The 10/700us waveform called out by IEC 61000-4-5 is essentially the same as the 9/720us waveform called for by FCC. Both require circuits based on old CCITT documents. There are some generators on the market that will meet both requirements (tolerances for each allow for the overlap). Older generators designed to meet only the CCITT or IEC specification may not also meet the 9/720us requirements of FCC. Both specify a 20uF energy storage capacitor for this waveform... Hope this helps... Mike Hopkins Thermo KeyTek
