To investigate the stability of a switched-mode power supply, a Bode plot created with an oscilloscope is ideal for checking the critical phase margin and gain margin values. The factors that determine how satisfactory the results from Bode plot measurements will be, need to taken into consideration as part of the preparation.

Multi-tone testing has many benefits. While the multi-tone methodology was initially implemented to increase the speed of immunity testing, it has been found that this method also improves equipment efficiency, offers greater flexibility to truly test the equipment (EUT) under real world threat conditions, and can be fully compliant to standards.

This paper assesses how modern tools can be used to address poweraware SI challenges associated with I/O modeling, interconnect modeling, simulation, and analysis.
