Building LXI-Based Test Systems LAN eXtentions for Instrumentation Building LXI-Based Test Systems Welcome to this series of presentations on LXI. If you are new to LXI, you should watch Connecting with LXI first. It will cover some key aspects of any LXI Device. The focus of this presentation will be on connecting multiple LXI Devices together to build an LXI-based Test System. LXI Consortium Presentation May 14, 2017

Building LXI-Based Test Systems LAN eXtentions for Instrumentation Building LXI-Based Test Systems Key points of this presentation were taking from the LXI Consortium document Building LXI-Based Test Systems. That document can be found on the LXI Consortium web site and provides much more detailed information about recommended LAN configurations, communicating with LXI devices, security, and best practices. LXI Consortium Presentation May 14, 2017

LXI Products and Productivity Over 3600 Instruments are LXI Conformant All LXI Devices connect the same over LAN All LXI Devices have IVI Driver for quick programming Most LXI Devices have Web Monitoring/Control LXI boxes, LXI to PXI, and LXI to VXI choices Established in 2004…over 55 of the top T&M companies sponsored and developed this technology, and there are more than 3600 products in over 50 different product families. LXI (LAN eXtensions for Instrumentation) is the current and future standard for Test and Measurement Systems. Prior to this standard there were LAN-based instruments, but there were as many different ways of configuring these devices as there were products. With the LXI Standard, all devices behave the same when connecting to LAN, they all come with easy to use IVI Drivers, example programming, and most have added Web Pages for monitoring and controlling functionality. LAN Connectivity is common, fast, inexpensive, and reliable…all features you want in a test system. …building a Test System hardly gets better!

LXI expands Test System access You want to work here… 14000 km 60 meters For a test system engineer, it is usually inconvenient and uncomfortable to work next to the test system. You want the comfort of a quiet office environment to develop your test programs, and you may be supporting a test system not even in your facility. …but your Test Systems are way over there …and in a noisy environment.

Fast development/troubleshooting with LXI You can Remote Login to the Test System PC LXI Devices on test system share a private LAN with PC IVI Drivers provide quick access to LXI Device functionality You can monitor/debug your code via Web Pages Test Program Web Page Scope With a Test System full of various signal generation, measurement, and switching products, you need a way to see what is going on… It is a common solution to Remote Login to your test system…nothing special about that. But, with LXI Devices, that remote connection then provides Web Page access to the various measurement and control devices. For example, a test is failing, so you step through the test program looking at the result on the Scope Web page. Hmmm…not right…so, you check the switch path using the Switch Web Page. Ah…wrong combination of switches…problem solved! And, you did it from the comfort of your desk. Web Page Switching

A system consists of multiple LXI Devices… In the presentation Getting Started with LXI, you learned how to connect a single instrument to your LAN, discover it, and control it. Building an entire system requires additional considerations we will discuss in this presentation. Performance and Security are two very important topics in deploying your new test system. These are so important, we created two additional presentations just to cover those topics. For now, let’s keep our focus on assembling the hardware and software that connects everything together, allows programming, and gives you the luxury of monitoring your devices with the LXI Web Pages. …here is one possible configuration. Are there others?

Multiple configurations to choose B C D Here are four configurations discussed in the Building LXI-Based Test System document found on the LXI Consortium Web Site. That document discusses various criteria for choosing one configuration over another. Briefly: A – All of your test instruments and your test computer are on the same LAN as everyone else in your company. Great for sharing, but potential outside interference with tests is unavoidable B – Your test system computer is isolated from company LAN by a router. Avoids interference but becomes more difficult for others to log into the test computer D – Is essentially the same as B, except the router is also Wireless, so you can place one or more instruments in locations difficult to connect with LAN cables C – This is probably the most recommended configuration, since it offers easy access to the test computer, but the instruments are isolated from the company LAN This presentation will focus on C, and you will learn some of its key features and benefits. …we’ll pick C… a recommended configuration

