Peter,
Yes, for crystals and narrowband filters, we needed a separate mode with much longer settling time. We chose a specific span, 100 kHz, as the switchover point, assuming that people who want to look at the pass band of a device with less than 10 kHz bandwidth would do it with a narrow span. For wideband rejection, where maybe a parasitic capacitance dominates, the faster sweep mode should work fine.
