NOTE: The 1MHz damped oscillatory waveform (3) has an effective pulse width of 4

μs. Equivalent peak pulse power at each of the pulse widths represented in

RTCA/DO-160E for waveforms 3, 4 and 5A (above) have been determined referencing Figure 1 herein as well as Application Notes 104 and 120 (found on

Microsemi’s website) and are listed below.
