Keysight E8402A, E8404A C-Size Mainframes User and Service Guide 77HISTory Subsystem Programming the Enhanced MonitorHISTory:POWer[:HISTogram]? <supply>[,MIN|MAX]HISTory:POWer[:HISTogram]? returns the histogram data held for the. Ten values are returned for the amount of time the ’s powerspent in ten different power ranges. Those power ranges can be queried with theMIN and MAX optional parameter. The units of the time values returned areHOURs by default, but can be changed with the HISTory:UNIT[:TIME]command.The units returned for power ranges queried with the MIN or MAXparameters are integer values in milliwatts.ParametersReturned DataComments– HIST:POW? P5 returns 10 time values for +5V supply.– HIST:POW? P5,MAX returns 10 values representing the maximum powerfor each power range in milliwatts.Name Type Range Default Description<supply> enum.
