While [Vinod] says he’s not an expert in this sort of thing, we really like his audio spectrum analyzer build from a simple microcontroller and LCD display. It is a well-studied fact that every audio ...

Multichannel I/Q analysis provides a powerful, integrated way to see and measure complex RF behaviors across multiple inputs.

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 ...

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 ...

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 ...

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 ...

For a long time, spectrum analyzers and scanning receivers have been widely used in EMI laboratories. The technical capabilities of these instruments are similar to those of a classic stepped EMI ...

Your wireless users are raving about their increased mobility and freedom with your now-operational WLAN, but celebration is the last thing on your mind: Your IT team has been stuck manually tracing ...

Software for Anritsu’s Field Master spectrum analyzer performs uplink interference measurements in 5G and LTE time division duplexing (TDD) networks. This measurement is now included in the analyzer’s ...

A hardware device or software used to examine the frequency and power components of a signal. It provides more information than an oscilloscope, because it can display the signals over a range of ...
