DIAGNOSTIC and FAULT INFO Tabs
If the Autotest failed or had a marginal result, the
FAULT INFO
tab shows. If the test passed and you selected
All Autotests
for
the
HDTDR/HDTDX
setting on the
TEST SETUP
screen, the
DIAGNOSTIC
tab shows. These tabs let you see the HDTDR and
HDTDX analyzer plots. The plots help you find the causes of NEXT
and return loss failures. See Chapter 6.
About dB Rules
For some test limits, the tester ignores the PASS/FAIL result from
some tests when a measurement is less than a specified value. For
example, the return loss measurement is not evaluated against
the limit at frequencies where insertion loss is less than 3 dB. This
is the 3 dB rule.
When a measurement is not evaluated against a limit, the tester
shows an for the result. On the plot for that measurement, the
limit line is black where the result is not evaluated against the
limit, as shown in Figure 69. When you upload the results to
LinkWare PC,
N/A
shows for the result.
The next sections summarize the dB rules. Tables 4 and 5 show the
dB rules that apply to each test and the test limits that use the
rules. For more information, see the Knowledge Base on the Fluke
Networks website.
