Electronic warfare development targets fully adaptive threat response technology

August 19, 2013 8:17 am | News | Comments

When U.S pilots encounter enemy air defenses, onboard electronic warfare (EW) systems protect them by interfering with incoming radar signals: a technique known as electronic attack (EA) or jamming. Conversely, electronic protection technology prevents hostile forces from using EA methods to disable U.S. radar equipment assets. A research team is now developing a new generation of advanced radio frequency jammer technology.

Using Logic Analyzers to Reveal Digital System Problems

August 5, 2013 1:52 pm | by Brad Frieden, Product Planner, Agilent Technologies Inc., Santa Clara, Calif. | Agilent Technologies Inc. | Articles | Comments

Today’s digital designs are evolving in a variety of ways, prompting new approaches to design, simulation, measurement and debug. One change is the use of more serial buses. Another is the use of system-on-a-chip (SOC) integrated circuits or advanced field-programmable gate arrays with SOC capability. Despite this evolution, there's still a role for classic parallel buses in many designs and the need to measure those buses.
