NEXT@REMOTE Results
The NEXT@REMOTE test and its results are identical to the NEXT test
described above, except that the NEXT@REMOTE measurements are taken from
the remote end of the cable and sent to the main unit.
ACR
The ACR test calculates the ratio of attenuation to crosstalk (ACR) for each
combination of cable pairs. ACR is expressed as the difference (in dB) between
the measured NEXT and attenuation values. ACR is calculated using values
obtained from the NEXT and attenuation tests.
ACR Results
The first ACR results screen shows the NEXT pairs and attenuation pair used to
calculate the ACR result, the worst-case ACR margin, and a PASS or FAIL
result for each set of pairs.
To see detailed results for the cable pairs, use D U to highlight the pairs; then
press @ View Result. Table 3-6 describes the items on the ACR results
screen.
