Headroom Test Error; Custom Cable Preferences And Cable Parameters; Creating A New Custom Cable Type - IDEAL Networks LanTEK III Manual

The headroom test is a simple way to indicate the margins available on a cable line for
faultless support of an application. This test also indicates the additional margin obtainable
by using "improved" cables and connections, as well as careful installation.

Headroom Test Error

The headroom value indicated in dB identifies the minimum margin available for a cable
line. A high value is preferable, since it indicates a strong signal and minor perturbations.
The pass/fail limits for the margin are identical with those for Power Sum ACR-N (ACR).

Custom Cable Preferences and Cable Parameters

All cable types pre-programmed in LanTEK
standard. These pre-programmed preferences cannot be changed. If you wish to perform
other tests on a selected cable line, you first must create a custom cable.
Example: In addition to TIA 568B Category 5 tests, the return loss is to be measured (which
is not required by TIA). For this purpose, a custom cable is created and the tests selected
that are to be included in the test series for this cable.
A maximum of ten (10) custom cables can be created, stored, deleted and, if required,
loaded.
