One of the most useful pieces of test gear to become generally available to the average broadcast engineer in the last 20 years or so is the spectrum analyzer. This electronic tool, while still rather ...

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 ...

I suppose most of us have had the experience of going to the mailbox and seeing that telltale package in the white plastic bag, the sign that something has just arrived from China. This happened to me ...

Frequency domain analysis provides a powerful tool for assessing the performance of devices and networks. By viewing the amplitude of the signal across a range of narrow frequency channels, designers ...

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 ...

This application note discusses on using a passive probe which is commonly used in an oscilloscope, only in this case, it will be used for a spectrum analyzer. A portion of the preferences and ...

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 ...

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 ...
