While it’s seldom necessary (post-installation, anyway) to test the physical-layer behavior of a wired LAN infrastructure, the same cannot be said for wireless LANs. Many elements, including fading, ...

With the increasing implementation of wireless (Wi-Fi, Bluetooth, ZigBee) and many other wireless protocols, it’s increasingly important for product designers to feel competent in using spectrum ...

We all love our wireless devices. We want more features, higher data rates, and improved range. These demands, in turn, require advanced digital protocols. Meanwhile, the number of signal sources is ...

You ever wonder where the previous week went? The previous quarter? The previous year? I do all the time. I like to write off this phenomenon as a side effect of being always busy, that itself a key ...

The crowded RF spectrum, compounded by the explosion in application spaces joining the cloud, demands advanced development tools able to provide deeper insights into signals and their measurement. Our ...

Using a spectrum analyzer to measure noise signals requires several additional factors, such as sensitivity or how well the instrument can measure small signals. The analyzer’s noise floor specifies ...

Munich, Germany. Rohde & Schwarz has launched the R&S ZNL vector network analyzer and the R&S FPL1000 spectrum analyzer to offer flexible solutions for important RF measurements. Capabilities include ...

Tracking down interference with conventional spectrum analyzers can be difficult if the interference is intermittent. This week Tektronix announced the H500 and SA2500 handheld spectrum analyzers with ...

Hopefully by now most of us know better than to rent a modem from an internet service provider. Buying your own and using it is almost always an easy way to save some money, but even then these pieces ...

Back in the 1960s, when I started working in radio broadcast engineering, an oscilloscope was my “eye” on what was happening with equipment. That tool served me well and is still in daily use in my ...
