Table 3-4. Items on the ELFEXT Results Screen
Item Description
Pairs
The pairs used in calculating the ELFEXT result. The pair not listed as the
Atten. Pair produced the FEXT used in the ELFEXT calculation
Atten.
Pair
The pair that produced the attenuation value used in the ELFEXT calculation.
Result
The overall result for the ELFEXT test. A PASS result means that the
calculated ELFEXT is higher than the value specified for the selected test
standard. A FAIL result means that the calculated ELFEXT is lower than the
specified value.
ELFEXT
(dB)
The worst margin and worst ELFEXT. The worst margin is the ELFEXT value
that is closest to falling below specifications, or the value that exceeds
specifications by the greatest amount. The worst ELFEXT is the lowest
ELFEXT value measured.
Frequency
The frequencies where the worst margin and worst ELFEXT values occurred.
Limit
The lowest ELFEXT values acceptable for the frequencies above.
Margin
The difference between the ELFEXT values and the limits. A positive number
means that the ELFEXT is higher than the limit. A negative number means that
the ELFEXT is lower than the limit.
