WebJul 5, 2015 · The bandwidth is the range of frequency beyond which a sinusoid is considered to be attenuated (conventionally, by -3dB or a factor of 1 / 2 ). However, digital signals are not sinusoids. WebOct 25, 2024 · In spectrum analysis, the resolution bandwidth (RBW) is defined as the frequency span of the final filter that is applied to the input signal. Smaller RBWs provide finer frequency resolution and the ability to differentiate signals that have frequencies that are closer together. Why not use the smallest RBW setting for all measurements?
