This topic describes the parameters of the List / Step Sweep tab of the RF Output block.
The signal generator supports the following two types of sweeping through a set of frequency and amplitude points:
Step sweep provides a linear or logarithmic progression from one selected frequency, amplitude, or both, to another, pausing at linearly or logarithmically spaced points (steps) along the sweep.
Sweep steps are configured using the Frequency Start and Stop, Power Start and Stop, Dwell Time, and Step Points. Same Dwell Time is applied to all steps.
List sweep enables you to enter frequencies and amplitudes at unequal intervals, in nonlinear ascending, descending, or random order. Sweep steps are configured independently from the specified Frequency, Power, Dwell Time, and Waveform. Dwell time is editable at each point.

Sets the type of Sweep by toggling between the following two types of sweeps.
LIST - This type of sweep has arbitrary frequencies and amplitudes. Therefore, you need to specify frequency, power, dwell, and waveform for each step.
STEP - This type of sweep has equally spaced frequencies and amplitudes. Frequency and Power are calculated from step points and the same dwell time is applied to all steps.

Clicking this option performs the following two tasks:
Sets the Sweep Repeat setting to Single.
Initiates a single repetition of the configured sweep.
If the trigger is set to Free Run, the sweep is initiated as soon as you arm the sweep. When the sweep is armed, the signal generator begins the sweep as soon as the trigger is received.
This option is not active if Sweep Enable is set to Off.
