Twisted Pair Autotest Results
47
The results are within the limit.
The selected test limit does not have a limit for the test, or
a dB rule applies. See the Technical Reference Handbook.
The results are within the range of accuracy uncertainty
for the tester. See “PASS*/FAIL* Results” on page 42.
The measurement shown for frequency-domain results is the
worst margin. (The insertion loss plot is different. See the
Technical Reference Handbook.)
 When more than one button shows at the bottom of the
screen, the tester highlights one in yellow to recommend
which one to tap. See “Buttons to Do Tests and Save Results”
on page 20.
Frequency-Domain Results
Frequency-domain results are the measurements that change
with frequency, such as insertion loss and crosstalk.
How to Save Frequency-Domain Results as a Plot or a Table
If Store Plot Data is on when you do a test, the saved results show
as plots. If Store Plot Data is Off, the tester does not save plot data
for frequency-domain tests or for the HDTDR/HDTDX analyzers.
You can see the plots before you save the test and exit the results
screen. Figures 19 and 20 show examples of the two types of
screens. Also see “Store Plot Data” on page 33.
