Here you can select, create and change the cable type to be tested and the desired test
parameters.
Figure 28 - Cable types and test parameters - Cu
The menu screen is divided into three main sections:
On the left
is the default cable type list with templates for the creation of test standards.
These serve as the basis for your own test configurations and extend to include self- created
test specifications. External test standards can also be imported.
At the top right,
you can find the details of the test standard currently used that is assigned
to the project currently open. These include the name of the test standard and the cable
constant for length determination, the propagation factor {NVP value} of the installed
cable. In order to be able to determine the cable length correctly, the device requires the
cable-specific values for NVP. Either you take this value from the data sheet of the cable or
the NetXpert XG2 determines the values on a cable of known length {>3Om}.
In the lower right section,
you will find the details for the test standard. Under
Speed
,
set the maximum Ethernet speed used for testing. Please note that, depending on the model
of the device, fewer options may be available here. If the range is not sufficient for the
requirements to be tested, your NetXpert XG2 can be upgraded at any time via a firmware
license.
The cable structure is specified in the next two columns.
Cable Shield
takes into account
whether the installed cable is with or without shielding. Error messages are issued
as soon as the tested cable deviates from the setting as long as
Ignore Shield
is not selected
here.
Under
Cable wiring
, you can select the orientation (crossover or straight through) and
number of wire pairs. Error messages are issued as soon as the tested cable deviates from
the setting as long as
Ignore X-over
is not selected here.
