The Automated Test Blog

I just finished reading the book Bill and Dave: How Hewlett and Packard Built the World’s Greatest Company. Its a good read that focuses on the personal story of how two engineers built the most successful high technology company of their generation. Its also a good reminder of how much Hewlett and Packard laid the groundwork for the current generation of technology companies. Among other things, they pioneered “Flex-time”, the “Open Door” policy, “Management by Walking Around”, profit sharing, employee stock purchase plans, casual Fridays, “10% time” MBOs, company barbecues, and the cubicle (but don’t hold that last one against them!). All of us in the technology field owe a lot to those two pioneers.

One the biggest signs of success factors of PXI has been the increased adoption by major test and measurement vendors. Even though at times they have been hesitant to wholeheartedly support the PXI standard, Agilent, has several product lines in PXI:

•  A line of PXI-based high performance signal generators (N6030A)
• PXI digitizer modules, from their acquisition of Acqiris
• PXI Optical test instruments, form their acquisition of PXIT

Last week, Agilent released new PXI modules in their optical test product line. Their press release notes that the modules offer their customers “a smaller, faster, more cost-effective solution” - precisely the primary benefits of the PXI platform.

PXI is celebrating its 10 year anniversary in 2007. Richard Quinnell at Test and Measurement World recently wrote about PXI’s anniversary, highlighting the compatibility it has achieved during this time. For me, its been remarkable to see the growth and changes in this marketplace over the past 10 years, especially all the times that PXI vendors achieved “the impossible”. Here are a few of my favorites:

• 1999 - 50 members and over 200 products. The first few years of the standard saw a rapid adoption by vendors and the release of a lot of products. Grow exceeded expectations in every dimension.
• 2002-PXI’s entry ito RF. Prior to the release of products by National Instruments and Aeroflex, certain vendors had been outspoken that “you could never do RF in PXI”. Last year, Phase Matrix announced that they are taking PXI all the way up to 26.5 GHz!
• 2003 - PXI systems shipments exceed VXI. By 2006, PXI vendors shipped over 10,000 systems per year - 3 times larger than VXI at its peak. Naysayers claimed modular systems would never be mainstream.
• 2004- A 512 Cross-Point Switch. With the release of the PXI-2532, National Instuments put to rest those that claimed the Achilles heal of PXI was switch density.
• 2005-PXI Express. The PXI Systems Alliance did a remarkable job incorporating new technology to achieve a 45-fold increase in bandwidth while preserving backward compatibility. Those that claimed PCI Express would break compatibility become suddenly quiet.
• 2007 - Agilent joins the PXISA. Agilent Technolgies joined other big name vendors such as Advantest, Aeroflex, Keithley, National Instruments, Rohde & Schwarz, and Teradyne. So much for not having any big name companies in PXI!
