Advanced Capabilities of PXI-Based Semiconductor Test Systems

The ongoing challenge for today’s semiconductor test engineers is to identify and create new test solutions that can offer significantly lower test costs as well as address the need for configurable, open-architecture, flexible test solutions that can provide comparable features to proprietary ATE platforms. In particular, for test requirements with low to moderate volumes — such as pilot production, verification, and focused production test applications — the need for flexible and cost-effective ATE solutions is particularly acute. For these applications, test engineers historically have relied upon legacy test systems that have a low acquisition cost, but high operating costs or in-house designed rack-and-stack solutions. However, semiconductor test system solutions based on the PXI platform have made significant advancements in functionality and performance over the past three or four years, offering test engineers a viable alternative for both current and future test needs.

Calibration Requirements for Testing Coupling-Decoupling Networks

Coupling-Decoupling Networks (CDNs) are the unglamorous workhorses that get “hitched up” to an impulse generator in order to perform impulse testing on powered equipment. As such, performance and calibration requirements for CDNs have not been specified to the same level of detail as the impulse generator. This is no longer the case with the Third Edition of IEC 61000-4-5, the international standard for surge immunity testing.

NASA Monitoring Technologies Shake Up Earthquake Prediction

The seconds to minutes of advance warning of an earthquake can allow people and systems to take actions to protect life and property from destructive shaking. Earthquake early warning systems use earthquake science and the technology of monitoring systems to alert devices and people when shaking waves generated by an earthquake are expected to arrive at their location. NASA has been one of the agencies at the forefront of earthquake early warning technology for many years, and new monitoring techniques developed by NASA are shaking up the way earthquakes are predicted.

Celebrate Pi Day with NASA Goddard and Discover Pi-Sat

The Innovative Technology Partnerships Office (ITPO) at NASA’s Goddard Space Flight Center (Goddard) in Greenbelt, MD, invites you to celebrate Pi Day on March 14 and discover Pi-Sat. Current technology trends indicate a shift in satellite architectures from large, single satellite missions, to small, distributed spacecraft missions. At the center of this shift is the smallSat/cubesat architecture.

NASA-Developed Platform Integrates Sensors with Smartphones

Carbon-nanotube-based gas detectors paved the way for interchangeable smartphone-savvy sensors. In 2007, when the Department of Homeland Security (DHS) issued a call for a sensor that could equip a smartphone with the ability to detect dangerous gases and chemicals, NASA Ames Research Center scientist Jing Li had a ready response. She had been developing the use of single-walled carbon nanotubes that respond to various gases and compounds for use in NASA applications such as evaluating planetary atmospheres, detecting chemicals around rocket launch pads, and monitoring the performance of life-support systems. Her proposal was awarded funding in 2008, but she needed a way for the device to “sniff” the air for samples, and a system that would allow it to interface with a smartphone.

Defining and Measuring “LOOSE TIGHT BUFFER” in Fiber Optic Cables

As the optical fiber and cable industry unfolded, several terms were coined to describe specific properties that were new and different from conventional wire processing. One of those that stayed around was the term “Loose Tight Buffer.”
