Abstract
A test and measurement instrument, including at least one port configured to receive a signal from a device under test (DUT), the signal including a current signal acquired across a magnetic core of the DUT and a voltage signal acquired across the magnetic core of the DUT, and one or more processors. The one or more processors are configured to determine a hysteresis loop based on the current signal and the voltage signal, determine a magnetic flux of the magnetic core based on the voltage signal and the current signal for a number of sample points for each cycle, and determine a maximum magnetic flux for all cycles and a hysteresis loop cycle that corresponds to the maximum magnetic flux. A display configured to display at least one of the hysteresis loop, the signal received from the DUT, and the hysteresis loop cycle that corresponds to the maximum magnetic flux.
