Today's spectrum analyzers aren't your father's instruments. Thanks to lots of embedded processing power, digital signal processing (DSP), and new analog front-end circuitry, the latest round of ...

For decades, if you wanted to make a millimeter wave spectrum analyzer measurement, you were forced to use large, heavy bench test equipment because there were no other options available. To make ...

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 ...

Although Tektronix calls the SA2600 spectrum analyzer a handheld instrument, “armheld” is more appropriate. Simply calling this battery operated instrument “portable” is misleading because engineers ...

Fourier transform infrared (FTIR) spectroscopy is the preferred method of infrared spectroscopy. In this approach, IR radiation passes through a sample, where some of it is absorbed by the sample ...
