These parameters control the digital filtering and post¬processing that determine the effective noise floor, amount of trace noise and, in some special cases, immunity to interfering signals. The trade off for improved noise performance is slower sweep speed. Figure 3-1 provides an example of two IF-bandwidth settings. Settings
