The signal generator provides leveled output power sweeps at CW frequencies and in conjunction with frequency sweeps. Power level sweeps can be from a set to sweep from high level to a low level range or from a low to a high level range. Power level sweeps can be selected to be linear or logarithmic. Level sweep menus provide the sweep range, the step size, the dwell time-per-step, and the type of power sweep (linear or logarithmic), sweep direction, and sweep trigger.
