What is alternating current (AC)?
281Alternating current (AC) is a type of electric current whose polarity reverses periodically and whose amplitude varies continuously over time. AC power is often used in businesses and homes because it is cheaper and more efficient to generate and transmit than direct current (DC) power. During transmission, a transformer can reduce power loss by increasing or decreasing the voltage of the AC line. Alternating current (AC) is a form of household electricity -...

What are spectrum analyzers used for?
503Spectrum analyzers measure the amplitude of an input signal versus frequency over the entire frequency range to determine the power of the signal. Spectrum analyzers are capable of performing tests such as noise figure and signal-to-noise ratio (SNR) to characterize the performance of a device and its contribution to overall system performance. For more information, see the application guide Spectrum Analysis Basics. ,
