Passive Intermodulation (PIM) occurs when multiple RF signals encounter defects in materials or workmanship in an RF path. These defects behave like a mixer causing noise to be generated at ...

A spectrum analyzer is a device that measures and displays Signal amplitude (strength) as it varies by frequency within its frequency range (spectrum). The frequency appears on the horizontal (X) axis ...

Modulation Measuring the quality of the modulation is important for making sure a system is working properly and that the information is being transmitted correctly. Understanding the spectral content ...

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 ...

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 ...

Digital circuitry can produce a wide range of harmonic frequencies and spectrum analyzers can show you this RF frequency spectrum (power or voltage), versus frequency. They are the one piece of gear ...
