Setting Description
Module Select DSX-8000 CableAnalyzer or 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 19.
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.
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 insertion
loss or for the HDTDR analyzer. You can see the plots
before you save the test and exit the results screen. The
saved results show insertion loss measurements in a table
and do not include the HDTDR plot.
On : The tester saves plot data for the insertion loss
test and for the HDTDR analyzer.
