1. A method for power management in a test instrument, comprising:
identifying controllable components in the test instrument that are to be turned on or off by a power management application, wherein the test instrument is a portable equipment that operates on batteries and monitors and tests an optical network;
identifying a combination of components, selected from the controllable components, that are to be turned off together at a same time in a given operational state of the test instrument;
determining power consumption of the controllable components and power consumption of the combination of components under the given operational state of the test instrument;
generating a system-wide power management model based, at least in part, on the power consumption of the controllable components and the power consumption of the combination of components, wherein the system-wide power management model comprises scenes, and wherein each of the scenes defines at least a list of the controllable components and respective on or off power states for each component in the list of the controllable components;
generating a scene table for the given operational state of the test instrument, the scene table comprising selected scenes from the scenes of the system-wide power management model, wherein one of the selected scenes in the scene table includes the combination of components that are to be turned off at the same time; and
executing the selected scenes in the scene table, including turning the combination of components off together at the same time, to determine a power consumption level of the test instrument in the given operational state, wherein the system-wide power management model is adjusted based on the determined power consumption level of the test instrument.
