Set the sweep mode to “Single”. The number on the parameter icon denotes the current sweep
number.
2. Numbers
Set the number of sweeps for a single sweep. In single sweep mode, the system executes the
specified number of sweeps and the number shown on the icon in the status bar at the left of the
screen varies with the process of the sweep.
3. Continue
Set the sweep mode to “Continue”. The character Cont on the parameter icon denotes the
analyzer is sweeping continuously.
 If the instrument is in single sweep mode and no measurement function is enabled, press this
key and the system will enter continuous sweep mode and sweep continuously if the trigger
conditions are satisfied.
 If the instrument is in single sweep mode and a measurement function is on, press this key
and the system will enter continuous sweep mode and measure continuously if the trigger
conditions are satisfied.
 In continuous sweep mode, the system will send a trigger initialization signal automatically
and enter the trigger condition judgment directly after each sweep.
