Some traditional common mode techniques
do not work in differential mode situations
Once a common mode problem is determined, use techniques which have a
good potential for success. Start by analyzing the ground and power distribution
system. Understand what RF impedances these systems present, and then
reduce the excessive impedance. These techniques can be tried:
