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 ...

Optimizing the performance of spectrum and signal analyzers involves trade-offs based on each instrument’s strengths and weaknesses. Keysight Technologies’ Sai Yang, product manager microwave and ...

Wireless devices that periodically hang, interfere with other consumer products (like radios), or don't completely deliver as promised can turn consumers off, not only to the technology but to the ...

Technological innovation in RF continues to advance relentlessly, due in large part to sustained growth in the military and communications sectors. Commercial communications networks and modern radar ...

A spectrum analyzer measures the magnitude of an input signal versus frequency within the specified frequency range of the instrument. The major use is to measure the unknown signals on different ...

No doubt one of the most revolutionary tools for the RF side of broadcasting was the advent of the network analyzer. Prior to its invention, measuring the response of an antenna system was more or ...

Modern embedded system designs present challenges for EMI testing and troubleshooting that didn’t exist years ago. These challenges include switching power supplies, high speed system clocks and data ...

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 ...
