[SNIP] The results MAY be different. If you have an analog swept measurement system, then the observation (resolution) bandwidth is swept continuously across the span range. You will see everything (as long as the sweep rate is slow enough to allow the detector to properly respond). If you have a stepped (hopped) measurement system, it is possible to specify a resolution bandwidth and a step size which allows for unviewed "gaps" between the sampled frequencies. The right way to use a stepped tuning system is to specify a step size that's no more than half the resolution bandwidth. And you have to dwell at each step frequency long enough for your detector to properly respond.
