Syntax
POWer:SWLoss:NUMCYCles? <NR3>
Examples
POWER:SWLOSS:NUMCYCLES? might return the number of cycles for
switching loss calculation, if the POWer:TYPe is set to Switching Loss
(
POWer:TYPe:SWITCHingLoss). If the query times out with the Switching
Loss power enabled, it indicates the possibility of incorrect settings and might
return the following:
*ESR?
