"Webfollowing range of RBW settings: RBW: 1 MHz, 2 MHz, 5 MHz, 10 MHz, 20 MHz and 50 MHz The measurement of peak and average power requires the spectrum analyzer to use a wide video bandwidth filtering that avoids any impact on the output signal of the RBW filtering and detection. The FSW spectrum analyzer was therefore set to use a VBW " - Rbw and vbw
