The HDTDX Analyzer
While NEXT test results shows crosstalk signals relative to frequency,
the HDTDX
™
(High-Definition Time Domain Crosstalk) analyzer shows
crosstalk signals relative to their distance from the tester. The HDTDX
plot shows the locations and amplitudes of crosstalk signals to help
you find the causes of NEXT and ACR-F failures.
After an Autotest, you can see HDTDX plot if the Autotest had a FAIL,
FAIL* or PASS* result, or if HDTDX/HDTDR on the TEST SETUP screen
was set to All Autotests when you did the test.
To see the HDTDX plot for an Autotest, tap the DIAGNOSTIC tab on
the Autotest results screen, then tap HDTDX ANALYZER. Figure 68
shows an example of an HDTDX plot.
Note
If Store Plot Data is off, the tester does not
include the HDTDX plot with results you save.
To get HDTDX analyzer results you can also tap Tools > Diagnostics,
but you cannot save these results.
Figure 68 shows how some common faults appear on HDTDX plots.
