As one of the most important instruments for electrical test in a lab or in the field, signal and spectrum analyzers serve multiple purposes across a range of applications, from communications, to ...

Like most modern radio communications devices, wireless local-area networks (WLANs), RFID tags, and 3G cellular systems rely on complex modulations that require specialized signal-analysis ...

The U.S. Department of Defense (DOD) has some “big challenges” when it comes to spectrum operations, with the environment becoming more and more congested. The National Strategic Research Institute ...

Have you ever wondered what the invisible world of radio waves might look like if you could actually see it? Rootkid explains how his project, the Spectrum Slit, transforms the unseen chaos of ...

When designing with interconnects, we're often concerned about issues such as crosstalk and reflections. We frequently ask for models from the manufacturers so we can run simulations to determine the ...

Current optical fibre transmission systems rely on modulation, coding and multiplexing techniques that were originally developed for linear communication channels. However, linear transmission ...

In Part 1 of this review, we discussed the basic architecture, specifications and controls of the Signal Hound BB60C real-time spectrum analyzer. In Part 2, we’ll show you some actual measurements and ...
