Selecting sweep
You can set the length of time that the instrument takes to tune across the displayed
frequency span or, in zero span, the time that the instrument takes to sweep the full
screen. Reducing the sweep time increases the sweep rate. The default setting so the
sweep mode are Continue and Normal to sweep continuously at a normal speed for
most on-going measurements. If you want to hold the measurement or get a single
sweep, you can change the sweep mode.
