Sweep Subsystem
SWEep:POWer:STEP
SWEep:POWer:STEP <num>[lev suffix]lMAXimumlMINimum
SWEep:POWer:STEP? [MAXimumlMINimum]
Sets and queries the size of each power step. :STEP is governed by the
equation:
STEP = POWER SPAN/(POlNTS- 1).
l
POWER SPAN/STEP + 1
and a Parameter Bumped execution error will be reported.
l
POWER STEP = SPAN/(POlNTS- 1)
SPAN is normally an independent variable but will be changed to
l
STEP * (POINTS-l)
if both of these parameters are changed in the same message.
*RST value is 0.
