Measuring Instantaneous Power Dissipation
in a Switching Transistor

The output transistor in a switching power supply is hotter than it
should be. You are concerned about its peak power dissipation. Set
up the TekScope instrument to measure the instantaneous power
dissipation of the transistor using an optional current probe.
