Eye on Standards

- June 28, 2012

In Eye on Standards, Ransom Stephens will be tracking the developments with current, evolving, new, and emerging technology standards and what they mean for you, the test engineer. From the IEEE to ANSI, IEC, and consortiums such as LXI, PXIe, USB, and others, Stephens will be there to help you close the ‘eye’ on your next test project.

Ransom Stephens is a technologist, science writer, novelist, and Raiders fan.
