Note: 25/30 cycles means the test is per- formed over 10 cycles if tested with 50 Hz AC power and 12 cycles if tested using 60 Hz AC power. Items indicated with an asterisk indicate this is something changed, new, or expanded for the 4th edition. The EFT/B test is specified to be performed using a 100 kHz repetition frequency.

lower limit of FCC B radiated testing. Now consider the same signaling rate but with a 10 ns risetime. This would, of course, represent a violation of the USB specification. Such a signal has a break frequency of 32 Mhz, and this signal would have significant spectral components above 30 Mhz. Field testing of low

The EFT waveform, as defined by the IEC 61000-4-4 standard, is intended to be used by manufacturers to test the performance of equipment when subjected to fast transients. Primarily, the testing involves injection of EFT pulses into the equipment’s AC power supply lines. The EFT waveform can also be injected into the signal and control lines,

0.1 m l Posted February 2002 It is the responsibility of the test laboratory to observe the results of the tests that are performed and to accurately report those results. As the responsible party (manufacturer, importer, etc) it is your responsibility to take those results, compare them against the specifications and standards, then, if appropriate make a declaration of conformity. As the responsible •Electrical Fast Transient (EFT) are produced when inductive loads such as relays or heavy duty motors are switched off. 13 EFT Generator EFT clamp EUT Link Partner •Industrial environment can have potential EFT sources close to Ethernet PHYs. •IEC61000-4-4 is the most common EFT Test Standard.
