M9010A 10-slot PXIe Chassis

PCIe Gen 3, 3U, 24 GB/s 

Introduction

The Keysight Technologies, Inc. M9010A PXIe 10-slot Gen 3 chassis delivers flexibility, compatibility, and performance in a smaller form-factor ideal for bench-top applications. With 8 PXIe hybrid slots, it gives the system designer flexibility to mix and match the number and location of PXIe and hybrid-compatible modules. The ultra-high performance, PCIe® switch fabric can operate up to Gen 3 providing up to 24 GB/s of system data bandwidth. The new cooling design provides exceptional per-slot cooling while producing much less fan noise. It is also designed for easy maintenance and has features for combining multiple chassis together or integrating with other non-PXI instrumentation.

Key Features

• 8 PXIe hybrid slots, 1 PXIe timing slot, and 1 PXIe system slot

• Powerful cooling with low fan noise

• Ultra-high performance Gen 3 PCIe switching with a two-link (x8, x16) system slot and x8 links to the hybrid/timing slots

• High data bandwidth (maximum 24 GB/s system and 8 GB/s slot-to-slot)

• Multi-chassis power-sequencing and front panel external trigger inputs/outputs

• Specified up to 55 ºC and 10,000 ft operating conditions 

Hardware Overview

Backplane Configuration

The M9010A PXIe chassis provides 8 hybrid-compatible slots for flexibility and compatibility. It utilizes a single PCI segment with PCIe-to-PCI bridge (Figure 1) for the hybrid slots. The PXIe slots are also organized into two trigger bus segments with configurable interconnections between segments. Two front panel trigger ports (SMB) are connected to the PXI (0:7) trigger bus. This enables easy integration with non-PXI instruments.

Ultra-High Performance PCIe Fabric

The M9010A PXIe chassis is built around an ultra-high performance PCIe switch fabric that operates at up to Gen 3 speeds. All of the PXIe peripheral slots have a x8 PCIe link providing a maximum data bandwidth of 8 GB/s each. The two-link system slot has a maximum data bandwidth of 24 GB/s when all 24 PCIe lanes are utilized. When combined with the M9023A PXIe system module, M9049A PCIe adapter, and an external PC with a Gen 3 x16 PCIe slot, up to 16 GB/s of data bandwidth can be achieved between the PC and PXIe chassis.

The advanced switch fabric also allows for peer-to-peer communications. Any peripheral slot can communicate with any other peripheral slot without utilizing the system slot PCIe links. The PCIe switches have a large crossbar capacity, allowing flexible placement of peer-to-peer modules without impacting data bandwidth. 


Innovative Cooling

The M9010A has been optimized for both module cooling and acoustical fan noise resulting in a lower-level of fan noise when high-performance PXIe modules are used. It utilizes auto-speed fans and internal temperatures sensors to give the user complete control over module temperatures. Unlike many other PXIe chassis, the fan-speed is controlled using temperature sensors located on the top of the backplane, in the path of the module cooling air exhaust. This enables the M9010A fans to react to actual changes in module temperatures, instead of ambient air temperature readings. This results in lower module operating temperatures when the AUTO fan setting is used. When the HIGH fan setting is used, the acoustical emissions are much lower than the typical PXIe chassis. 

System Monitoring

The M9010A PXIe chassis has a complete set of system monitoring functions for power rail voltages, module exhaust temperatures, and fan speeds. For temperature measurements, the chassis utilizes 6 temperature sensors located on the top of the backplane, in the path of the module exhaust. Chassis operating conditions can be monitored via a software API or the soft front panel interface.

A DB-9 connector is also available at the rear of the chassis for remote inhibit and power rail monitoring. The chassis has configurable alarms that can be monitored via front panel LEDs, soft front panel interface, or software API.

Easy system expansion

When connecting multiple PXIe chassis together, the power- sequencing becomes very important especially when an embedded controller is used. The M9010A PXIe chassis has special features built-in to make this easy. Cat 5 cables with RJ-45 connectors are used to interconnect the chassis. In a multichassis configuration, a user can press a single chassis power button to enable all chassis in the system to power-up. If an embedded controller is being used, its chassis will automatically be powered up last. This provides a consistent, repeatable power-up sequence.

The M9010A also has two front panel trigger SMBs which can be used for input/output triggers. These trigger ports connect to the PXIe backplane making it easy to connect triggers between multiple chassis or non-PXIe instruments

Software Platform

Drivers and Trigger Manager

The M9010A PXIe chassis comes complete with IVI. NET, IVI-C, and LabVIEW drivers. Windows 7, 8.1, and 10 operating systems are supported, and applications can be created using a variety of software tools including LabVIEW, LabWindows/CVI, MATLAB, VEE, Visual Basic, VisualStudio.NET (C/C++, C#, VB.NET).

Soft Front Panel Interface and Trigger Manager

A soft front panel (SFP) interface (Figure 2) and PXIe-9 compliant trigger bus manager are provided with the M9010A chassis. The SFP can be used to monitor and control the PXIe chassis and has the following functions:

• Configure fan control front panel trigger ports

• Monitor chassis fan speed, chassis temperatures, rail voltages, and PCIe links

• Configure alarms for fan speed, temperature, rail voltage, reference clock

• Run chassis self-test and update chassis firmware

• Review chassis information
