During the EFT tests, a UDP packet transfer was launched on each Gigabit Ethernet port. Each test level
and Gigabit Ethernet port was tested with two different PC software programs running on a laptop for
analysis, as described earlier. The test results are shown in

To verify the number of packets lost the program during the EFT tests, a UDP packet transfer was
launched on each Gigabit Ethernet port. Each EFT voltage test level and gigabit Ethernet port was tested
with two different software programs running on the laptop for analysis of throughput and packet errors
during an EFT event.