Get Ready – What do you need? What you need Computer with two LAN Ports LAN Switch with 8-16 ports LAN cables Your LXI Devices VISA I/O Library LXI Discovery Tool For Configuration C, you need a computer with two LAN ports. One will connect to the company LAN, and the other creates a private subnet for all of the LXI Devices. A LAN switch provides the connection to each LXI Device, and the LAN cables can be neatly routed within your rack. Although you don’t need any special software to bring up the LXI Device’s Web Pages, you need the VISA IO Library IVI Drivers if you want to program the LXI Devices. Companies like National Instruments and Keysight provide comprehensive solutions for the VISA IO Library. Each LXI Device is required to provide an IVI Driver, which is obtained from the particular company website. The ivifoundation.org website provides a listing of all IVI Drivers with pointers to each company’s website for download.

This is simple… What happens? Computer and LXI Device ask DHCP Server for IP address That DHCP Server provides a wonderful connection experience This configuration was covered in the LXI Getting Started presentation. It is simple. You plug the device into the company’s LAN, and the DHCP server gives it an IP address. Unfortunately, that IP address could be anything. You can discover it with tools from the VISA IO Library or using the LXI Discovery Tool. However, when connected to the company’s LAN, those tools will also discover every other LXI Device. …but, there are challenges for a Test System

Configuration C is a bit harder… What happens? Computer NIC #1 gets its IP address from DHCP Instruments on NIC #2 fall into an Auto IP configuration 169.254.x.x Getting back to Configuration C, we have isolated the LXI Devices from the company LAN. We have also isolated ourselves from the DHCP Server…which automatically assigned IP addresses. However, the LXI specification requires that devices connected as seen above will drop into AutoIP when no DHCP Server is discovered. AutoIP also assigns somewhat arbitrary IP addresses in the 169.254.x.x range. For this configuration, most Test Engineers would want to assign fixed IP addresses to each LXI Device. How do we do that? …Auto IP takes longer and IP addresses are indeterminate …but this gets us almost to the configuration we want

First - Reconfigure NIC #2… The NIC #2 LAN interface likewise dropped into the AutoIP range of addresses. It too should be assigned a static IP address. TBD text when the image is captured. NIC #2

First - Reconfigure NIC #2… We want to assign a private subnet address range using a static IP on NIC #2. The range 10.x.x.x is commonly used for static IP.

LXI Discovery… www.lxistandard.org The LXI Discovery Tool can be used to only search for LXI Devices on the private subnet – NIC #2, using the Advanced Menu. Once all LXI Devices are found, you can bring up each LXI Device’s Welcome Page

Reconfigure LXI Device IP… LXI Welcome Page Monitor/Control LAN Configure If you have multiple LXI Devices that are all the same model number, you can press the ID button, and an indicator will flash on that device, either on the screen or a blinking LED. There will be some sort of indication, labeled or icon, that indication LAN Configuration. That is where we need to go to change the IP address. Identify VISA String

Reconfigure LXI Device IP… LXI LAN Configuration Page Device IP Static IP The LXI Device will be shipped configured for Automatic or DHCP. To make the device’s address static, you choose Manual. Note the gateway is NIC #2’s IP address. NIC #2 IP

LXI Discovery… You repeat the previous operation for each LXI Device, and the final result is all of the LXI Devices are on the same subnet as NIC #2.

VISA IO Library and IVI Drivers Install VISA IO Library Keysight Technologies : www.keysight.com National Instruments : www.ni.com Install IVI Drivers IVI Foundation has pointers to all conformant drivers: www.ivifoundation.org IVI Drivers come with Examples in multiple languages IVI-C, IVI-COM, and IVI.NET Now it’s time to install the really software – the means to which you can develop and control these instruments. Two of the top choices for the I/O Library called VISA are Keysight and National Instruments. Those companies also include discovery tools for discovering LAN, USB, and GPIB interfaces. Since every LXI Device is required to supply an IVI Driver, you have an easy means to programming your systems instruments quickly. IVI Drivers are all registered on the IVI Foundation website, so if you are putting together a system, you can find pointers to the driver software at the various vendors supplying your test equipment. The IVI Foundation maintains the standards for both VISA and IVI.
