ResBW Metric
Menu Path:
lets you choose the way that the width of the RBW Resolution Band Width (RBW or ResBW): specifies the minimum frequency bandwith that two separate frequency spectra can be resolved and viewed seperately. For FFT (digital) based VSA's the process is equivalent to passing a time-domain signal through a bank of bandpass filters, whose center frequencies correspond to the frequencies of the FFT bins. For a traditional swept-tuned (non-digital) spectrum analyzer, the resolution bandwidth is the bandwidth of the IF filter which determines the selectivity. filter is specified for the measurement.
This parameter is only available with Power Spectrum, Adjacent Channel Power and Spectral Emissions Mask measurements.
