I have a question on the ALC/Power search feature. We've been having some trouble with narrow, pulsed signals after installing a f/w update on our sig gen's. This datasheet sets the min p/w with ALC at 1 microsecond. My question is, do the power search and ALC features require some sort of settling time? Are there any preconditions we have to take into account before providing our UUT the pulse? Another question is, if we set the power accurately in CW and then switch to pulse, how critical is ALC or power search?
