Review of MIL-STD-461 CS116 Damped Sinusoidal Transients, Cables and Power Leads

Introduction

In this article, I am delving into the evolvement of CS116 testing, the background, the purpose and how the testing is approached today. The test title is, “Conducted susceptibility, damped sinusoidal transients, cables and power leads”. MIL-STD-461 assigns applicability to a broad variety of applications and states the purpose to is to verify the ability of the EUT to withstand damped sinusoidal transients (Figure 1) coupled onto EUT associated cables and power leads.

Evolvement

Looking back, we find that testing for this risk was introduced August 4, 1986, via the MIL-STD-462 Notice 5 release, adding test methods CS10 (pin injection) and CS11 (capacitive or inductive indirect). A short time later (15 October 1987) MIL-STD-462 Notice 6, supplemented by adding CS12 (a current pulse injection method) and CS13 (a single wire coupled pulse). Recall that…
