LeCroy’s WaveMaster 8 Zi digital oscilloscopes, Agilent’s N9030A PXA spectrum analyzer, and Tektronix's RSA6120A spectrum analyzer are top of the list for test and measurement in 2009. Test-equipment ...
The RSA3408A can display frequency-domain plots over time, a feature that lets you see how the frequency content of a signal changes. That's important for viewing signals on devices such as cell ...
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 ...
[VK2ZAY] has a thing for 555 chips. Before the ready availability of microcontrollers, the 555 was the hardware hacker’s swiss army knife. After all, even though the chip is supposed to be a timer, it ...
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 ...
