2 Sweep Mode, Sweep Time
(1) Sweep Time
The sweep time mainly depends on span, RBW and VBW. It is in direct
proportion to span, and in inverse proportion to RBW and the minimum
value of RBW and VBW (the sweep time could be set randomly when the
span is 0). If the sweep time is too short, the system would remind 'UNCAL'.
Users need to increase the sweep time manually with the number keys,
knob or up/down key.
