
The Keysight M9502A and M9505A AXIe chassis require a standard AC power supply. The specific voltage and current requirements are provided in the chassis's specifications. Ensure that the power supply is properly grounded to minimize shock hazards.
You can connect a host PC to the chassis using either the PCIe or LAN port on the ESM. The specific connection method depends on the type of host PC you are using and the software you are running. Refer to the AXIe Chassis Startup Guide for more detailed instructions.
