Frequency Linear Sweep

Sweeps linearly from start to stop frequency in constant steps. Frequency step size is
(f_stop-f_start)/number_of_points. If start<stop then negative frequency steps are
performed.

Frequency Log Sweep

Sweeps logarithmically from start to stop frequency in a given number of points per
decade.

Frequency Random Sweep

The output frequency is selected randomly between start and stop frequency. The

number of different output frequencies is determined by the number of points selected by
the user.

Power Sweep (Figure 8)

To run a power sweep, enter start and stop power in dBm unit, the number of steps,
dwell and off time in milliseconds. Dwell time is at least 50 µs, the sum of the dwell and
off time must be at least 400 µs. When “auto” is selected, the off time is automatically
adjusted such that during switching transients the output is disabled and the sum of
dwell and off time are at least 400 µs.
Select, if the sweep should be run a predefined number of times (enter desired number)

or infinite times (selecting infinite). Select ALC settings. Start and stop the sweep by
pressing the ON/OFF button.
