Guest Column: Time Matters — How Power Meters Measure Fast Signals
9/8/2008
Modern wireless and cable transmission technologies, as well as radar systems, present demanding challenges for device and system developers. Manufacturers of test and measurement equipment are driven to offer products that fully support today’s needs, while anticipating the requirements of future technologies. Accuracy has always been a critical requirement in the test and measurement world, but modern technologies demand another must-have — highest data acquisition and processing speeds to allow accurate measurements of complex signal waveforms. This article describes the different techniques RF peak power meters employ to meet these challenges

Strategies For Signal Intelligence: From Antennas To Analysis
4/14/2008
By National Instruments
Signal intelligence describes a broad range of applications ranging from communications jamming, packet sniffing, and identification of interference or pirating signals. While this article will discuss many of the specific needs for each application, it will primarily focus on the techniques required to analyze intermittent or “bursty” RF signals... -
Connectivity Options For RF Switch Applications
3/13/2008
By National Instruments
When designing an RF switch system, it is easy to focus on the performance of the switch module while neglecting smaller system components such as cables and connectors. However, in order to obtain optimal system performance you must place as much attention on choosing the right cable and connectors for your system as you would on choosing the right switch module. To learn how to choose the right cables and connectors for your system, it is important to understand the advantages and disadvantages of the various options available... -

Highs And Lows Of Electronic Warfare
The next chapter of electronic warfare is all about precision and low visibility. Col. Mark Dotson said the Army’s new EW strategy is centered on, “using low power to affect the signal and to affect it in such a way that it may not even be detectable that you’re interfering with what they’re doing.”
