Keysight E8402A, E8404A C-Size Mainframes User and Service Guide 101HISTory Subsystem Programming the Enhanced MonitorHISTory:VOLTage[:HISTogram]? <supply>[,MIN|MAX]HISTory:VOLTage[:HISTogram]? returns the voltage histogram data heldfor the . Ten values are returned for the amount of time the ’svoltage spent in ten different current ranges. Those voltage ranges can bequeried with the MIN and MAX optional parameter. The units of the time valuesreturned are HOURs by default, but can be changed with the HISTory:UNIT[:TIME]command. The units returned with the MIN or MAX parameters are millivolts.ParametersReturned DataComments– HIST: VOLTage? P5 returns 10 time values, units set/queried by HIST:UNIT.– HIST: VOLTage? P5,MAX returns 10 voltages (in millivolts) representing themaximums for each voltage range for the 5 volt supply.Name Type Range Default Description<supply> enum.
