The Sweep submenu defines the scope of measurement in the current channel. This includes the sweep type with various parameters, the trigger conditions and the periodicity of the measurement.
A sweep is a series of consecutive measurements taken over a specified sequence of stimulus values. It represents the basic measurement cycle of the analyzer.
The analyzer can perform sweeps at constant power but variable frequency (frequency sweeps), sweeps at constant frequency but variable power (power sweeps), and sweeps at constant power and frequency that are repeated in time (Time/CW Trigger Event sweeps); see Sweep Type.
The sweeps are further specified by the number of measurement points, the total measurement time and the trigger mode. A measurement may consist of a single sweep or a series of sweeps repeated continuously.
On the other hand, depending on the measurement task and the measured quantity, the measurement at each point can consist of several partial measurements with definite hardware settings.

The Sweep menu provides the following settings:
Sweep Type defines the sweep variable (frequency/power/time) and the position of sweep points in the sweep range.
Number of Points sets the total number of measurement points over the sweep range.
Frequency Step Size sets the distance between two consecutive frequency sweep points.
Sweep Time varies the measurement time for a sweep or delays the start of each sweep.
Trigger selects the trigger mode for the measurement.
Manual Trigger while the Manual trigger mode is active generates a trigger event. This softkey is also available in the Trigger submenu.
If Single (All Chans) is selected the measurement is terminated after a single sweep or a group of single sweeps defined in the Define Restart dialog.
Restart aborts the current measurement and restarts a new sweep sequence.
Define Restart opens a dialog to specify how many sweeps are repeated.
