HISTory:POWer[:HISTogram]?
<supply>. Ten values are returned for the amount of time the <supply>'s power
spent in ten different power ranges. Those power ranges can be queried with the
and optional parameter. The units of the time values returned are HOURs by
MAX
default, but can be changed with the
returned for power ranges queried with the
values in milliwatts.

Default
none Selects the power supply whose power
histogram is desired. P5 is +5 Vdc
supply, N12 is -12 Vdc supply, etc.
none Returns the maximum or minimum of
the power range in milliwatts.
