From Steve Schink,
Chairman of the Board, LXI Consortium


Welcome to the first issue of the LXI Newsletter in China!

Our intention is to share information with you on the LXI Standard and its many applications in the Test and Measurement marketplace. We also want to introduce you to the LXI Consortium, which has the mission of developing, maintaining and promoting the LXI Standard worldwide.

The LXI Consortium held its first meeting at the end of 2004 with a dozen T&M companies. It released Revision 1 of the LXI Specifications one year later and companies immediately started building LXI conformant instruments. LXI has become the fastest growing T&M standard since its inception, and we now have over 50 members worldwide. There are more than 2790 certified LXI products from 41 vendors in over 294 different product families.

LXI for Everyone

Peter Plazotta
Founder and Chief Engineer,

The LXI Consortium has been in existence for over 12 years, and we have had unprecedented Test and Measurement (T&M) industry success with the development and adoption of the LXI (LAN eXtensions for Instrumentation) Standard. 

Our vision for the future of the LXI Consortium is to maintain and expand the global adoption and utilization of the LXI standard by T&M instrument vendors and their customers. Global adoption and utilization of the LXI standard by instrument vendors will ensure a lower-cost, consistent, predictable and multi-vendor interoperable experience for our customers building network-based T&M test systems.

Recently, the LXI Consortium released the LXI Reference Design official 1.0 version for use by the LXI membership.  We are excited to be offering our current and future members what we believe is a T&M industry first, the source code and support for LXI Consortium members to implement the LXI Standard!

LXI is the LAN Standard for Test and Measurement

Every serious test interface makes bold claims about flexibility, scalability and performance—but only one extends the cost-effective power of LAN. LXI is the robust system backbone for today and tomorrow, and it lets you easily connect the system you need: big or small, local or remote. Thousands of instruments have passed LXI conformance testing, and every one of them lets you use the connection you already know. If you are designing new test systems or are upgrading an existing test system—consider LXI based instruments in your test plan.

Easily Connect the System You Need
LXI instruments use an intuitive Web interface making it fast and easy to connect and configure. You can simply open the instrument home page in any browser. The speed and simplicity of LXI works seamlessly in hybrid systems with test interfaces that include GPIB, VXI and PXI instruments. And, it’s easy to set up a simple local connection or use the corporate LAN with any type of Ethernet connection (100 Mb, 1Gb) and WLAN. You can go beyond the core standard with LXI Extended Functions on select instruments and achieve greater performance with hardware and LAN -based triggering and synchronization.


IVI Web Forum Question and Answer:
In general why IVI-C, IVI.COM or IVI.NET?

Answered by Kirk Fertitta, Pacific Mindworks
for the
IVI Web Forum

Note:  Offering an IVI driver is a requirement for all LXI-conformant instruments.  The IVI Web Forum is hosted by the IVI Foundation.  You can sign up at www.ivifoundation.org.

In general why IVI-C, IVI.COM or IVI.NET?

This is a pretty involved topic – and a contentious one, but I’ll share what I tell folks when building an IVI strategy. The most important factor is considering the development environment (ADE) that your customers primarily work in.

Few would argue that IVI.NET provides the best end-user experience for those working in a .NET environment, such as C# or VB.NET.However, IVI-COM drivers include .NET interop assemblies (i.e. .NET “wrappers”) that have provided a very good .NET end-user experience for many years.IVI-C drivers don’t fare as well in .NET, as they require the use of somewhat tedious attributes to call into the native C DLL.There are some vendor-specific wrapper generation tools for IVI-C in .NET, but there is no IVI standard mechanism for doing this and interchangeability across vendors isn’t really supported with IVI-C.


Thanks to all our readers.

R&S®RTO oscilloscopes combine excellent signal fidelity, up to 16 bit resolution and high acquisition rates with a compact device format in the 600 MHz to 4 GHz class.

Pacific Power Source AFX Series programmable AC, DC & AC+DC
AFX models are available in power levels ranging from 9kVA to 60kVA. All models are based on a proprietary, all-digital, power conversion technology platform that supports a set of formerly unavailable features and capabilities used in programmable power sources. 

Tektronix MDO4000C Mixed Domain Oscilloscope
6–in–1 Versatility PLUS High Performance in One Powerful Oscilloscope
The new MDO4000C includes up to six built-in instruments, each with exceptional performance to address tough challenges.

Keithley 2281S-20-6 Precision DC Supply and Battery Simulator, 20V, 6A
The Series 2281S Battery Simulator and Precision DC Power Supply innovatively integrates battery simulation with the functions of a high-precision power supply and battery testing.

Keysight N8937APV Photovoltaic Array Simulator, 1500 VDC, 208 VAC
The Keysight N8937APV Photovoltaic (PV) Array Simulator enables you to develop, verify and optimize the performance of your inverter maximum power point tracking algorithms.

Pickering Interfaces New High-Density Switching Matrix (model 60-553)
This new matrix is a 1024x4 dual bus 1-pole matrix in a compact 1U full rack width enclosure. The product has been designed specifically to support high relay closure counts to optimize its use with a digital multimeter (DMM) or source meter for checking for insulation problems between a single contact and all other contacts in the unit under test (UUT), requiring the closure of up to 1024 crosspoint relays.

VTI Instruments RX0124
The RX0124 is part of VTI's RX series family of rugged instruments with built in sensor signal conditioning. The RX0124 is designed to address all strain/bridge measurement requirements for use in a harsh test cell environment.
