Table 2. Settings for Twisted Pair Tests
Setting Description
Module Select DSX-5000 CableAnalyzer.
Cable Type Select a cable type that is correct for the type you will
test. To see a different group of cable types, tap MORE,
then tap a group. To make a custom cable type, see
Chapter 15.
NVP Nominal velocity of propagation. The tester uses the NVP
and the propagation delay to calculate the length of the
cable.
The default value is defined by the selected cable type
and is the typical NVP for that cable type. To enter a
different value, tap the NVP panel, then tap
or
on the NVP screen to increase or decrease the value.
To find the actual value for a cable, connect a known
length of the cable to the tester, tap MEASURE on the
NVP screen, then change the NVP until the measured
length matches the known length. Use a cable at least
30 m (100 ft) long.
When you increase the NVP value, the calculated length
increases.
Shield Test This setting shows only when you select a shielded cable
type. When you set Shield Test to On, the wire map test
includes a test for shield continuity.
Test Limit Select the correct test limit for the job. To see a different
group of limits, tap MORE, then tap the name of a
group.
Store Plot Data 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. The saved results show frequency-domain
measurements in a table and do not include the HDTDR/
HDTDX plots.
On
: The tester saves plot data for all frequency-
domain tests required by the selected test limit and for
the HDTDR/HDTDX analyzers.
