description in the Agilent CSA Spectrum Analyzers
User’s/Programmer’s Reference Guide.)
NOTE To resolve two signals of equal amplitude, the resolution bandwidth
must be less than the signal separation. For example, if the signal
separation is 200 kHz and the analyzer only has resolution bandwidth
settings in a 1-3-10 sequence, a 100 kHz RBW is the best choice for the
200 kHz signal separation. But some analyzers, such as the Agilent
CSA and PSA spectrum analyzers, can select a 180 kHz RBW.
