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 ...

Modern wireless communications are using increasingly wide bandwidth-modulation schemes, and packet communications are getting faster. Transmissions are increasingly time-varying. Radios often ...

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 RTL-SDR dongles get most of the love from people interested in software-defined radio, but the Pluto is also a great option, too. [FromConceptToCircuit] shares code to turn one of these radios ...

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 ...

Just as the oscilloscope is the instrument of choice for analog electronics, and the spectrum analyzer is preferred for RF measurement, the logic analyzer is the go-to instrument for digital system ...

Long time readers know I like to test compact and, where possible, low-cost equipment. Recently I found another tool to add to my backpack when I get back on the road. Seven years ago, wanting a ...

Let’s say a corporate engineer or a consultant is coming to your station to diagnose and repair a problem using an RF spectrum analyzer. This would be a great time to schedule a meeting with your ...
