Sets a logarithmically determined sweep step size for the RF level sweep. It is expressed in decibels and you must enter the value and the unit dB with the command.
The level is increased by a logarithmically calculated fraction of the current level according to:
step_sizen+1 = Leveln + step_sizen x Leveln
Leveln+1 = Leveln + step_sizen+1
with LevelSTARt < levelSTOP, step_size = SWE:POW:STEP[:LOG] and n = number of sweep steps
This parameter correlates with the number of steps SWE:POW:POIN within the sweep range as follows:
level_points = ((LevelSTOP - LevelSTARt) / step_size) + 1)
If you change the step size, the number of steps changes accordingly. The sweep range remains the same.
